Tamper-resisting multipart negotiable instruments

Claim 1

A multipart negotiable instrument having improved resistance to tampering after inscription of an image thereon, said instrument comprising at least a first generally planner web and a second generally planar web, said first web defining a first surface and a second surface, said second surface including means for transferring an image to a surface in contact with the image-transferring means when a corresponding image in inscribed upon the first surface of said first web; said second web being secured to said first web in stacked relation therewith, and defining a first surface and a second surface, said first surface being in contact with the second surface of said first web, the first surface of said second web being imprinted in selected zones and not in other zones with an image receiving layer which is erasably bonded in said selected zones to said first surface, said image receiving layer being a particulate matrix comprising particulate materials and a binder, said image receiving layer also being in register with at least a portion of said image transferring means of said first web and capable of receiving on the surface of said image receiving layer an image from said image transferring means when a corresponding image is inscribed against the first surface of said first web; said image receiving layer being so erasably bonded to the second web that when an image is transferred onto the surface of said image receiving layer from said image transferring means said image remains on said surface of said image receiving layer and when an effort is made to erase it or remove it with an organic solvent, the image receiving layer and image are removed in the zone of erasure and the image receiving layer and image are defaced in the zone of attempted removal with organic solvent.

Claim 17

A method of preparing a multipart negotiable instrument having improved resistance to tampering comprising the steps of: (a) providing a first, generally planar web defining a first surface and a second surface; (b) applying a layer of a material for transferring an image on at least a portion of the second surface on the first web to form an image transferring means; (c) providing a second, generally planar web defining a first surface and a second surface; (d) imprinting a layer of an image receiving material to the first surface of the second web in selected zones thereof to form an image receiving layer capable of receiving an image transferred from said image transferring means when said means is in contact with said layer and a corresponding image is inscribed against the first surface of said first web, said image receiving layer comprising a particulate matrix erasably bonded to the first surface of the second web and defacable when rubbed with organic solvents, said layer being removable when a adhesive coated adhesive tape is applied to said image receiving layer and then pulled away therefrom; (e) overprinting said first surface with a pattern at least in said selected zones; and (f) securing said first web and said second web together in stacked relation so that at least a portion of the image transferring means on said second surface of said first web is in contact and register with at least a portion of said image receiving layer on the first surface of said second web, whereby when an image is transferred onto the surface of said image receiving layer from said image transferring means said image remains on said surface of said image receiving layer and when an effort is made to erase or remove the image, at least a portion of the image receiving layer and of said pattern is moved with the image.

Claim 18

A method of preparing a multipart negotiable instrument having improved resistance to tampering comprising the steps of: (a) providing a first, generally planar web defining a first surface and a second surface; (b) applying a layer of a material for transferring an image on at least a portion of the second surface on the first web to form an image transferring means; (c) providing a second, generally planar web defining a first surface and a second surface; (d) imprinting a layer of an image receiving material to the first surface of the second web in selected zones thereof to form an image receiving layer capable of receiving an image transferred from said image transferring means when said means is in contact with said layer and a corresponding image is inscribed against the first surface of said first web, said image receiving layer comprising a particulate matrix erasably bonded to the first surface of the second web and defacable when rubbed with organic solvents, said layer being removable when a adhesive coated adhesive tape is applied to said image receiving layer and then pulled away therefrom; (e) overprinting said first surface with a pattern at least in said selected zones; and (f) securing said first web and said second web together in stacked relation so that at least a portion of the image transferring means on said second surface of said first web is in contact and register with at least a portion of said image receiving layer on the first surface of said second web, whereby when an image is transferred onto the surface of said image receiving layer from said image transferring means said image remains on said surface of said image receiving layer and when an effort is made to erase or remove the image, at least a portion of the image receiving layer and of said pattern is moved with the image.

Claim 23

A method of using a book of ticket blanks to provide improved resistance to tampering after a ticket in said book of ticket blanks is issued comprising the steps of: (a) providing the book of ticket blanks containing at least one, first paper web for transferring images to a ticket blank having improved resistance tampering, and at least one, second paper web defining a ticket blank having improved resistance to tampering, said first and second paper webs being secured within the book in stacked, registered relation; said first paper web defining a first surface and a second surface, said second surface of said first paper web including an image transferring means; the second paper web being generally planar, removably secured within said book and defining a first surface and a second surface; the first surface of said second paper web being at least in part imprinted in selected zones only with an image receiving layer capable of receiving an image transferred from said first paper web when a corresponding image is inscribed upon the first surface of said first paper web, said image receiving layer being erasably bonded in said selected zones to said first surface, said image receiving layer being a particulate matrix comprising particulate materials and an organic binder; said image transferring means comprising a colorant dispersed in a hydrophobic medium, the colorant-medium dispersion of the image transferring means having a penetrometer value of about 5 to about 30 when in the form of a block prior to formation of said means, said image transferring means of said first paper web and said image receiving layer of said second paper web being at least partially in contact and in register when an image is to be transferred therebetween; said image receiving layer being so erasably bonded to the first surface of the second paper web that when an image is transferred onto the surface of said image receiving layer from said image transferring means said image remains on the surface of said image receiving layer and when an effort is made to erase or remove it by rubbing with an organic solvent, the image receiving layer and image are removed in the zone of the erasure and the image receiving area is defaced in the zone of attempted removal with organic solvent; (b) inscribing an image on the book of ticket blanks and transferring a corresponding image from at least the transferring means of the second surface of said first paper web to an image receiving layer on the first surface of said second paper web; and (c) issuing the book of ticket blanks containing the corresponding image so transferred.

Claim 24

A method of using a book of ticket blanks to provide improved resistance to tampering after a ticket in said book of ticket blanks is issued comprising the steps of: (a) providing the book of ticket blanks containing at least one, first paper web for transferring images to a ticket blank having improved resistance tampering, and at least one, second paper web defining a ticket blank having improved resistance to tampering, said first and second paper webs being secured within the book in stacked, registered relation; said first paper web defining a first surface and a second surface, said second surface of said first paper web including an image transferring means; the second paper web being generally planar, removably secured within said book and defining a first surface and a second surface; the first surface of said second paper web being at least in part imprinted in selected zones only with an image receiving layer capable of receiving an image transferred from said first paper web when a corresponding image is inscribed upon the first surface of said first paper web, said image receiving layer being erasably bonded in said selected zones to said first surface, said image receiving layer being a particulate matrix comprising particulate materials and an organic binder; said image transferring means comprising a colorant dispersed in a hydrophobic medium, the colorant-medium dispersion of the image transferring means having a penetrometer value of about 5 to about 30 when in the form of a block prior to formation of said means, said image transferring means of said first paper web and said image receiving layer of said second paper web being at least partially in contact and in register when an image is to be transferred therebetween; said image receiving layer being so erasably bonded to the first surface of the second paper web that when an image is transferred onto the surface of said image receiving layer from said image transferring means said image remains on the surface of said image receiving layer and when an effort is made to erase or remove it by rubbing with an organic solvent, the image receiving layer and image are removed in the zone of the erasure and the image receiving area is defaced in the zone of attempted removal with organic solvent; (b) inscribing an image on the book of ticket blanks and transferring a corresponding image from at least the transferring means of the second surface of said first paper web to an image receiving layer on the first surface of said second paper web; and (c) issuing the book of ticket blanks containing the corresponding image so transferred.
