Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
62 words
A protective laminar assembly for lamination to an information-bearing document, said assembly comprising a plastic sheet material having an adherent capability and a verification pattern of a light-transmissive pigment material having an average particle size between about 1 to about 25 microns and a dry brightness value of no greater than about 95 integrated with said sheet material or said adherent capability.
Claim 2
Dependent Claim
62 words
A protective laminar assembly for lamination to an information-bearing document, said assembly comprising a plastic sheet material having an adherent capability and a verification pattern of a light-transmissive pigment material having an average particle size between about 1 to about 25 microns and a dry brightness value of no greater than about 95 integrated with said sheet material or said adherent capability.
Claim 3
Dependent Claim
15 words
A laminar assembly of claim 1 where said pattern is coated on said adherent capability.
Claim 4
Dependent Claim
12 words
A laminar assembly of claim 1 where said pigment material comprises silica.
Claim 5
Dependent Claim
17 words
A laminar assembly of claim 1 where said pigment material is dispersed in said plastic sheet material.
Claim 6
Dependent Claim
48 words
A laminar assembly of claim 1 where said plastic sheet material having said adherent capability comprises the front sheet member of an envelope comprising front and back sheet members having approximately the same dimensions and where said front sheet member is adapted to lamination to said information-bearing document.
Claim 7
Dependent Claim
21 words
A laminar assembly of claim 1 where said adherent capability comprises a layer of adhesive carried by said plastic sheet material.
Claim 8
Dependent Claim
21 words
A laminar assembly of claim 6 where said pattern is positioned between said plastic sheet material and said layer of adhesive.
Claim 9
Dependent Claim
15 words
A laminar assembly of claim 6 where said pattern is coated on said adhesive layer.
Claim 10
Dependent Claim
19 words
A laminar assembly of claim 8 where said pigment is dispersed in a binder material which is water swellable.
Claim 11
Dependent Claim
19 words
A laminar assembly of claim 8 where said pigment is dispersed in a binder material which is water soluble.
Claim 12
Dependent Claim
74 words
A protective laminar assembly for lamination to an information-bearing document, said assembly comprising a plastic sheet material carrying a layer of adhesive and a pattern comprising a light-transmissive pigment material coated on said adhesive layer, said pigment being dispersed in a binder material which is at least water swellable, said light-transmissive pigment material having a particle size between about 1 to about 25 microns and a dry brightness value no greater than about 95.
Claim 13
Dependent Claim
74 words
A protective laminar assembly for lamination to an information-bearing document, said assembly comprising a plastic sheet material carrying a layer of adhesive and a pattern comprising a light-transmissive pigment material coated on said adhesive layer, said pigment being dispersed in a binder material which is at least water swellable, said light-transmissive pigment material having a particle size between about 1 to about 25 microns and a dry brightness value no greater than about 95.
Claim 14
Dependent Claim
59 words
A laminar assembly of claim 11 where said plastic sheet material carying said layer of adhesive and said light-transmissive pigment material coated on said adhesive layer comprises the front sheet member of an envelope comprising front and back sheet members having approximately the same dimensions and where said front sheet member is adapted to lamination to an information-bearing document.
Claim 15
Dependent Claim
95 words
A protective laminar assembly for lamination to an information-bearing document, said assembly comprising in order, a sheet of a cellulose tiracetate having a hydrolyzed surface, and adhesive layer comprising a mixture of a low molecular weight polyvinyl acetate and a hydrolyzed polyvinyl alcohol coated on the hydrolyzed surface and a pattern of light-transmissive pigment material having a particle size between about 1 to about 25 microns and a dry brightness value no greater than about 95, said pigment being dispersed in a binder material which is at least water swellable coated on said adhesive layer.
Claim 16
Dependent Claim
95 words
A protective laminar assembly for lamination to an information-bearing document, said assembly comprising in order, a sheet of a cellulose tiracetate having a hydrolyzed surface, and adhesive layer comprising a mixture of a low molecular weight polyvinyl acetate and a hydrolyzed polyvinyl alcohol coated on the hydrolyzed surface and a pattern of light-transmissive pigment material having a particle size between about 1 to about 25 microns and a dry brightness value no greater than about 95, said pigment being dispersed in a binder material which is at least water swellable coated on said adhesive layer.
Claim 17
Dependent Claim
78 words
A protective laminar assembly for lamination to an information-bearing document, each assembly comprising in order, a polyester sheet material, and adhesive layer comprising an ethylene-ethyl acrylate copolymer, and a pattern of light-transmissive pigment material having a particle size between about 1 to about 25 microns and a dry brightness value of no greater than about 95, said pigment being dispersed in a binder material which is at least water swellable or water soluble coated on said adhesive layer.
Claim 18
Dependent Claim
78 words
A protective laminar assembly for lamination to an information-bearing document, each assembly comprising in order, a polyester sheet material, and adhesive layer comprising an ethylene-ethyl acrylate copolymer, and a pattern of light-transmissive pigment material having a particle size between about 1 to about 25 microns and a dry brightness value of no greater than about 95, said pigment being dispersed in a binder material which is at least water swellable or water soluble coated on said adhesive layer.
Claim 19
Dependent Claim
107 words
A protective laminar assembly for lamination to an information bearing document, said assembly comprising in order, a polyester sheet material, an adhesive system comprising a layer which comprises an ethylene-ethyl acrylate copolymer coated on the polyester sheet material and a layer of mixture of a polyvinyl alcohol and a polyvinyl pyridine coated on the copolymer containing layer, and a pattern of light-transmissive pigment material having a particle size between about 1 to about 25 microns and a dry brightness value of no greater than about 95, said pigment being dispersed in a binder material which is at least water swellable coated on said layer of said mixture.
