I. d. card laminar structures and processes for making same

Claim 2

A laminar structure as defined in claim 1 wherein said photo ID card comprises a dyeable stratum containing a color diffusion transfer image.

Claim 3

An ID product comprising a laminar structure as defined in claim 1, said structure being confined in the space defined by a transparent sheet material sealed along its periphery to another sheet material.

Claim 4

An ID product comprising a single sheet of flexible opaque material folded at substantially the center to provide two substantially equal parts, a transparent sheet material sealed along at least three edges to a surface of one of said parts to define a pouch for confining a substantially planar object, and a laminar structure as defined in claim 1 confined within said pouch.

Claim 5

A laminar structure comprising an image-receiving element including a dyeable stratum containing a color diffusion transfer image and a protective overlay laminated to said stratum, said overlay comprising, in order, a first transparent layer of polyvinyl alcohol; a layer of a transparent, molecularly oriented, non-cross-linked, polyvinyl alcohol, a portion of which has been dyed with a dichroic dye; a second transparent layer of polyvinyl alcohol; and a transparent sheet material comprising cellulose triacetate, the laminated surface of which has been hydrolyzed, said stratum containing said color image being bonded to said first polyvinyl alcohol layer, said layer of molecularly oriented polyvinyl alcohol being water-permeable whereby water permeating through said vinyl polymer layer toward said sheet material will cause said vinyl polymer layer to separate from said sheet material.

Claim 6

A laminar structure as defined in claim 6 wherein said dyeable stratum comprises a mixture of polyvinyl alcohol and polyvinyl pyridine.

Claim 7

A laminar structure as defined in claim 6 wherein said dichroic dye is applied in the form of at least one stripe.

Claim 8

The process which comprises exposing a photosensitive element comprising at least one light-sensitive silver halide layer and associated dye developer to form a developable image; developing said image by applying an aqueous alkaline processing fluid and as a function of development forming an imagewise distribution of diffusible dye developer; transferring said imagewise distribution, at least in part, by imbibition, to a superposed dyeable stratum comprising a mixture of polyvinyl alcohol and polyvinyl pyridine to impart thereto a positive color transfer image; and laminating said image in the presence of moisture to a protective overlay comprising a transparent sheet material carrying on one side thereof, in order, a first transparent layer of polyvinyl alcohol; a layer containing a transparent, molecularly oriented, linear, high molecular weight, hydroxyl-containing vinyl polymer, at least a portion of which has been dyed with a dichroic dye; and a second transparent layer of polyvinyl alcohol, said vinyl polymer-containing layer being water-permeable, the bond formed at the interface of said vinyl polymer layer and said first polyvinyl alcohol layer being capable of being readily broken by water permeating through said laminar structure to said interface of said first polYvinyl alcohol layer and said vinyl polymer layer.

Claim 9

A process as defined in claim 9 wherein said moisture is supplied by said processing fluid, said lamination being effected while said print is still moist from processing.
