Abstract
Laminar structures comprising a color diffusion transfer photographic print bonded to a vinyl sheet using an adhesive mixture of a vinyl acetate-ethylene copolymer and a hydroxylated polymer, and a method for preparation thereof using an adhesive-supporting carrier sheet.
Claims26
A laminar structure comprising a carrier sheet material supporting on one surface thereof and peelably releasable therefrom a layer of an adhesive mixture consisting essentially of a vinyl acetate-ethylene copolymer and a hydroxylated polymer.
A laminar structure comprising a carrier sheet material supporting on one surface thereof and peelably releasable therefrom a layer of an adhesive mixture comprising a vinyl acetate-ethylene copolymer and a hydroxylated polymer, said layer of adhesive in turn bonded to the image-receiving layer of a color diffusion transfer photographic print.
A laminar structure comprising a transparent layer of a polyvinyl chloride bonded to an adhesive layer consisting essentially of a mixture of a vinyl acetate-ethylene copolymer and a hydroxylated polymer in a weight ratio ranging from about 85/15 to about 95/5, said adhesive layer in turn bonded to the image-receiving layer of a color diffusion transfer photographic print.
A process for preparing an ID card laminar structure comprising:
- applying to a moist image-receiving layer of a color diffusion transfer photographic print a layer of an adhesive mixture comprising a vinyl acetate-ethylene copolymer and a hydroxylated polymer supported on one surface of a carrier sheet;
- allowing sufficient time for the moist adhesive-photographic print bond to dry and then peeling the carrier sheet from the adhesive mixture to leave an adhesive-coated photographic print structure;
- and
- positioning a vinyl protective sheet over the adhesive coated print and heat sealing the vinyl sheet to said print structure to form a secure bond thereto.
