Abstract:
A process for laminating an ink jet print comprising:a) providing an ink jet print comprising a support having thereon an ink jet image in an ink jet image-receiving layer; b) contacting the imaged surface of the ink jet print with a transfer laminating element to form a composite, the transfer laminating element comprising a flexible, polymeric support having thereon a protection layer of a water-dispersible, hydrophobic polyester resin having the following general formula: In-P-Am â€ƒwherein I is an ionic group; n is an integer from 1-3; P is a polyester backbone; A is an aliphatic group comprising a straight or branched chain fatty acid or triglyceride thereof having from about 6 to about 24 carbon atoms; and m is an integer from 3-8, c) applying heat and pressure to the composite to transfer the layer on top of the ink jet image; d) allowing the composite to cool; and e) peeling the flexible, polymeric support of the transfer laminating element from the composite to form the laminated ink jet print which has better water and stain resistance than said ink jet print which is unlaminated.
