Abstract
Abstract A dry system for forming and transferring images is provided. The system comprises a photoactive component comprising a tacky photohardenable layer on a selected carrier sheet and a transfer component comprising a frangible color layer on a selected carrier sheet. The two components are disposed with their photohardenable and color layers in air-free contact with one another and then subjected to irradiation with actinic radiation in accordance with a selected image pattern so as to cause selected portions of the photohardenable layer to harden and fuse to confronting portions of the color layer. Then the two components are separated whereby the fused portions of the color layer are separated from its carrier sheet and transferred to the photoactive component. Thereafter the color layer remaining on the transferable component is coated with a pressure-sensitive adhesive. Finally, the transferable component is positioned with its adhesive coating engaging a receptor substrate and the rear side of its carrier sheet is rubbed hard or burnished with a suitable implement so as to cause the remaining image-defining portions of the color layer to separate from its carrier sheet and adhere to the receptor substrate.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
187 words
A dry image reproduction laminate comprising a photoactive component and a transferable component, said photoactive component comprising a first support and a single layer of an unexposed photopolymerizable material on said first support, said first support being capable of transmitting radiant energy at a wavelength at which said energy is capable of initiating a photochemical hardening reaction in said photopolymerizable material, said layer of photopolymerizable material on said first support being tacky, said transferable component comprising a second support, and an adherent colored layer of a frangible non-photopolymerizable material on said second support, said frangible non-photopolymerizable layer comprising at least one polymer binder and at least one wax, said layers of photopolymerizable and frangible non-photopolymerizable materials being in confronting and adhering relation to one another, said layer of unexposed photopolymerizable material having an adhesion to said first support which is greater than the adhesion between said layer of frangible non-photopolymerizable material and said second support, and said photopolymerizable material being capable upon hardening of bonding to said frangible non-photopolymerizable material with an adhesive strength greater than the adhesion between said frangible non-photopolymerizable material and said second support.
Claim 2
Dependent Claim
187 words
A dry image reproduction laminate comprising a photoactive component and a transferable component, said photoactive component comprising a first support and a single layer of an unexposed photopolymerizable material on said first support, said first support being capable of transmitting radiant energy at a wavelength at which said energy is capable of initiating a photochemical hardening reaction in said photopolymerizable material, said layer of photopolymerizable material on said first support being tacky, said transferable component comprising a second support, and an adherent colored layer of a frangible non-photopolymerizable material on said second support, said frangible non-photopolymerizable layer comprising at least one polymer binder and at least one wax, said layers of photopolymerizable and frangible non-photopolymerizable materials being in confronting and adhering relation to one another, said layer of unexposed photopolymerizable material having an adhesion to said first support which is greater than the adhesion between said layer of frangible non-photopolymerizable material and said second support, and said photopolymerizable material being capable upon hardening of bonding to said frangible non-photopolymerizable material with an adhesive strength greater than the adhesion between said frangible non-photopolymerizable material and said second support.
