ABSTRACT:
A photothermal-tackifiable composition, useful as a coating on a substrate, consisting of an optically clear blend of two or more polymers, one or more of which is capable of undergoing a thermochemical reaction, and a photothermosensitive compound, an infrared absorbing dye that generates locally high heat on exposure to infrared or near-infrared radiation, is disclosed. Also disclosed is a process for coating such a composition on a support, exposing the composition to infrared radiation and toning the imagewise exposed composition A "peel-apart" embodiment is also disclosed.
