ABSTRACT:
A laser addressable thermal imaging element comprising a bleachable photothermal converting dye in association with a heat-sensitive imaging medium, and a photoreducing agent for said dye, said photoreducing agent bleaching said dye on laser address of the element. The imaging element may be in the form of a colorant transfer system, a peel-apart system, a phototackification system or a unimolecular thermal fragmentation system. Also provided is a method of crosslinking a resin by leaser irradiation, which is useful in the production of colored images.
