IMPROVED ABLATION-TRANSFER IMAGING/RECORDING

摘要

A unique method/system for simultaneously creating and transferring a contrasting pattern of intelligence on and from a composite ablation-transfer imaging medium to a receptor element in contiguo us registration therewith is improvedly radiation sensitive and versatile, is kinetically rapid and not dependent on a sensitized ablative topcoat, and is well adapted for such appli- cations as, e.g., color proofing and printing, the security coding of variou s documents and the production of masks for the gra- phic arts and printed circuit industries; the composite ablation-transfer imaging medium, per se, comprises a support substrate (i), at least one intermediate "dynamic release layer" (ii) essentially coextensive therewith and an imaging radiation-ablative carri- er topcoat (iii) also essentially coextensive therewith, said imaging radiation-ablative carrier topcoat (iii) including an imaging amount of a contrast imaging material contained therein, and said at least o ne dynamic release layer (ii) absorbing such imaging radiation at a rate sufficient to effect the imagewise ablation mass transfe r of at least said carrier topcoat (iii).
