Patent ID: 8343707

Claim:
A printing plate having a photosensitive (PS) coating to be radiation imaged and developed for printing on a lithographic press, comprising: a substrate with a grained, anodized, hydrophilic surface; and a radiation sensitive, negative working, organic, polymerizable PS resin coating non-ionically adhered to the substrate such that the cohesion of the PS coating exceeds the adhesion of the PS coating to the substrate; wherein the PS coating contains active components that participate in radiation induced polymerization, all of which active components are soluble in non-aqueous solvents and none of which active components are soluble or dispersible in any of the group of fluids consisting of water, fountain solution, ink, and press ink; and wherein said PS coating has sufficient cohesion and surface tack to adhere to and be mechanically pulled off the substrate by press ink as particulates without dissolution or dispersion into the press ink.
