    Abstract: A printing plate having a substrate and a radiation sensitive, negative working, organic, polymerizable, photosensitive (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. 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. The 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.

    Abstract: A negative working, radiation imageable plate having an oleophilic resin coating that reacts to radiation by cross linking and is non-ionically adhered to a hydrophilic substrate. The plate is amenable to steps that include imagewise radiation exposing the coating to produce an imaged plate having partially reacted image areas including unreacted coating material, and completely unreacted nonimage areas; developing the plate by removing only the unreacted, nonimage areas from the substrate while retaining unreacted material in the image areas; and blanket exposing the developed plate with a source of energy which further reacts the retained unreacted material in the image areas. A plate with a coating containing resin particles can be imaged to produce initial cross-linking, then mechanically developed. Hardening of the imaged areas is completed with a relatively intense post-heating at 160 deg. C., which further cross links the monomer and fuses the resin particles.
