Patent ID: 7285372

Claim:
A radiation-sensitive element comprising (a) a substrate with at least one hydrophilic surface and (b) a radiation-sensitive coating on at least one hydrophilic surface of the substrate, wherein the coating comprises: (i) at least one free-radical polymerizable monomer, oligomer, polymer or mixture thereof with at least one ethylenically unsaturated group each, (ii) at least one photoinitiator or sensitizer, which is capable of absorbing radiation of a wavelength in the range of 250 to 1,200 nm, (iii) at least one stabilizer compound comprising at least one group capable of inhibiting free-radical polymerization, and at least one other group capable of sorption at the hydrophilic surface of the substrate, wherein the stabilizer compound is a monomeric compound, and (iv) optionally at least one additive comprising coinitiators which form free radicals after the excitation of the photoinitiator or sensitizer with radiation of a wavelength of 250 to 1,200 nm, binders, dyes, plasticizers, chain transfer agents, leuco dyes, inorganic fillers, surfactants or polymerization inhibitors not suitable for sorption at the surface of the substrate, wherein the at least one group of the stabilizer compound capable of sorption at the surface of the substrate is: wherein R 1 is C 1 -C 18 aralkyl or C 6 -C 10 aryl and X represents a single bond, —O—, —NH— or —N(C 1 -C 10 alkyl)-.
