Patent ID: 8455175

Claim:
A photosensitive composition, comprising: a binder polymer prepared by free radical polymerization of acrylic acid and/or methacrylic acid with one or more monomers chosen from acrylate monomers, methacrylate monomers and vinyl aromatic monomers; a free radical polymerizable monomer bearing two or more ethylenically unsaturated groups, a free radical photoinitiator; and a stable free radical inhibitor, wherein the stable free radical inhibitor is present in the composition in an amount of from 0.04 to 0.3 wt % based on the total weight of the composition; wherein the composition has a total solids content of 45 wt % or greater, and wherein the composition is capable of being coated to a dried thickness of greater than 50 microns by spin coating in a single application.
