Abstract
A photosensitive ceramic coating composition which is fireable in a substantially nonoxidizing atmosphere comprising an admixture of: PA1 (a) finely divided particles of ceramic solids, PA1 (b) finely divided particles of an inorganic binder dispersed in an organic medium comprising PA1 (c) an organic polymeric binder, and PA1 (d) a photoinitiation system, dissolved in PA1 (e) photohardenable monomer, and PA1 (f) an organic medium wherein the improvement comprises an organic polymeric binder containing a copolymer or interpolymer of a C.sub.1 -C.sub.10 alkyl acrylate, C.sub.1 -C.sub.10 methacrylate, styrene, and an ethylenically unsaturated carboxylic acid, wherein a moiety in the binder derived from the unsaturated carboxylic acid comprises from 5 to less than 15 weight percent of the polymer and wherein the binder has a molecular weight not greater than 100,000 and wherein the composition upon imagewise exposure to actinic radiation is developable in an organic solvent-water mixture.
