Abstract
Abstract A fluoroalkyl acrylate copolymer comprising recurring units of the general formula (I): wherein R, is hydrogen atom or methyl group. R 2 is a bivalent hydrocarbon group and Rf is a C 2 to C 6 straight or branched perfluoroalkyl group or a C 2 to C 6 straight or branched fluoroalkyl group having hydrogen atoms of not less than one and of not more than half of the number of the carbon atoms, and recurring units of the general formula (II): wherein R 3 is hydrogen atom or methyl group and R 4 is a bivalent hydrocarbon group or a mono-substituted bivalent hydrocarbon group with hydroxyl group or a halogen except fluorine. The copolymer is curable with light and energy rays, and is suitable as a material sensitive thereto for use in resist, dry lithographic printing plate and paint.
