Abstract
Abstract Disclosed is a curable composition consisting essentially of (i) a polymerizable double bond-containing resin prepared by introducing a polymerizable double bond-containing group into a polymer containing as a monomer a fluoroalkyl acrylate or methacrylate represented by the formula CH.sub.2 ═C(R)--COO(CX.sub.2).sub.m (CF.sub.2).sub.n X (I) wherein R is methyl or hydrogen, X is fluorine or hydrogen, m is 1 or 2 and n is an integer of 1 to 12, and (ii) a fluoroalkyl acrylate or methacrylate of the formula (I).
