Abstract
A cross-linkable coating composition comprising a fluorine-containing elastomeric copolymer which comprises (a) 50 to 95% by mole of repeating units derived from a fluoroolefin of the formula: EQU CF.sub.2 .dbd.CXY (I) wherein X and Y are the same or different and a fluorine atom or a chlorine atom, (b) 50 to 5% by mole of repeating units derived from a perfluorovinyl ether of the formula: EQU R.sub.f --[OCFZCF.sub.2 (CF.sub.2).sub.m ].sub.n --OCF.dbd.CF.sub.2 (II) wherein R.sub.f is a C.sub.1 -C.sub.6 perfluoroalkyl group, Z is a fluorine atom or a trifluoromethyl group, n is an integer of 0 to 5 and m is 0 to 1 provided that when m is 1 (one), X is not a trifluoromethyl group and a cross-linking agent for the copolymer, the copolymer and the cross-linking agent being dissolved or dispersed in a fluorosolvent is provided.
