Abstract:
A curable composition, comprising:a compound (A) having at least one active energy ray curable polymerizable functional group, a fluorine-containing copolymer (B) obtained by (1) copolymerizing a polymerizable monomer (a) having a polyfluoroalkyl group and a polymerizable monomer (b) having a photo-curable functional group, or (2) introducing a photo-curable functional group into a fluorine-containing copolymer (D) obtained by copolymerizing a polymerizable monomer (a) having a polyfluoroalkyl group and a polymerizable monomer (d) having a group capable of introducing a photo-curable functional group, and a photopolymerization initiator (C); wherein the polymerizable monomer (a) is a compound of the formula 1: CH2&boxH;CR(CH2)bâ€”Zâ€”Rfâ€ƒâ€ƒFormula 1 wherein R is a hydrogen atom or a C1-4 alkyl group, b is an integer of from 0 to 6, Z is a single bond or a group selected from the group consisting of â€”CH2â€”, â€”Oâ€”, â€”COOâ€”, â€”CONHâ€”, â€”NHCOâ€” and â€”OCOâ€”, and Rf is a C2-40 polyfluoroalkyl group or a C2-40 polyfluoroalkenyl group, provided that at least one hydrogen atom in such a group may be substituted by a hydroxyl group or a halogen atom, and an etheric oxygen atom or a thioetheric sulfur atom may be inserted between a carbon-carbon bond.
