Patent ID: 7915320

Claim:
A thermosetting and photocurable coating composition comprising: (A) a hydroxyl-containing resin; (B) a maleimide group-containing copolymer obtained by radical copolymerization of a maleimide group-containing monomer (a) with at least one other monomer, wherein the maleimide group-containing monomer (a) of the copolymer (B) is a maleimide (meth)acrylate represented by formula (4): wherein R 1 and R 2 each independently represent hydrogen or an alkyl group having 4 or less carbon atoms, or R 1 and R 2 may be linked together to form a 5- or 6-membered hydrocarbon ring; R 3 represents an optionally branched alkylene group or optionally branched alkenylene group; R 4 represents hydrogen atom or methyl group; and n is an integer from 1 to 6; (C) a curing agent; and (E) a maleimide compound represented by formula (2): wherein m is an integer from 1 to 6, n is an integer from 1 to 17, and the maleimide compound (E) has a number average molecular weight of 2,000 or less.
