Abstract:
A cured resin obtained by a curing method comprising subjecting, to cationic polymerization or radical polymerization, a curable resin which comprises a copolymer of a monomer (1) represented by the general formula (1) given below, wherein the monomer (1) has two ethylenic groups as shown below, and one or more monomers selected from the group consisting of monomers (2), (3), (5) and (6) respectively represented by the general formulas (2), (3), (5) and (6) given below, wherein the weight ratio of the monomer (1)/sum total of monomers (2), (3), (5) and (6) is 5/95 to 95/5 and the number average molecular weight of said copolymer is 2000 to 1,000,000; in the formula, R1 represents a hydrogen atom or a methyl group, X represents COOR2 or OR2, R2 represents an alkylene group containing 1 to 6 carbon atoms and may optionally be substituted with a hydroxyl group or a halogen atom, and Z represents a propenyl group or an allyl group; in the formula, n is an integer of 1 to 10; in the formula, R1 represents a hydrogen atom or a methyl group, m is an integer of 0 to 6 and n is an integer of 1 to 10; in the formula, R1 represents a hydrogen atom or a methyl group, T represents COOR6 or OR6, and R6 represents a cyclic alkyl or cyclic alkenyl group containing 3 to 15 carbon atoms and may partly be substituted with a hydroxyl group or a halogen atom; in the formula, R1 represents a hydrogen atom or a methyl group, W represents an alkyl group, a hydroxyl group or a halogen atom and k is an integer of 0 to 5, and wherein one of the ethylenic groups in monomer (1) provides for the curing of the copolymer.
