(57) [Problem] To provide a coating agent excellent in heat resistance and flame retardancy. The coating agent comprises a metal-containing ethylenically unsaturated monomer (A) represented by the following general formula (1) and another ethylenically unsaturated monomer (B). Embedded image Wherein, M is a divalent to tetravalent metal, R 1 is a hydrogen atom or a methyl group, m is an integer from 2 to 4, X is -O- (R 2 O) n - , - C O-O- (R 2 O) n-, -CO-O- (R 2 O) n-CO-R 3 -CO-O-, -CH 2 O- (R 2 O) n- or -CH 2 O-CO-R 3 -C N represents an integer of 1 to 8, R 2 represents an alkylene group having 1 to 4 carbon atoms, and R 3 represents an alkylene group having 2 to 4 carbon atoms or an alkenylene group having 2 to 4 carbon atoms. ] |
