Abstract
A novel compound suitable for use as an ultraviolet absorber is provided. Further provided are a resin composition and a coating material each containing the novel compound. A bis(benzotriazolyl phenol) compound represented by the following general formula (1), a resin composition containing the compound, and an ultraviolet-absorbing polymer prepared by copolymerization of the compound: [wherein A represents a methylene group, a (CH3)2C group or a C2H5(CH3)C group; R1 and R6, either identical to or different from each other, represent a hydrogen atom, an alkyl group having 1-4 carbon atoms, an aryl group, an alkoxy group having 1-4 carbon atoms or a halogen atom; R2 and R4, either identical to or different from each other, represent a straight-chain or branched alkylene group having 1-6 carbon atoms; R3 and R5each represents a hydrogen atom or a methyl group; and 1, m and n each indicates 0 or 1].
