WIPO Patent Application WO/2018/062475

A1

A copolymer composition containing: 100 parts by mass of a copolymer that has structural units derived from a monomer represented by formula (1) and structural units derived from another radical polymerizable monomer, the copolymer containing 0.5-6.0% by mass of phosphorus atoms derived from the monomer represented by formula (1); and 0.01-7.0 parts by mass of a compound represented by formula (2). (In formula (1), R1 represents a hydrogen atom or a methyl group, R2 represents a C1-4 alkylene group, and R3 and R4 each independently represent a hydrogen atom or a C1-10 alkyl group.)
