PROBLEM TO BE SOLVED: To provide a copolymer composition in which storage stability of a copolymer having a carboxyl group and an epoxy group in one molecular chain is improved.SOLUTION: The copolymer composition comprises: a copolymer A obtained by polymerizing a polymerizable unsaturated monomer (a1) having an epoxy group, a polymerizable unsaturated monomer (a2) having a carboxyl group, and other polymerizable unsaturated monomer(s) (a3) which can copolymerize; and, as a solvent (B), a cyclic ether compound represented by a formula (1). [In the formula (1), n represents 1 or 2; X represents methylene or an oxygen atom; and R represents a hydrogen atom, a methyl group, or a hydroxymethyl group.]SELECTED DRAWING: None |
