[Problem] To provide a cyclocarbonate group-containing (meth)acrylate monomer which can be stably used for a long period of time due to suppressed thickening over time, when a cyclocarbonate group-containing (meth)acrylate monomer is made into a polymer and used in a coating material, etc. [Solution] Provided is a (A) cyclocarbonate group-containing (meth)acrylate monomer represented by formula (1), wherein the content of a (B) di(meth)acrylate monomer represented by formula (2) is at most 3% by weight. Formula (1) (R1 represents a hydrogen atom or a methyl group, R2 represents a C2-C10 alkyl group, and X is 0 or 1.) Formula (2) (R3 represents a hydrogen atom or a methyl group, R4 represents a C2-C10 alkyl group, and X is 0 or 1.) |
