Abstract
A polymer having a structural unit represented by the following Chemical Formula 1, where R1 represents hydrogen or a methyl group, L1 represents —COO—, —CONH—, or a single bond, X represents a hydrocarbon group having 2 to 10 carbon atoms or a hydrocarbon group having 2 to 10 carbon atoms and containing oxygen, L2 represents —O— or —NH—, Y represents a hydrocarbon group having 2 to 12 carbon atoms, and L3 represents —NH—C2H4—R2, —O-Ph-CH2CH(R2)2, or —O—Np—CH2CH(R2)2, where Ph represents a phenylene group, Np represents a naphthylene group, and R2 represents a phosphonic acid group.
