The graft copolymer comprises a polymerizable monomer (A1) represented by general formula (III) and a polymerizable monomer (B1) containing a pyridyl group, and a ligand can be bonded via the functional group at the terminus of R 3a . (III) (In the formula, R 1a represents a polymerizable group, R 2a represents an alkylene group with carbon number 2-5, R 3a represents an organic group having at the terminus a functional group selected from among an azi group, a phenyl azi group, a carboxyl group, a primary to quaternary amino group, an acetal group, an aldehyde group, a thiol group, a disulfide group, an active ester group, a trialkoxysilyl group, and a polymerizable group, and n represents any integer from 5 to 20,000.) |
