Abstract
A polycarbonate resin of a copolymer of diethyleneglycol bis(allyl carbonate) with one of glycidyl acrylate and glycidyl methacrylate, its homopolymer and its copolymer, and further occasionally a copolymerizable compound can be easily modified with active amine at its surface, and the surface-modified copolymer of diethylene glycol bis(allyl carbonate) with glycidyl acrylate or methacrylate can be easily dyed with acid dye in a sharp color tone and can be used in an optical instrument demanded to have a high vividness of color.
