PURPOSE:A colored polymer which has a green fluorescence and, when added to a transparent thermoplastic resin, does not affect, especially, transparency, obtained by the homopolymerization of a specified colorant or its copolymer with a vinyl monomer in the presence (absence) of a rubber-like polymer. CONSTITUTION:A colored polymer obtained by homopolymerizing compound A or copolymerizing it with at least one vinyl monomer copolymerizable there with in the presence (absence) of a rubber-like polymer, Said compound A as a colorant is represented by the formula (wherein R1 and R2 are each at least one substituent selected from among H, a 1-4C alkyl, C1 and Br and n is 1-3). Examples of said rubber-like polymers include polybutadience, styrene /butadiene copolymer and polyisoprene. Examples of said vinyl monomers include styrene, alpha-methylstyrene and (meth) acrylic acid compounds. The content of said vinyl monomer component is preferably 0-99.99wt.%. The colored polymer is used independently or as a mixture with another rubber or resin.
