| 摘要 |
The present invention addresses the problem of providing a colored composition having higher heat resistance compared with conventional colored compositions. The present invention relates to: "a polymer having a monomer unit derived from a monomer which has both (i) a cationic rhodamine derivative having, as an counter anion, an anion containing an aryl group having an electron-withdrawing substituent and an anion group and (ii) an ethylenically unsaturated bond"; "a monomer which has both (i) a cationic rhodamine derivative having, as an counter anion, an anion containing an aryl group having an electron-withdrawing substituent and an anion group and (ii) an ethylenically unsaturated bond"; "a colored composition containing the polymer or the monomer"; and "a colored composition for a color filter, which contains the polymer or the monomer". |
