| 摘要 |
The present invention is to provide a colored composition having higher heat resistance compared with conventional colored compositions. The present invention further relates to: "a polymer having a monomer unit derived from a monomer which has (i) a cationic rhodamine derivative having, as an counter anion, an anion including an aryl group having an electron-withdrawing substituent and an anion group and (ii) an ethylenically unsaturated bond", "a monomer which has (i) a cationic rhodamine derivative having, as an counter anion, an anion including an aryl group having an electron-withdrawing substituent and an anion group and (ii) an ethylenically unsaturated bond", "a colored composition comprising the above-described polymer or the monomer", and "a colored composition for a color filter comprising the above-described polymer or the monomer". |
