    • A colored resin composition using a conventional rhodamine derivative has not provided heat resistance in a practical range. Therefore, it is an object of the present invention to provide a coloring composition having higher heat resistance as compared with the conventional coloring composition. The present invention relates to a compound represented by the following general formula (1), and a polymer having a monomer unit derived from the compound, and the like. (wherein R 1 to R 4 each independently represent a hydrogen atom, an alkyl group, and the like; R 7 represents a hydrogen atom or a methyl group; R 8 and R 9 each independently represent a hydrogen atom or an alkyl group; Y represents a nitrogen atom or a group represented by the following formula (1-1): A 1 represents an alkylene group which has at least one group selected from -O-, -OCO-, -COO-, -NHCO-, -CONH-, -NHCONH- and an arylene group in the chain, and the like; A 2 represents -NH- or -O-; An - represents an anion containing an aryl group having an electron-withdrawing substituent, and the like; n represents an integer of 0 to 3; R 8 and R 9 may form a cyclic structure of a 5 to 6 membered ring together with -N-(CH 2 ) n -Y bonding thereto.)
    • 使用常规罗丹明衍生物的着色树脂组合物在实际范围内不具有耐热性。 因此,本发明的目的是提供与常规着色组合物相比具有较高耐热性的着色组合物。 本发明涉及下述通式(1)所示的化合物和具有来自该化合物的单体单元的聚合物等。 (其中R 1至R 4各自独立地表示氢原子,烷基等; R 7表示氢原子或甲基; R 8和R 9各自独立地表示氢原子或烷基; Y 表示氮原子或由下式(1-1)表示的基团:A 1表示具有选自-O - , - OCO - , - COO - , - NHCO - , - CONH中的至少一个基团的亚烷基 - ,-NHCONH-和链中的亚芳基等; A 2表示-NH-或-O-; An - 表示含有具有吸电子取代基的芳基的阴离子等; n表示具有吸电子取代基的芳基 0至3的整数; R 8和R 9可以与-N((CH 2)n -Y键合在一起形成5至6元环的环状结构)。
