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

)
n
—Y— bonding thereto.)
使用传统的罗丹明衍生物的有色树脂组合物在实际范围内未提供耐热性。因此,本发明的目的是提供一种比传统着色组合物具有更高耐热性的着色组合物。本发明涉及由以下通式(1)所代表的化合物,以及具有源自该化合物的单体单位的聚合物等。(其中R1至R4分别独立地代表氢原子、烷基基团等;R7代表氢原子或甲基基团;R8和R9分别独立地代表氢原子或烷基基团;Y代表氮原子或由以下式(1-1)所代表的基团:A1代表在链中至少具有一种从—O—,—OCO—,—COO—,—NHCO—,—CONH—,—NHCONH—和芳基基团中选择的基团的亚烷基基团等;A2代表—NH—或—O—;An−代表含有具有电子吸引取代基的芳基团的阴离子等;n表示0至3的整数;R8和R9可以与结合其的—N—(CH2)n—Y—共同形成5至6元环的环状结构。)
