  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。）

  Provided are: a graft polymer and a colored resin that are free from color migration or fading caused by bleed-out after coloring, which is a defect of a dye, without impairing vivid color development and transparency of the dye; a method for producing the same; and a resin composition containing the colored resin. The present invention relates to: (1) a graft polymer that has a polyolefin (A) as the main chain, and a polymer (B) polymerized a dye (b) having a radical reactive functional group, in a side chain; (2) the graft polymer which is characterized in that the dye (b) having the radical reactive functional group is a cationic rhodamine derivative, a cationic triarylmethane-type dye derivative or a cationic cyanine-type dye derivative, having an ethylenically unsaturated group; (3) a colored resin consisting of the graft polymer; as well as (4) a method for producing the colored resin, which is characterized by mixing the polyolefin (A), the dye (b) having the radical reactive functional group, and the radical reaction initiator (C), and subjecting a radical reaction of the mixture; and the like.

  本发明提供了：一种接枝聚合物和有色树脂，它们在不损害染料的鲜艳显色性和透明性的情况下，不会因着色后的渗色（染料的缺陷）而导致颜色迁移或褪色；一种生产方法；以及一种含有该有色树脂的树脂组合物。 本发明涉及(1)一种接枝聚合物，其主链为聚烯烃(A)，侧链为聚合了具有自由基活性官能团的染料(b)的聚合物(B)；(2)该接枝聚合物，其特征在于具有自由基活性官能团的染料(b)是阳离子罗丹明衍生物、阳离子三芳基甲烷型染料衍生物或阳离子氰基型染料衍生物，具有乙烯不饱和基团；(3) 由接枝聚合物组成的有色树脂；以及 (4) 生产有色树脂的方法，其特征在于将聚烯烃 (A)、具有自由基活性官能团的染料 (b) 和自由基反应引发剂 (C) 混合，并使混合物发生自由基反应；等等。
