  Provided is an aqueous dispersion of colored particles suitable for colorants for writing instrument inks, inkjet inks, painting materials, aqueous coatings, and the like. The aqueous dispersion of colored particles includes a polymer having at least a unit of a monomer derived from a dye having a polymerizable unsaturated group. The monomer derived from the dye is preferably derived from the compound represented by General Formula (1) below: where Dye represents a dye residue, R 1 represents a hydrogen atom or a methyl group, Y 2 represents —O— or —NR 10 —, where R 10 represents a hydrogen atom or an alkyl group, A 1 represents an alkylene group which is unsubstituted or substituted by at least one group selected from —OCO—, —COO—, —NHCONH—, and the like in the chain thereof and/or at the terminal thereof, and/or a hydroxy group.

  提供一种适用于书写工具墨水、喷墨墨水、绘画材料、水性涂料等颜色颜料的水性彩色颗粒分散液。彩色颗粒的水性分散液包括至少具有源自具有可聚合不饱和基团的染料的单体的聚合物。源自染料的单体最好源自下面的一般式（1）所表示的化合物：其中Dye代表染料残基，R1代表氢原子或甲基基团，Y2代表—O—或—NR10—，其中R10代表氢原子或烷基基团，A1代表未经取代或通过至少选择自—OCO—、—COO—、—NHCONH—等群之一取代的烷基基团以及/或在链中和/或末端具有一个羟基的亚烷基基团。

  Provided is an aqueous dispersion of colored particles being excellent in water resistance and light resistance, which is suitable for colorants for writing instrument inks, inkjet inks, painting materials, aqueous coatings, and the like. The aqueous dispersion of colored particls includes a polymer having at least a unit of a monomer derived from a dye having a polymerizable unsaturated group. The monomer derived from the dye is preferably derived from the compound represented by General Formula (1) below: where Dye represents a dye residue, R1 represents a hydrogen atom or a methyl group, Y2 represents -O- or -NR10-, where R10 represents a hydrogen atom or an alkyl group, A1 represents an alkylene group having at least one group selected from -OCO-, -COO-, -NHCONH-, and the like in the chain thereof and/or at the terminal thereof; an alkylene group having at least one group selected from -OCO-, -COO-, and -NHCONH- in the chain thereof and/or at the terminal thereof, and also has a hydroxy group as a substituent; an alkylene group which has a hydroxy group as a substituent; or an alkylene group} .

  本发明提供了一种耐水性和耐光性极佳的有色微粒水性分散体，它适用于书写工具墨水、喷墨墨水、绘画材料、水性涂料等的着色剂。有色微粒的水性分散体包括一种聚合物，其中至少有一个单元的单体来自具有可聚合不饱和基团的染料。衍生自染料的单体最好衍生自下式（1）所代表的化合物： 其中染料代表染料残基，R1 代表氢原子或甲基、 Y2 代表-O-或-NR10-，其中 R10 代表氢原子或烷基、 A1 代表亚烷基，其链上和/或其末端至少有一个选自-OCO-、-COO-、-NHCONH-等的基团；亚烷基，其链上和/或其末端至少有一个选自-OCO-、-COO-和-NHCONH-的基团，同时具有羟基作为取代基；具有羟基作为取代基的亚烷基；或亚烷基}。
