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。
