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, 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 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.
