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, R1represents a hydrogen atom or a methyl group,Y2represents -O- or -NR10-, where R10represents a hydrogen atom or an alkyl group,A1represents 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} .
