The present invention addresses the problem of providing a colored dispersion which is extremely lowly odorous. The colored dispersion comprises a dispersant comprising a compound represented by formula (1), a water-insoluble colorant, and water, the compound giving an aqueous solution thereof having a solid concentration of 30 mass%, the aqueous solution having a 1-methylnaphthalene content of 50 ppm or less and a 2-methylnaphthalene content of 50 ppm or less. (In formula (1), R1 and R2 each independently represent an alkyl group having 1-8 carbon atoms, n is an integer of 1-500, and the M moieties each independently represent a hydrogen atom, a metal ion, or an ammonium ion.) |
