Zusammenfassung:	PURPOSE: A colorant composition can form a coloring layer combining high heat resistance and solvent resistance, thereby being suitable for manufacturing various color filters. CONSTITUTION: A colorant composition contains a coloring agent including a lake pigment, a dispersing agent, and a crosslinking agent. The dispersant contains a copolymer with a repeating unit which has an oxygen-containing saturated heterocyclic group or contains both of a dispersant with a urethane group and a (meth)acrylic dispersant (except for the copolymer). A pigment-dispersed solution contains a lake pigment, a copolymer including a repeating unit having an oxygen-containing saturated heterocyclic group, and a solvent.
