An encapsulated colorant including a colorant and a polymer resin coating the colorant, where the polymer resin is prepared by polymerizing a polymer resin-forming composition including two or more polymerizable unsaturated monomers, and the content ratio of the two or more polymerizable unsaturated monomers is controlled to obtain a glass transition temperature of the polymer resin of −15 to 75° C. An ink composition including an encapsulated colorant, and an ink set comprising two or more types of the ink composition. The encapsulated colorant may have different glass transition temperatures to have a utility of high optical density when printing text, and high gloss when printing images.
