| 发明名称 | Ink composition, ink set, and image forming method | ||
| 摘要 | An ink composition of the present invention includes: cross-linked particles containing a quinacridone solid solution pigment including at least two types of quinacridone-based compound; a water-soluble polymerizable compound; a polymerization initiator; and water. By selectively using cross-linked solid solution pigments as pigments (colorants), along with excellent adhesion of the image, the stability over time of the ink composition itself is excellent. | ||

| 主权项 | 1. An ink composition comprising: cross-linked particles in which at least a part of a quinacridone solid solution pigment including at least two types of quinacridone-based compound is coated with a cross-linked resin; a water-soluble polymerizable compound; a polymerization initiator; and water, wherein the ratio of the cross-linked particles (q) and the polymerizable compound (p) [q:p[mass ratio]] is 1:1 to 1:20. | ||
