| 发明名称 | Ink composition and ink jet recording method | ||
| 摘要 | An ink composition contains a pigment, first wax particles, second wax particles, and a resin emulsion, in which the first wax particles have a melting point of 120° C. or higher and 170° C. or lower, the second wax particles have a melting point of 70° C. or higher and less than 120° C., the resin emulsion has a glass transition point of 50° C. or higher and 150° C. or lower, the first wax particles contain one or more kinds of wax particles selected from the group consisting of polyethylene wax particles or polypropylene wax particles, and the second wax particles contain one or more kinds of wax particles selected from the group consisting of polyethylene wax particles. | ||
