Ink set for use in ink-jet recording, image forming process and image recording apparatus |
摘要 |
Disclosed herein is an ink set for use in ink-jet recording, which comprises at least 2 ink compositions the solid content concentrations of which are different by more than 2% by mass. The at least 2 ink compositions each comprise an aqueous medium, a pigment and a dispersant for dispersing the pigment. The dispersant is an amphiphilic block copolymer having an A segment that is a hydrophobic segment, a B segment that is a nonionic hydrophilic segment, and a C segment that is an ionic hydrophilic segment. The number of unit structures of the B segment of the amphiphilic block copolymer contained in each of the at least 2 ink compositions is smaller in the amphiphilic block copolymer contained in the ink composition having a relatively high solid content concentration than in the amphiphilic block copolymer contained in the ink composition having a relatively low solid content concentration.
