    • 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 said at least 2 ink compositions each comprise an aqueous medium, a pigment and a dispersant for dispersing the pigment, and the dispersant is a block copolymer having an A segment that is a hydrophobic segment, a B segment that is an oxyethylene-structure-containing nonionic hydrophilic segment, and a C segment that is an ionic hydrophilic segment. The ratio of the number of unit structures of the A segment to the number of oxyethylene structures contained in the B segment (the number of unit structures of the A segment/the number of oxyethylene structures contained in the B segment) of the block copolymer contained in each of said at least 2 ink compositions is higher in the block copolymer contained in the ink composition having a relatively high solid content concentration than in the block copolymer contained in the ink composition having a relatively low solid content concentration.
