Coloring composition, ink for ink jet, and ink jet recording method

摘要

An ink for an ink jet includes a coloring composition comprising a dispersion medium and coloring particulates containing an oil-soluble dye represented by formula (1) and a polymer selected from the group consisting of polyurethanes, polyesters, polyamides, polyureas and polycarbonates. The formula (1) satisfies at least one of following (i) to (v): (i) A represents -NR<4>R<5>, R<4 >and R<5 >each represents independently a C1-18 alkyl group having a substituent group; (ii) At least one of R<2 >and R<7 >represents a substituted alkyl group; (iii) R<8 >represents an aryl group having two or more substituent groups; (iv) Two or more substituent groups represented by -NR<170>SO2R<171 >are present in the molecule; and (v) One or more carboxyl groups are present in the molecule.
