ABSTRACT:
The present invention provides: a pigment composition that includes at least (A) a polyallylamine derivative including at least 1% to 50% by mol of a structural unit represented by Formula (1-a), 49% to 95% by mol of a structural unit represented by Formula (1-b) and 1% to 30% by mol of a structural unit represented by Formula (1-c), and (B) a pigment, and improves pigment dispersibility and dispersion stability; an ink composition, a printed article and an inkjet recording method, which use the pigment composition; and a polyallylamine derivative useful for these.In Formula (1-b), R1represents —NHCOR3or —NH3+OCOR3, in which R3represents a residue obtained by removing a carboxy group from any one of polyester, polyamide or polyesteramide, which each have a free carboxylic acid. In Formula (1-c), R2represents —NHCOR4or —NH3+OCOR4, in which R4represents an organic group having an aromatic ring or a heteroaromatic ring.
