PIGMENT DISPERSION, AQUEOUS PIGMENT DISPERSION LIQUID AND INK FOR INKJET RECORDING

摘要

A pigment dispersion of the present invention includes a bisacetoacetarylide pigment (a); a styrene-acrylic acid-based copolymer (b); a basic compound (c); and a wetting agent (d), wherein the wetting agent (d) includes a diol compound (e), the diol compound (e) is a compound represented by a general formula (1) or a general formula (2), and
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒA-B€ƒ€ƒ€ƒ€ƒ€ƒ(1)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒC-O-D€ƒ€ƒ€ƒ€ƒ€ƒ(2)
the mass ratio (e) / (a) of the diol compound (e) and the bisacetoacetarylide pigment (a) is within a range from 3/100 to 15/100.
