Abstract:
1. A pigment dispersion comprising: from 2 to 35% by mass of a pigment (a); from 10 to 30 parts by mass of a polymer (b) with respect to 100 parts by mass of the pigment (a), the polymer (b) comprising (i) 5 to 30% by mass of a repeating unit represented by the following Formula (1), and (ii) a repeating unit derived from N-tertbutylaminoethylmethacrylate, and the polymer (b) having a weight average molecular weight of 10000 to 200000; and from 15 to 50 parts by mass of a graft copolymer (c) comprising a polyalkylene imine chain or a polyallylamine chain in a main chain thereof and a polyester chain in a side chain thereof, with respect to 100 parts by mass of the pigment (a); wherein a total content of the polymer (b) and the graft copolymer (c) is in the range of from 25 to 70 parts by mass with respect to 100 parts by mass of the pigment (a): wherein, in Formula (1), R
