<p>A colorant composition which comprises a coloring pigment, a pigment-dispersing resin, a water-eliminable resin which, after having been dried at ordinary temperature (25°C), is water-soluble, and water, wherein the pigment-dispersing resin and the eliminable resin both are water-soluble resins, the pigment-dispersing resin comprises a pigment-dispersing resin (A) having an acid value of 110-220, the weight ratio of the coloring pigment (P) to the water-soluble resins (R) consisting of the pigment-dispersing resin (A) and the water-eliminable resin (B), P/R ratio, is from 1/1 to 1/30, the weight ratio of the coloring pigment (P) to the pigment-dispersing resin (A), P/A ratio, is from 10/1 to 1.5/1, and the water-eliminable resin comprises at least 10 wt.% eliminable resin comprising polyvinyl alcohol (PVA) having a degree of saponification of 75-98 mol% and a viscosity of 30.0 mPa·sec or lower (4% aqueous solution; 20°C).</p> |
