<p><P>PROBLEM TO BE SOLVED: To provide a colorant composition having excellent mounting properties without problems such as bleeding when coated on paper and without flowing out a pigment even when spraying water after drying and easily erasable when applied to a fiber aggregate such as a cloth or a nonwoven fabric by simple washing with a weakly alkaline synthetic detergent. <P>SOLUTION: The colorant composition is characterized as follows. The colorant composition comprises at least a color pigment P, a water-soluble resin R and water. The water-soluble resin R is composed of a water-soluble resin A and an anionic resin B. The color pigment P is dispersed with the water-soluble resin A. The acid value of the anionic resin B is≤110 and the weight ratio (P/R ratio) of the color pigment P to the water-soluble resin R is (1/1) to (1/30). The weight ratio (P/A ratio) of the color pigment P to the resin A is (10/1) to (1.5/1). The weight ratio (A/B) of the resin A to the resin B is 0.02-1.2. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
