摘要：
A colorant for ink-jet printing ink, having an average particle diameter of 0.001 to 0.15 µm, and comprising: extender pigments as core particles; a gluing agent coating layer formed on at least a part of the surface of said core particle; and an organic pigment coat uniformly formed on at least a part of said gluing agent coating layer. The colorant for ink-jet printing ink exhibits not only a high tinting strength and a clear hue, but also excellent dispersibility and light resistance in spite of fine particles.
