Abstract
The present invention is to provide a colorant dispersion liquid which is able to form a high-luminance coating film having better heat resistance compared to the case of using conventional dyes. Disclosed is a colorant dispersion liquid containing (A) a colorant, (B) a dispersant, and (C) a solvent, wherein the colorant (A) contains a color material represented by the following general formula (I) and a xanthene-based dye; a solubility of the color material in the solvent (C) and that of the xanthene-based dye in the solvent (C) are each 0.2 (g/100 g solvent) or less at 23° C.; and the color material and the xanthene-based dye are dispersed in the solvent (C) by the dispersant (B):(The symbols in the formula are as described in the Description.)
