<P>PROBLEM TO BE SOLVED: To provide a colorant composition for a color filter, which excels in discoloration resistance. <P>SOLUTION: A colorant composition for a color filter includes a phthalocyanine compound having a maximum absorption wavelength λmax of 600 to 700 nm, a yellow dye compound, and a dispersant having an amine value of 5 to 150 mgKOH/g. The content of the dispersant is 5 to 30 pts.mass with respect to the total 100 pts.mass of the phthalocyanine compound and the yellow dye compound, and the discoloration resistance ΔAbs of the colorant composition is 0.2 to 1.3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
