【Task】 The object of the present invention is to provide a stable blue coloring composition for a color filter having excellent color characteristics and heat resistance, light resistance, and solvent resistance, and color characteristics using the same, and to provide heat resistance, light resistance, and solvent resistance. It is to provide an excellent color filter. A blue coloring composition for a color filter containing a colorant (A), a pigment derivative (B), a resin (C), and a solvent, wherein the colorant (A) is triarylmethane. A basic dye forming salt compound (A1) and a blue pigment (A2), and the pigment derivative (B) includes a pigment derivative (B1) having an acidic group having a copper phthalocyanine structure or a dioxazine structure as a base skeleton. This is solved by the blue coloring composition for a color filter. [Selection figure] None |
