An object of the present invention is to provide a stable blue coloring composition for a color filter which is excellent in color characteristics, heat resistance, light resistance and solvent resistance and does not generate foreign matter on the coating film, and color characteristics using the same. And providing a color filter excellent in heat resistance, light resistance and solvent resistance. A coloring composition for a color filter comprising at least a coloring agent, a binder resin, and an organic solvent, wherein the coloring agent reacts a resin having a cationic group in a side chain with a xanthene acid dye. This is solved by the blue coloring composition for color filters, which contains the obtained salt-forming compound (A) and a blue pigment. [Selection figure] None |
