Disclosed is a colored resin composition for an optical filter which contains a dye as a colorant and has excellent heat resistance and solubility in a special solvent. The colorant includes a colorant, a solvent for dissolving the colorant, a binder resin, a crosslinkable monomer, and a polymerization initiator for the crosslinkable monomer. The colorant converts tetracyanoborate ions (TCB ions) into anions. A colored resin composition for optical filters, which is a cationic dye. With this colored resin composition, for example, a color filter used in an image display device such as a liquid crystal display device can be produced. [Selection] Figure 1 |
