View Patent ↗The present invention provides a colorant-containing curable composition comprising a colorant, wherein the colorant contains a compound represented by the following Formula (I). In Formula (I), R 1 and R 2 each independently represent H, an alkyl group, an alkenyl group, an aryl group, or an aralkyl group. R 1 and R 2 may be formed into a heterocycle together with a jointly bonded nitrogen atom. R 3 represents a halogen atom, a trihalomethyl group, an alkoxy group, a nitro group, or an amino group. n represents an integer of 0 to 4. R 4 represents a halogen atom or a —SO 3 M group, in which M represents H, a cation of a metallic atom, or a cation consisting of a nitrogen-containing compound. m represents an integer of 0 to 5. The present invention further provides a color filter comprising the compound represented by Formula (I) and a method for manufacturing the color filter.
