  • Patent number: 7276548
    Abstract: 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), R1 and R2 each independently represent H, an alkyl group, an alkenyl group, an aryl group, or an aralkyl group. R1 and R2 may be formed into a heterocycle together with a jointly bonded nitrogen atom. R3 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. R4 represents a halogen atom or a —SO3M 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.
