Pyridone azo compound, tautomer thereof, and colorant-containing curable composition, color filter and manufacturing method thereof

摘要

The invention provides a pyridone azo compound represented by the following Formula (I) R¹, R³ and R⁴ each independently represent a hydrogen atom, an alkyl group having 1 to 21 carbon atoms, an alkenyl group having 2 to 21 carbon atoms, an aryl group having 6 to 21 carbon atoms, an aralkyl group having 7 to 21 carbon atoms, or a substituent having a hetero atom; at least one of R¹, R³ and R⁴ represents a substituent having a hetero atom; R³ and R⁴ may be formed into a heterocycle together with a jointly bonded nitrogen atom; and R² represents an alkyl group having 1 to 10 carbon atoms, a methoxymethyl group, or a trifluoromethyl group. The invention further provides a colorant-containing curable composition and a color filter which contain the pyridone azo compound of Formula (I) and/or a tautomer thereof as a colorant.
