Colorant-containing curable composition, color filter and method of producing the same

摘要

The present invention provides colorant-containing curable composition including a colorant of a metal salt having a di-valence or higher valence. The colorant is preferably a colorant of the compound represented by the following formula (I): wherein R<1 >represents a hydrogen atom, an alkyl group having 1 to 21 carbon atoms, an alkoxy group having 1 to 21 carbon atoms, or an electron-attractive group; R<2 >represents a cation having a charge equal to 1 valence of a cation of a metal atom having a valence of at least 2; and n represents an integer from 0 to 5.
