The invention relates to: a color correction material containing at least one type of cyanine compound composed of a cyanine cation represented by general formula (I) below (wherein the symbols are as defined in the description) and a q-valent anion represented by pAn q- (wherein the symbols are as defined in the description), and at least one type of layered clay mineral; or a color correction material containing a clay mineral composite obtained by intercalating a cyanine cation represented by general formula (I) below, or preferably the cyanine cation and an organic cation, into a layered clay mineral. The invention also relates to a film-forming composition containing the color correction material and an optical filter having a layer composed of the film-forming composition.
wherein: ring A represents a benzene ring or a naphthalene ring; X represents CR 3 R 4 , NR 5 , an oxygen atom, a sulfur atom, or a selenium atom;
R 1 , R 2 , R 3 , R 4 , and R 5 each independently represent a group represented by general formula (II) or (II'), an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 30 carbon atoms, or an arylalkyl group having 7 to 30 carbon atoms;
R 6 , R 7 , R 8 , and R 9 each independently represent a hydrogen atom, a group represented by general formula (II) or (II'), an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 30 carbon atoms, an arylalkyl group having 7 to 30 carbon atoms, a halogen atom, or a cyano group;
Y 1 and Y 2 each independently represent an alkyl group having 1 to 20 carbon atoms, an aryl group having 6 to 30 carbon atoms, an arylalkyl group having 7 to 30 carbon atoms, or a group represented by general formula (III);
Z represents a hydrogen atom, a halogen atom, or a cyano group. |
