The present invention provides a coloring matter compound excellent in light resistance. The coloring matter compound is represented by the following general formula (1) :
wherein R 1 , R 2 and R 6 each independently represent an alkyl group;
R 3 to R 5 each independently represent an alkyl group, or satisfy either of the following conditions i) and ii) :
i) R 3 and R 4 are bonded to each other, so as to form a cyclic organic functional group containing R 3 , R 4 and a carbon atom bonded simultaneously to R 3 and R 4 , and R 5 represents an alkyl group; and
ii) R 3 to R 5 are bonded to one another, so as to form a cyclic organic functional group containing R 3 , R 4 , R 5 and a carbon atom bonded simultaneously to R 3 to R 5 ; and
R 7 and R 8 each independently represent an alkyl group or an acyl group, or R 7 and R 8 are bonded to each other, so as to form a cyclic organic functional group containing R 7 , R 8 and a nitrogen atom bonded simultaneously to R 7 and R 8 . |
