Abstract

The coloring matter compound is represented by the following general formula (1):

wherein R 1 , R 2 , R 6 represent an alkyl group; R 3 to R 5 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 to R 3 and R 4 , and R 5 represents an alkyl group; 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 to R 3 to R 5 ; and R 7 , R 8 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 .

First claim

What is claimed is:

1. A coloring matter compound 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 organ…
