An object of the present invention is to provide a water-insoluble coloring matter compound having high solubility for a solvent and high lightness and chroma and providing a chromaticity closer to the magenta chromaticity represented by the Adobe RGB color space. A water-insoluble coloring matter compound represented by the formula (1) is provided: Formula (1) wherein R1 and R2 represent an alkyl group, and R3 represents an alkyl group, an aryl group, or an alkoxy group. And the alkyl group, the aryl group and the alkoxy group regarding to R1 to R3 are capable of having a substituent.
