The dye alone is excellent in build-up property and relatively strong in light fastness. However, in the accelerated test method using a xenon arc lamp (Toyota method) as an evaluation method of light fastness, the above formula (I) is used.
Changes to reddish, and the formula (II) tends to fade.
In terms of color value, the dye of the formula (I) has a low color value and is about 1/5 of the formula (II), and is economically disadvantageous. Therefore, by mixing and using the dyes of the formulas (I) and (II), not only the disadvantages of both are complemented, but also there is almost no discoloration after irradiation with a xenon arc lamp, and it has excellent light fastness and build-up. It has been found that a good and economical dye composition can be obtained, and the present invention has been completed.
