Procedure

A surface-modified quinacridon colorant was prepared following the procedure of Preparation Example 6, except that hostaperm pink E colorant (colorant red 122) was used instead of phthalocyanine blue. As in Preparation Example 6, the resulting surface-modified coloring colorant was readily dissolved in an aqueous medium by stirring.
