Procedure

Next, copper phthalocyanine (tri- or tetra-) sulfonic acid (tri- or tetra-) sodium salt was gradually fed to chlorosulfonic acid followed by dropping of thionyl chloride to perform reaction. The reaction liquid was cooled and the deposited crystal was filtered to obtain a wet cake of desired copper phthalocyanine (tri- or tetra-) sulfonyl chloride, which was then stirred and suspended followed by addition of aqueous ammonia, and a compound represented by the following chemical formula (γ) to perform reaction. Then, water and sodium chloride were added to the reaction liquid to deposit crystal. The deposited crystal was filtered, washed with an aqueous sodium chloride solution, filtered/washed again, followed by drying to obtain the color material represented by the chemical formula (3).
