Reaction Steps

A reactor was charged with 1.4 g of 1, 5-dichloroanthraquinone, 33.6 g. of stearyl amine, 1.3 g of sodium acetate, 0.3 g of copper acetate and 3.2 g of pyridine and the reaction was effected at 80° C. for 15 hours under stirring. The resulting red solid was dissolved in benzene and insoluble matters were removed, followed by distillation of benzene and recystallization from glacial acetic acid. Thus 1, 5-di-n-octadecylaminoanthraquinone was obtained by the reaction of the following formula: ##STR7## Preparation of Liquid Developer:
