Summary:PURPOSE:To obtain a pigment compsn. which gives a gravure ink improved in souring resistance. CONSTITUTION:A diazo component formed by diazotizing an arom. amine having a sol. group is coupled with a coupler component comprising beta- hydroxynaphthoic acid or beta-naphthol and converted into a calcium lake simultaneously with or after the coupling, giving a monoazo lake pigment. The objective compsn. is prepd. by adding a powdered aluminum salt of rosin to this pigment.
