Abstract

PURPOSE: To confer excellent applicability, e.g., noncoagulating property, noncrystallizability, etc., on pigments, by adding a sulfonic acid compound obtained by the sulfonation of an aromatic polycyclic compound to the pigments.
CONSTITUTION: A sulfonic acid compound of the formula (where Q is an aromatic polycyclic compound), e.g., 2-hydroxy-3-naphthoic acid anilide-4'-sulfonic acid, is usually prepared by hydrolyzing a product obtained by the reaction of an aromatic polycyclic compound with sulfuric acid, fuming sulfuric acid, etc. Then, 0.3W 30pts.wt. sulfonic acid compound is added to 100pts.wt. pigment (e.g., soluble or insoluble azo pigments), and then the pigment composition is added to and dispersed into a nonaqueous vehicle, where the pigment is well dispersed by using a disperser such as dissolver, etc. Thus, a pigment product which has better fluidity due to the lowering of the structural viscosity of dispersion, etc., as well as no problems with color separation, the change of crystal form, etc., and which is capable of forming lustrous and beautiful print or paint, as compared with the case where pigment alone is used, film can be obtained.
