Abstract

PURPOSE: To disperse a pigment so as to exhibit good fluidity in nonaqueous vehicles for offset ink, paints, etc. and give lustrous print and coating films, by adding a specified (substd.) cyclic compd. to a pigment.
CONSTITUTION: A pigment is dispersed by using 0.5W30pts.wt. (per 100pts.wt. said pigment) mono-, di-, tri- or tetra-substituted compd. obtd. by substituting a compd. of formula I (wherein A, B are each CO, NH, N, S, O, CH2, CH) or a mono- or di-substituted compd. of formula I [substituted with one or two substituents selected from halogen, nitro, methoxy, phenoxy, a 1W20C (substd.) alkyl] with one to four substituents selected from a group (A) of formula II [wherein R1, R2 are each a 1W20C (substd.) alkyl], a group (B) of formula III [wherein R3 is H, halogen, nitro, a 1W20C (substd.) alkyl], a group (C) of formula IV [wherein R4 is H, a 1W4C alkyl; R5 is a 1W20C alkylene (substituted with N, O or S); R6, R7 are each H, a 1W20C alkyl], a group (D) of formula V and a group (E) of formula VI (wherein M is an alkali metal or an alkaline earth metal).
