Abstract

PURPOSE: To improve the unaggregating, noncrystallizing property, etc. of an offset ink, gravure ink, coating material, etc. in a nonaqueous vehicle, by mixing an azo compound having a specific structure in a pigment.
CONSTITUTION: 100pts.wt. Pigment is mixed with 0.3W30pts.wt. azo compound of formula I [Q is residue of azo dye; A is direct bond, -O-, -NR'-, -S-, -CR'R"-(R' and R" are H, 1W20C alkyl or aryl), etc.; R1 and R2 are H, 1W20C alkyl, aryl or R1 and R2 may form a heterocyclic ring containing N, O or S; n and m are integers 1W4], and the resultant mixture is then dispersed in a nonaqueous vehicle. The azo compound of formula I is obtained by diazotizing an aromatic aimne of formula II (R3 and R4 are H, alkyl, halogen, etc.), and coupling the diazonium compound with a coupler, e.g. phenol.
