ABSTRACT:
When diazotizing a benzanilide of the formula ##STR1## wherein R is chloro, methyl or methoxy and X is carbamoyl or acetamino, or, when R is chloro or methyl, X is also methyl or chloro, and coupling it onto 5-acetoacetylaminobenzimidazolone-(2), monoazo pigments are obtained which are useful for coloring plastics and lacquers. The pigments have a very good fastness to light, solvents, over-lacquering, bleeding and a high heat resistance.
