ABSTRACT:
When diazotizing a benzanilide of the formula ##STR1## wherein R is methoxy and X is carbamoyl or acetamino and coupling it onto 5-acetoacetylaminobenzimidazolone-(2), a monoazo pigment is obtained having the formula ##STR2## wherein R is methoxy and X is carbamoyl or acetamino. The monoazo pigments are effective for coloring plastics and lacquers and exhibit a very good fastness to light, solvents, over-lacquering, bleeding and have a high heat resistance.
