    • Monoazo pigments of the formula ##STR1## wherein R.sub.1 denotes a H atom, an alkyl group containing 1-4 C atoms or an aryl radical, R.sub.2 denotes a H atom, an alkyl group containing 1-4 C atoms, or an aralkyl or aryl radical, or wherein the radicals R.sub.1 and R.sub.2, conjointly with the N atom, form a heterocyclic 5-membered or 6-membered ring, R.sub.3 denotes an H atom or halogen atom or an alkyl group containing 1-4 C atoms, R.sub.4 and R.sub.5 denote H atoms, alkyl groups containing 1-4 C atoms or phenyl groups optionally substituted by halogen atoms and alkyl and alkoxy groups containing 1-4 C atoms, X denotes an O atom or an imino group, Y denotes an O atom or S atom or an imino group, and Z denotes a halogen atom, an alkyl or alkoxy group containing 1-4 C atoms, or an aryloxy group, and wherein the carbonamide group is located in the m- or p-position to the azo group are prepared. The compounds are useful for coloring high molecular organic materials such as aminoplast, alkyl resins, polystyrene and polyvinyl chloride. The pigments show very good fastness to light and migration.
