Abstract

Iminoisoindolinone dyestuffs of the formula ##STR1## wherein X is halogen, Y halogen, alkoxy, cycloalkoxy, aralkoxy or aryloxy, Y.sub.1 hydrogen, halogen, alkyl or alkoxy having 1 - 4 c-atoms, Y.sub.2 alkyl, alkoxy or alkanoylamino having 1 - 4 c-atoms or benzoylamino, Z chlorine or methyl and R alkyl having 1 - 4 c-atoms or aryl which are useful for pigmenting high molecular organic material. It has been found that new, valuable iminoisindolinone dyestuffs of the formula ##STR2## wherein the X denote halogen atoms, especially chlorine atoms, Y denotes a halogen atom or an alkoxy, cycloalkoxy, aralkoxy or aryloxy group, Y.sub.1 denotes a hydrogen or halogen atom or an alkyl or alkoxy group containing 1 - 4 carbon atoms, Y.sub.2 denotes an alkyl, alkoxy or alkanoylamino group containing 1 - 4 carbon atoms or a benzoylamino group which is optionally substituted, for example by halogen atoms or alkyl or alkoxy groups containing 1 - 4 carbon atoms, the Z denote chlorine atoms or methyl groups and R denotes an alkyl group containing 1 -4 carbon atoms or an aryl radical, preferably a phenyl radical which is optionally substituted by halogen atoms, or alkyl or alkoxy groups containing 1 -…
