Abstract
New Iminoisoindolinone pigments of the formula ##SPC1## Wherein R.sub.1 denotes aromatic radicals, R.sub.2 denotes an H atom, and alkyl group containing 1-6 C atoms, a cycloalkyl group containing 5-6 C atoms or an isocyclic or heterocyclic aromatic radical, X.sub.3 denotes a direct bond or an imino group, the X denote halogen atoms, and Y and Z denote halogen atoms, alkoxy or alkylmercapto groups containing 1-6 C atoms, cycloalkoxy groups containing 5-6 C atoms, aralkoxy, aryloxy or arylmercapto groups, which are useful for pigmenting high molecular organic material.
