Abstract
Compounds of the formula I ##STR1## wherein the symbols Z, R.sub.1, R.sub.2, m and n have the meanings defined in claim 1, are suitable, as high-grade pigments, for dyeing high-molecular organic material. They are characterized in particular by good fastness to migration and to cross-lacquering, as well as to weather and light.
