ABSTRACT:
Perylene-3,4,9,10-tetracarboxylic acid diimides of the formula I ##STR1## in which R is a linar or branched alkylene, alkylenecycloalkylene or cycloalkylenealkylene radical which has at least 15 C atoms and which is interrupted by one or two --COO--, --OOC--, --CONH-- and/or --NHCO-- groups, and Z is hydrogen, hydroxyl or a --COOH group.
Perylene diimides of this type are exellently suitable for coloring polyolefins. In this regard, they are particularly distinguished by their low tendency to bloom. They are also very suitable for coloring engineering plastics, in which they produce fluoroescent colorations having a high fluoroescence and excellent fatness to heat, light and weathering.
