Beschreibung
Zusammenfassung:	Perylenetetracarbimide mixed crystal pigments having the crystal lattice of the alpha -modification of bis-N,N'-3',5'-dimethylphenyl- perylenetetracarbimide of the formula (1) and consisting of 99 - 70 mole per cent of the symmetrical diimide of the formula (1) and correspondingly 1 - 30 mole per cent of the asymmetrically substituted diimide of the formula (2) are useful for colouring organic polymers.g
