The invention relates to compounds of the formula (I) (I) where D1 and D2 are each independently of each other unsubstituted or substituted aryl or hetaryl. The compounds are obtained by diazotizing one or more amines of the formula D-NH2 where D has the meaning D1 or D2 as per the formula (I) and coupling with 0.5 mole of 1,5-diazabicyclo[3.3.0]octane-2,4,6,8-tetrone per mole of total reacting diazonium salts. Depending on the presence and length of alkyl chains the compounds are suitable for use as pigments, disperse dyes or even fat dyes.
