Abstract: The invention relates to a method for producing the quaterrylene-3,4:13,14-tetracarboxy diimides of general formula (I), wherein R, R' independently represent hydrogen or optionally substituted C1-C30 alkyl, C3-C8 cycloalkyl or aryl or hetaryl. The inventive method is characterized by reacting the perylene-3,4-dicarboximide of the general formula (IIa) in the presence of a base resistant, high-boiling, organic solvent and an alkali-containing or alkaline earth-containing base with the perylene-3,4-dicarboximide of the general formula (IIb), wherein X represents hydrogen, bromine or chlorine.
