ABSTRACT:
Novel dinaphthyl derivatives characterized by the general formula ##SPC1## heterocycle,
Where X.sub.1, X.sub.2, and X.sub.3, X.sub.4 represent a group O=C--Y--C=O, wherein Y is an imino group, either unsubstituted or containing one of the following substituents: alkyl, cycloalkyl, aryl, and neterocycle, either unsubstituted or containing one of the following substituents: amino group, halogen, alkoxy, alkyl; or one X of the pair X.sub.1, X.sub.2 ; and one X of the pair X.sub.3, X.sub.4 represent a group --C=O and then the other X is in the benzimidazole or perinone cycle, the compounds of said formula being either symmetrical or non-symmetrical with respect to the 1,1'-bond.
Said derivatives are produced by reacting 1,1'-dinaphthyl-4,4',5,5',8,8' hexacarboxylic acid with a compound of the general formula R-NH.sub.2, where R is hydrogen, alkyl, cycloalkyl, aryl, or heterocycle, either unsubstituted or containing one of the substituents: amino group, halogen, alkoxy, alkyl, in a solvent or in excess compound of the formula R-NH.sub.2.
Said derivatives are employed for producing perylenetetracarboxylic acid derivatives either in their free form or directly on a textile material in the process of dyeing or textile printing.
