New intermolecular salts of dyestuffs - with acid and aliphatic basic gps. have equal numbers of acid and basic gps. in the mol., useful for colouring plastics

摘要

New intermolecular salts (I) of dyestuffs with acid and aliphatic basic gps. have equal numbers of acid and basic gps. in the mol. Am-F-Bn (I). The prepn. of (I) is claimed. - (IA) are prepd. by reacting a component contg. m A gps. with a component contg. n B gps., one component contg. the F gp. or both components contg. a precursor of F.
