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
<p>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.</p>
