Abstract

275,609. I. G. Farbenindustrie Akt.- Ges. Aug. 9, 1926, [Convention date]. Triarylmethane dyes. - The residue of a 4- alkoxydiphenylamine is introduced into a triarylmethane dyestuff as one of the aryl groups. According to one example, 4-methoxydiphenylamine is condensed with 4: 4<1>-tetramethyldiaminobenzophenone by means of phosphorus oxychloride and the resulting basic dyestuff is sulphonated in the usual manner. In a second example, Guinea green 2G is heated with 4- amino-1-ethoxybenzene as described in German Specification 287,003 in the presence of hydrochloric acid. The dyestuffs dye wool in a feebly acid bath clear blue tints of pronounced fastness to light.
