Abstract
1,245,478. Benzoxanthene - dicarboxylic acid imide dyestuffs. FARBWERKE HOECHST A.G. 1 Nov., 1968 [2 Nov., 1967; 6 July, 1968], No. 51963/68. Heading C4P. [Also in Division C2] Novel dyestuffs of the formula (wherein R is H, or optionally substituted alkyl, cycloalkyl or aryl, or OH, NH 2 or a heterocycle; and R 1 and R 2 are each H, halogen, CN, alkoxycarbonyl, alkyl, alkoxy or aryl) are prepared (1) by heating the diazonium salt of a compound of the formula (wherein one of X 1 and X 2 is NH 2 and the other is H) at 60‹ to 100‹ C. in the presence of copper or a copper salt; or (2) by carrying out the same process on a corresponding naphthalic acid or its anhydride and condensing the product with ammonia or the appropriate amine RNH 2 at about 100‹ to 200‹ C. The water-insoluble dyestuffs yield yellowish-green fluorescent dyeings, and are particularly suited for the colouring in the mass of synthetic polymers and for dyeing fibrous materials from polyethylene terephthalate and acetyl cellulose.
