New Dyes from Naphthostyril-5-carboxylic Acid: Synthesis of 6,12-Anthanthrenedione-3,4,9,10-tetracarboxylic Diimides, Naphthostyril-5,6-dicarboximides and 1-Amino-4-arylaminonaphthalene-5,8-dicarboxylic Bislactams

The novel vat dyes 6,12-anthanthrenedione-3,4,9,10-tetracarboxylic diimides (XIa-c) and the disperse dyes, naphthostyril-5,6-dicarboximides (XVIIIa-f) and bislactams (XIXa-d) have been synthesised from a common intermediate, naphthostyril-5-carboxylic acid (V).An improved method has also been developed for the synthesis of V.
