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.
