    摘要: Compounds of the formula ##STR1## wherein R.sup.1 to R.sup.8 each mean, independent from one another, a hydrogen atom or a non chromophoric substituent, R.sup.9 means a hydrogen atom, an alkyl group, a halogen atom, preferably a chlorine or bromine atom, an optionally functionally modified carboxy or sulfo group. They are prepared by reacting 1 mol of 1,7-naphthalene dicarboxylic acid or its acid chloride with 2 mols of an o-aminophenol and subsequent cyclization of the di-N,N'-acyl compounds obtained in the first step. These compounds are valuable optical brighteners.
