ABSTRACT:
Compounds of the formula ##STR1## and the corresponding lower alkyl quaternary salts thereof in which A represents a group of the formula ##STR2## and in which R.sup.1 stands for a group of the formula ##STR3## whereby R represents a hydrogen atom or a lower alkyl group, R.sup.2 has the same meaning as R.sup.1 or stands for a hydrogen atom or a group of the formula ##STR4## whereby the aromatic rings may be substituted by non-chromophoric substituents. Due to their good fluorescence these compounds can be used as optical brighteners for organic materials, especially textile materials.
