ABSTRACT:
To quench the fluorescence generated by anionic optical brighteners, virtually colourless, water-soluble, cationic compounds are used which contain at least one cationic group per molecule or per repeating structural unit and at least two nitro group-free naphthalene-peridicarboxylic acid imide groups per molecule or at least one such group per repeating structural unit.
