ABSTRACT:
The invention relates to a method for preventing the brightening effect of an optical brightening agent on a textile substrate comprising applying on the textile substrate a water-soluble, cationic, optical brightener quencher either before or together with a resin precursor and submitting the treated substrate to a heat treatment. This method imparts an antibrightening effect to goods when they are washed with an optical brightener containing detergent.
