Abstract

Procedure for preparing suspension of optical brighteners from the group of triazolyl stilbenes, containing 10 to 40% by weight (based on the total weight of the suspension) of a compound of the formula **(See formula)** in which A stands for an aromatic carbocyclic radical containing at most 2 rings and which may be substituted by halogen, alkoxy, sulfo or carboxyl; B means a benzene or naphthalinic radical linked to nitrogen atoms with 2 neighboring carbon atoms and optionally substituted with halogen, alkyl, sulfo or carboxyl; and R stands for sulfo, cyano or hydrogen, characterized in that the wet filter cake obtained in the preparation of said compound is mixed with such an amount of a dispersant that the suspension obtained is thixotropic, does not settle significantly in static storage and has a Brookfield viscosity of 2000 to 10000 centipoise at 6 revolutions per minute, from 1000 to 3500 centipoise at 12 revolutions per minute and up to 2000 centipoise at 60 revolutions per minute.
