Abstract

Procedure for the preparation of suspensions of optical brighteners from the group of diestilbenes containing 15 to 60% by weight, based on the total weight of the suspension, of a compound of the general formula R1-CH = CH-X-CH = CH-R2 (I) in which X signifies a diphenyl radical linked in position 4 and 4'to the groups = CH-; R1 and R2, independently of one another, signify a benzene, diphenyl, naphthyl or pyridyl radical; and at least one of the cyclic systems R1, R2 and X contains a sulfo group, possibly functionally degraded, a sulfonic group or a nitrile, mercapto or methyl group, characterized by mixing with a dispersant the wet filter cake obtained in the preparation of said compound, so that the resulting suspension is thixotropic, does not settle significantly during static storage and has a Brookfield viscosity of 2000 to 10000 centipoises at 6 rpm and up to 2000 centipoise at 60 rpm.
