Abstract

L'invention concerne un procédé pour l'amélioration de l'effet des azurants optiques dans l'industrie du papier, caractérisé en ce que l'on met en contact les azurants anioniques classiques utilisés dans l'industrie du papier avec un halogenure de polypipéridine qui est adsorbé à l'état dispersé sur un support en fines particules.The invention relates to a method for improving the effect of optical brighteners in the paper industry, characterized in that the conventional anionic brighteners used in the paper industry are contacted with a polypiperidine halide. which is adsorbed in the dispersed state on a carrier in fine particles.
