Abstract:
Aqueous slurries of finely divided fillers which are at least partly covered by anionic latices, the slurries being obtainable by treating aqueous slurries of finely divided fillers with at least one anionic latex which comprises, incorporated in the form of polymerized units, at least one monomer comprising phosphonic and/or phosphoric acid groups, preparation of the aqueous slurries and their use as an additive to the paper stock in the production of filler-containing paper, filler-containing cardboard or filler-containing board by draining the paper stock.
