Aqueous suspensions of fine-particulate fillers that are at least partially lined with anionic lattices, wherein the suspensions are obtained from the treatment of aqueous suspensions of fine-particulate fillers with at least one anionic latex having a glass transition temperature of -5 to -50°C, preparation of the aqueous suspensions and use thereof as additives to paper materials in the production of paper containing fillers, carton containing fillers or corrugated cardboard containing fillers by de-watering the paper materials. L'invention concerne des suspensions aqueuses de fines matières de charge, recouvertes au moins partiellement de micelles anioniques, ces suspensions étant obtenues par traitement de suspensions aqueuses de fines matières de charge au moyen d'au moins un latex anionique présentant une température de transition vitreuse de -5 à -50°C. L'invention porte également sur la production de ces suspensions aqueuses et sur leur utilisation comme additif à la pâte à papier lors de la production de papier, de carton ou de carton-pâte, contenant tous des matières de charge, par égouttage de la pâte à papier.
