Abstract: Paper, board and cardboard are produced by adding (i) at least one retention aid and (ii) ionic, water-insoluble, uncrosslinked, organic microparticles which have an average particle size of less than 500 nm and a content of polymerized ionic monomers of less than 1% by weight or water-insoluble, uncrosslinked, organic microparticles having an average particle size of less than 500 nm and a content of polymerized ionic monomers of not more than 10% by weight, which are obtainable by polymerizing the monomers in the presence of silica, waterglass, bentonite and/or mixtures thereof, to a paper stock and draining the paper stock over a wire.

Abstract: The invention relates to paper coating slurries containing a mineral pigment and an aqueous polymer dispersion as binding agent. The invention is characterized in that the polymer dispersion is obtained by performing emulsion polymerization of ethylenically unsaturated compounds (monomers) an d in that the paper coating slurry is gelled above 35~ C, i.e. the viscosity o f the paper coating slurry at least doubles at a temperature of between 35 and 60~ C in comparison with the viscosity at 30~ C. The paper coating slurry is particularly suitable for cast-coating, wherein the coating slurry is gelled during the coating process and the coated paper is brought into contact with a metal cylinder.
