Abstract: A paper coating slip containing a mineral pigment and an aqueous polymer dispersion as a binder, wherein the polymer dispersion is obtainable by emulsion polymerization of ethylenically unsaturated compounds (monomers) and the paper coating slip gels at above 35° C., i.e. the viscosity of the paper coating slip at from 35 to 60° C. is at least twice the viscosity at 30° C.

Abstract: The addition of a (co)polymer B, comprising an N-vinylcarboxamide, to a polymer dispersion, the bonding force of this binder in a paper coating composition is increased, and the optical brightener in the paper coating composition is extremely strongly activated. Polymer dispersions containing: (i) a (co) polymer A with at least one main monomer selected from 1-20C alkyl (meth)acrylate, vinyl ester from up to 20C carboxylic acid, up to 20C vinyl aromatics, ethylenically unsaturated nitrile, vinyl halide, vinyl ether or 1-10C allyl ethers containing alcohols and aliphatic 2-8C hydrocarbons and 1 or two double bonds included by polymerization (sic); and (ii) at least one N-vinylcarboxyic acid amide in polymerized form containing (co)polymer B. Independent claims are included for: (1) a paper coating composition containing the polymer dispersion; and (2) a process for preparation of the polymer dispersion by mixing a dispersion of (co)polymer A with (co)polymer B, its dispersion, solution, suspension, or emulsion, and a brightener, its solution, or suspension.

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.
