Paper coating slips contain an emulsion copolymer, comprising overall from 0 to 60% by weight of a vinylaromatic, from 40 to 95% by weight of a C.sub.1 -C.sub.10 -alkyl (meth)acrylate, from 5 to 40% by weight of an alkenylnitrile, from 0 to 10% by weight of an ethylenically unsaturated acid and from 0 to 20% by weight of further monomers as a binder, wherein the emulsion copolymer is a mixture of at least two polymers or an emulsion copolymer comprising at least two stages, one polymer or one stage whose content in the emulsion copolymer is from 10 to 75% by weight containing at least 90% by weight of the total amount of alkenylnitrile (alkenylnitrile-rich polymer or stage).
A paper coated with a dried coating of an aqueous coating slip composition containing pigments and an emulsion copolymer as binder for said pigments, said copolymer comprising
A paper coated with a dried coating of an aqueous coating slip composition containing pigments selected from the group consisting of barium sulfate, calcium carbonate, calcium sulfoaluminate, kaolin, talc, titanium dioxide, zinc oxide, chalk and coating clay, and an emulsion copolymer as binder for said pigments, said copolymer being unable to undergo crosslinking via double bonds and comprising
