<p>An aqueous paper-coating composition which essentially comprises a finely divided pigment and an emulsion copolymer of (a) from 30 to 80% by weight of C4-C8-alkyl acrylates or mixtures of C4-C8-alkyl acrylates and di-(C4-C8-alkyl) maleates, (b) from 8 to 30% by weight of acrylic acid and/or methacrylic acid, (c) from 0 to 50% by weight of vinyl propionate, vinyl acetate, methyl acrylate, ethyl acrylate and/or vinyl alpha -branched C10-monocarboxylate, (d) from 0 to 5% by weight of acrylamide, methacrylamide, vinylsulfonic acid, 2-acrylamido-2-methylpropanesulfonic acid and/or acrylonitrile and (e) from 0 to 3% by weight of crosslinking monomers in the form of an aqueous dispersion, as the sole binder and thickener.</p> |
