Abstract (en)
[origin: ES488597A1] An improved paper-coating composition which contains, per 100 parts by weight of a finely divided pigment, from 5 to 25 parts by weight of a copolymer A, in the form of an aqueous dispersion, as a binder, and from 0.5 to 10 parts by weight of a copolymer B, containing (a) from 20 to 70% by weight of copolymerized units of hydroxy-C2-C4-alkyl acrylates or hydroxy-C2-C4-alkyl methacrylates, (b) from 10 to 50% by weight of copolymerized units of acrylic acid, methacrylic acid, maleic acid and/or monoesters of maleic acid and (c) from 5 to 50% by weight of copolymerized units of acrylonitrile, methacrylonitrile, C1-C4-alkyl acrylates of C1-C4-alkyl methacrylates, or vinyl esters of saturated C2-C4-carboxylic acids as the co-binder, with or without from 0.1 to 2.0 parts by weight of an optical brightener which is activated by the co-binder. The paper-coating composition has high water retention.
