Abstract: An improved paper coating composition containing, per 100 parts by weight of finely divided pigment, from 5 to 25 parts by weight of a copolymer A having a glass transition temperature of from -40 DEG to +50 DEG C. in the form of an aqueous dispersion and from 0.1 to 10 parts by weight of a high molecular weight polymer B which is obtained by polymerizing water-soluble ethylenically unsaturated monomers in a water-in-oil emulsion. Papers having improved water resistance are obtained.
