Abstract
Paper coating compositions with finely divided pigment, optical brightener and a binder containing a copolymer of from 5 to 30% by weight of mono-olefinically unsaturated carboxylic acids, from 5 to 30% by weight of mono-olefinically unsaturated monomers containing basic nitrogen atoms and from 50 to 80% by weight of other olefinically unsaturated monomers which, when polymerized alone, give water-insoluble homopolymers and cause virtually no reduction in the effect of conventional optical brighteners even in the absence of casein or carboxymethyl cellulose.
