Patent ID: 6964993

Claim:
A paper coating slip, comprising: a) from 1 to 40 parts by weight of a binder, b) from 1 to 10 parts by weight of a thickener, the parts by weight of components (a) and (b) based on the solids contents of components a) and b), wherein a PVA dispersed polymer prepared by copolymerizing at least 20% by wt of at least one main monomer selected from the group consisting of C 1-16 -alkyl (meth)acrylates, a vinyl aromatic compound of up to 20 carbon atoms, vinyl esters of carboxylic acids of 1 to 20 carbon atoms, a vinyl halide, an ethylenically unsaturated nitrile, a non-aromatic hydrocarbon of one or two double bonds and mixtures thereof, in the presence of 0.5 to 250 parts by weight of polyvinyl alcohol, based on 100 parts by weight of monomer polymerized, is a component of binder a) or thickener b), c) from 0.1 to 5 parts by weight of a fluorescent or phosphorescent dye, and d) one or more pigments, fillers or combinations thereof to complete the composition with the total amounts of components a) to c) based on 100 parts by weight of component d).
