Abstract

Binders for papercoating slips which permit uniform printability contain a polymer prepared by the seed procedure and comprising PA1 from 1 to 49% by weight of a polymer seed A) having a glass transition temperature of from -80.degree. to +25.degree. C. and based on esters of acrylic acid or methacrylic acid, and PA1 from 51 to 99% by weight of ethylenically unsaturated monomers B), from 10 to 100% by weight of which monomers are butadiene, the polymer seed A being added before or during the polymerization of the ethylenically unsaturated monomers.
