Method for improving the properties of paper or cardboard

摘要

The object of the invention is a method for improving the surface properties of paper and cardboard. In the method, the surface of the paper or the cardboard is treated with a material composition, which contains a binder fraction and a pigment fraction, wherein part of the pigment is formed by an aqueous phase polymerization product of polymerizable monomers and modified starch. The glass transition point (Tg) of the polymer is at least +50 DEG C.
