Abstract

In order to increase the dry strength of paper without at the same time significantly increasing its wet strength, paper is surface-sized with an aqueous solution of an alkali metal salt and/or an alkaline earth metal salt of a copolymer of a) from 90 to 30% by weight of acrylic acid and/or methacrylic acid, and b) from 10 to 70% by weight of acrylonitrile, methacrylonitrile, acrylamide and/or methacrylamide, with or without c) up to 30% by weight of an ester of acrylic acid and/or an ester of methacrylic acid, the copolymer having a viscosity of from 5 to 100 mPas in 2% by weight strength aqueous solution at 20 DEG C, measured in a Brookfield viscometer at 20 revolutions per minute.
