摘要：
The invention relates to the putilization, in a method for making a paper sheet and as an agent retarding the penetration of a coating mixture in said sheet, of an aqueous dispersion and/or solution of mineral materials, characterised in that it contains at least one water-soluble copolymer that comprises at least one ethylenically unsaturated anionic monomer and at least one ethylenically unsaturated oxialkyl monomer and ends by a hydrophobic chain. The invention also relates to a method for making a paper sheet using said copolymer, and a to the paper sheet thus obtained.
