Abstract:
The invention consists in the use, in a method for manufacturing a sheet of paper, of an aqueous suspension and/or dispersion of mineral materials as an agent for slowing the penetration of the paper coating into said sheet, characterized in that said suspension and/or dispersion contains at least one water-soluble copolymer made up of at least one ethylenically-unsaturated anionic monomer, and at least one ethylenically-unsaturated oxylalkylated monomer terminated by a hydrophobic chain.It also consists in a method for manufacturing a sheet of paper which implements said copolymer, as well as the sheet of paper obtained.
