    摘要： The invention consists of the use, within a method for manufacturing a paper coating, as a thickening agent of said coating, of a water-soluble polymer characterized in that it is made up of at least one ethylenically-unsaturated anionic monomer, of at least one ethylenically-unsaturated oxyalkylated monomer terminated by a branched hydrophobic alkyl, alkylaryl, arylalkyl, or aryl chain having 14 to 24 carbon atoms, and possessing 2 branches having at least 6 carbon atoms. The water retention of said coating is thereby improved, which contributes to a better printability of the paper coated by said coating.

    摘要： The invention concerns a process to manufacture paper coatings containing at least one mineral matter, at least one binder and water, characterised in that at least one comb polymer obtained by grafting of a least one polyalkylene oxide function on to the polymer chain, where the said chain results from the polymerisation of a least one ethylenic unsaturated monomer, is introduced into the above-mentioned composition.The paper coatings thus obtained have increased water retention and reduced Brookfield viscosity compared to the same coatings containing a water-retaining thickening agent of the prior art.
