摘要: The invention concerns the use of a water-soluble or water-dispersible polymer having a molecular weight of at least 800, containing at least 5 aldehyde groups per molecule and at least 1 carboxyl group per molecule, the ratio of aldehyde groups to carboxyl groups being higher than 0.75:1, as a wet strength additive. The invention also discloses novel cationic derivatives thereof.

摘要: Tissue paper having a bulk between 2 and 8 cm3/g and containing an amount of a wet strength agent, wherein the tissue paper contains a wet strength agent in the form of a nitrogen-containing polymer having hydrophobic side-chains. Said tissue paper before converting has a relative wet strength value (RWS) of at least 45%.
