Chlorine-free multifunctional resins for paper finishing
The invention relates to a novel process for the preparation of cellulose-containing material which has been treated and/or sized in order to improve the dry strength and wet strength, characterised in that the cellulose-containing material is treated with a water-dispersible polyisocyanate mixture...
