Abstract
Aqueous dispersions of mixtures of (a) polyurethanes having hydrophilic groups which result in water dispersibility of the polyurethane and (b) radiation-curable (meth)acrylate prepolymers which are dilutable in at least 5% by weight of water, such as hydroxyl-containing polyether acrylates, are suitable, owing to their penetration behavior and their high solids absorption in paper, for use as radiation-curable coating or impregnating materials for paper substrates.
