Abstract

Novel sizing compositions, their preparation and use. The compositions contain water-dispersible and/or water-soluble and alkylamine-blocked polyisocyanates, film-forming resins, coupling agents and lubricants. The isocyanates are synthesized from at least one polyisocyanate, at least one ionic and/or potentially ionic and/or nonionic compound, and at least one blocking agent which is at least 20% by weight aralkylamines.
