A water-dispersible urethane acrylate binding agent which comprises a reaction product of: (A) 1 gram equivalent NCO of a di- or tri-isocyanate; (B) from 0 to 0.7 gram equivalent OH of a polyol, free of organically bound sulphur; (C) from 0.1 to 0.7 gram equivalent OH of a hydroxy-(C2-C6 alkyl)-acrylate; and (D) from 0.01 to 0.5 gram equivalent NH of an amino sulphonic acid or an alkali metal or an alkaline earth metal salt thereof having from 1 to 4 amino groups per sulphonic acid group; the ratio of NCO group: NCO-reactive groups being from 1:1 to 1:1.2 which are prepared by reacting components (A), (B), (C), and (D) in a ratio of NCO groups:NCO-reactive groups of from 1:1 to 1:1.2 at a temperature of from 20 DEG to 100 DEG C. The water-dispersible urethane acrylates, hardenable by high energy radiation or ultraviolet light, are particularly suitable in the production of coatings, painting and printing colors and as binding agent in an aqueous dispersion for impregnating textiles and strengthening non-woven fabrics.
