Abstract
Abstract A radiation-hardenable binder comprising a reaction product ester containing hydroxyl groups and hydroxyalkyl acrylates, which comprises: (A) 1 NCO gram equivalent of a polyisocyanate containing from 2 to 3 isocyanate groups per molecule; (B) from 0.4 to 1.2 OH gram equivalents of an ethylenically-unsaturated partial ester having an OH number of from 80 to 150 of an alkoxylated trimethylol propane having a degree of alkoxylation of 3 to 4.5 and acrylic acid or methacrylic acid or a mixture thereof; and (C) from 0 to 0.6 OH gram equivalents of a hydroxy alkyl acrylate or hydroxy alkyl methacrylate or a mixture thereof containing from 2 to 6 carbon atoms in the alkyl group, wherein the sum total of the OH-gram equivalents of B and C is between 1 and 1.2. Aqueous dispersions containing the binder are used for impregnating, coating, reinforcing or priming textile materials, wood, plastics, non-wovens or leather.
