Abstract: A radiation-curable aqueous binder dispersion which comprises water and, dispersed therein, one or more prepolymers which contain from 0.01 to 1.0 mole of polymerizable carbon-carbon double bonds per 100 g of prepolymer and have a mean molecular weight of not less than 350 and a viscosity at 23 DEG C. of not less than 600 cp, as well as from 0.1 to 30 percent by weight, based on prepolymer, of one or more dispersants and from 0 to 20 percent by weight, based on prepolymer, of one or more photoinitiators. The binder dispersions according to the invention may be used as surface coatings for non-metallic and metallic substrates, and for bonding fiber webs.
