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.degree. 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.
