Abstract
Magnetic recording media comprise a non-magnetic base and one or more magnetic layers consisting of an organic binder matrix containing finely divided magnetic material, the said binder matrix being obtained by electron beam curing of a mixture of from 60 to 100% by weight of a polyurethane acrylate polymer possessing polymerizable acrylate double bonds and from 0 to 40% by weight of an acrylate monomer and/or an acrylate prepolymer and/or an N-vinyl monomer.
