摘要： The invention relates to a polyurethane comprising at least one anionic active group L. The anionic active group L is bound to a segment G in the polyurethane, said segment containing monomers that have been linked by radical polymerisation. The invention also relates to a binding agent composition containing an inventive polyurethane, to a method for the production thereof and to the use of polyurethanes of this type for producing magnetic recording media.
