Beschreibung
Zusammenfassung:	The invention relates to magnetic recording media, consisting of a nonmagnetic substrate and at least one magnetisable layer firmly applied thereon and based on a polyurethane binder, the binder consisting of at least 50% by weight of a high molecular weight branched polyurethane elastomer having OH-containing urea groups at the chain ends, and in which the sliding properties are improved and the friction is reduced by incorporating siloxane groups.
