Beschreibung
Zusammenfassung:	The invention relates to a magnetic recording support made of a non-magnetic support material which is provided with a magnetic layer, essentially consisting of a dispersion of an anisotropic magnetic material in a polyurethane binder mixture which is crosslinked with polyisocyanate, and in which the polyurethane binder mixture consists of a low-molecular weight polyurea urethane containing OH groups and a high-molecular weight thermoplastic linear polyurethane in a mixing ratio of 9:1 to 1:9.
