Abstract: 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 which is optionally crosslinked with polyisocyanate, the binder consisting of at least 50% by weight of a low molecular weight branched polyureaurethane having OH-containing groups at the chain ends, and in which the sliding properties are improved and the friction is reduced by incorporating siloxanes.

Abstract: 1. A process for preparing an ester of acrylic or methacrylic acid with a hydroxyl-containing organic compound, which comprises esterifying a saturated polyester which contains no fewer than 2 free hydroxyl groups per molecule and may contain ether groups or a saturated polyether which contains no fewer than 2 free hydroxyl groups per molecule, this polyester or polyether having an average molecular weight ~Mn of from 400 to 4,000, with from 100 to 150 mol %, based on the OH groups of the polyester or polyether, of acrylic acid or methacrylic acid in the presence of an acidic esterification catalyst and one or more hydrocarbons forming an azeotropic mixture with water and a small amount of a polymerization inhibitor at elevated temperature with azeotropic removal of the resulting water, after the esterification removing the hydrocarbon by distillation and after neutralization of the esterification catalyst reacting the remaining acrylic or methacrylic acid with an amount, equivalent to the acid number, of an epoxy compound having no fewer than two epoxy groups per molecule until an acid number =
