Abstract: Polyurethanes (I) used as coating materials or components for the same are prepared by reacting (1) an isocyanate (II) with a chain extender (V).Compounds (II) are chosen from either : (A) prepolymers prepared by reacting (A1) a polyvalent alcohol (III) containing more than one hydroxyl group which can react with an isocyanate group with (A2) an aliphatic or aromatic polyvalent isocyanate (IV), in which the ratio of reactive hydroxyl groups in (III) to isocyanate groups in (IV) is less than 1 ; or (B) compounds (IV). (V) are prepared by (a) reacting a polyvalent alcohol (VI) with (b1) a compound (VII) containing an epoxy function and a functional group which can react with alcohols, to form a compound (VIII) and then reacting (VIII) with an alpha,beta-olefinic unsaturated carboxylic acid (IX) to form a compound (X), or with (b2) a compound (IX) to form (X) and then (c) reacting (X) with an amine (XI) containing at least one prim. amino group which can react with the alpha,beta- multiple bond in (IX). The sum of the amino and hydroxyl groups in (V) capable of reacting with isocyanate groups is greater than the number of isocyanate groups in (II). Also claimed are (i) the preparation of (I) by the above method, (ii) the use of (I) as coating materials or components for these, (iii) cross-linkable binder systems comprising (I) and a polyvalent isocyanate (XII) in which the ratio of isocyanate groups for (XII) to the groups in (I) reactive towards isocyanate groups is 0.1-2 and (iv) coated articles prepared by applying a layer containing one of these binder systems and then cross-linking.

Abstract: Magnetic recording media, consisting of a non-magnetic base and a magnetic layer firmly bonded thereto, exhibit improved properties in sustained operation if, in the course of their production, a dispersion of inorganic particles in a solvent is applied to the magnetic layer, and the solvent is then removed.
