A multi-layered article comprising a first layer of a thermoset polyurethane. A second layer of a polymeric composition is bonded to the first layer. The polyurethane has available isocyanate groups prior to the application of the second layer. The second layer is applied onto the first layer in a pre-polymeric or polymeric state wherein the material has carboxyl groups and a cross-linking agent.

A multi-layered article comprising a first layer of a thermoset polyurethane. A second layer of a polymeric composition is bonded to the first layer. The polyurethane has available isocyanate groups prior to the application of the second layer. The second layer is applied onto the first layer in a pre-polymeric or polymeric state wherein the material has carboxyl groups and a cross-linking agent. about 2 to about 6, that of the transverse stretching being set to a value in the range from about 2 to about 5, and that of any second longitudinal stretching carried out being set to a value in the range from about 1.1 to about 3, and in which thereafter heat setting of the film is carried out at oven temperatures of from about 200 to about 260° C. and the film is then cooled and rolled up, wherein the rolled-up film is then wade up on a make-up machine at speeds in the range from about 300 to about 400 m/min and wherein the make-up procedure is carried out using winding tensions in the range of 90 N/m to 200 N/m and contact pressures in such a way that the contact pressure is set in the range from about 300 N/m to about 350 N/m. 2. The film support as claimed in claim 1, wherein its electrostatic charge build-up is in the range from about -70 kV/m to about +70 kV/m, the contact pressure of the roll cutters during make-up being in the range from about 310 N/m to about 340 N/m. 3. A magnetic tape comprising the film support as claimed in claim 1, and a coating of a magnetic recording media thereon, said coating having a laser defect rate of ≤2% after coating with magnetic recording medium. 4. The film support as claimed in claim 1, being multilayered. 5. The film support as claimed in claim 1, which essentially comprises a crystallizable polyester having an RSV value in the range from about 0.4 to about 1.0 dl/g, which is a polycondensate, selected from the group consisting of polyethylene terephthalate, polybutylene terephthalate, poly-1,4-cyclohexylenedimethylene terephthalate, polyethylene 2,6-naphthalenedicarboxylate, polyethylene naphthalate/bibenzoate, polyethylene p-hydroxybenzoate or mixtures of these. 6. The film support as claimed in claim 1, which contains further additives in amounts in the range from about 0.1 to about 20% by weight, the additives being selected from the group consisting of inorganic organic pigments, stabilizers, antioxidants, antiblocking agents or mixtures of these. 7. The process as claimed in claim 1, wherein the film is drawn between electrical discharge means along the film path in the make-up machine. 8. The process as claimed in claim 7, wherein the electrical discharge means are arranged close to the roll and wherein the discharge means are discharge rods.
