Abstract: A UV-curable binder composition, a coating material which contains such a binder composition, a photoiniator mixture suitable for use in these coating materials, and a magnetic recording medium which contains such a UV-curable coating material are described.

Abstract: Media I suitable for the thermal transfer of a layer containa) a substrate II,b) a layer III thereon, containing1) from 75 to 90% by weight of a polymer IV having a softening point of from 100 to 160.degree. C., and2) from 10 to 25% by weight of a polymer V having a softening point of at least 90.degree. C.andc) a layer VI containing a polymer VII.

Abstract: The heat sealing film and a magnetic transfer strip contain an adhesive layer comprising thermoplastic, immiscible binder components. One component is spherical, amorphous and embedded in finely distributed form in a homogeneous layer of the other, highly crystalline components in such a way that the spherical component protrudes hemispherically from the layer. The spherical binder is a glassy solid up to at least 60.degree. C. and above 80.degree. C. is plastically deformable. The hemispheres protruding from the adhesive layer produce a uniform, fine roughness of the surface. Both heat sealing film and magnetic transfer strip are nonblocking up to at least 60.degree. C. and heat-sealable at temperatures greater than 80.degree. C. The adhesive layer imparts to a magnetic recording medium a uniform thickness of the adhesive joint and a permanent, temperature-resistant adhesive force.
