Abstract
Media I suitable for the thermal transfer of a layer contain a) a substrate II, b) a layer III thereon, containing 1) from 75 to 90% by weight of a polymer IV having a softening point of from 100 to 160.degree. C., and 2) from 10 to 25% by weight of a polymer V having a softening point of at least 90.degree. C. and c) a layer VI containing a polymer VII.
Claims7
A medium suitable for the thermal transfer of a layer which contains
- a) a substrate,
- b) a first transferable layer directly thereon, consisting essentially of
- 1) from 75 to 90% by weight of a polymer of polyolefinic hydrocarbons having a melting point or softening point of from 100 to 160.degree. C., and
- 2) from 10 to 25% by weight of a polymer selected from the group consisting of phenoxy resins and epoxy resins having a melting point or softening point of at least 90.degree. C.
- and thereon
- c) a second transferable layer consisting essentially of a polymer selected from the group consisting of polyacrylates, polymethacrylates, polyacrylamide, vinyl polymers, cellulose-containing binders, phenoxy resins and epoxy resins and polyurethanes and a ferromagnetic pigment.
