Abstract: PROBLEM TO BE SOLVED: To obtain high wear-resistant properties and magnetic properties by providing a layer containing respectively specific rates of a polymer with a specific melt point or a softening temperature and a polymer with a specific minimum melt point or a specific minimum softening temperature, and also providing another layer containing another polymer on a base. SOLUTION: A base II and a layer III containing 75-90wt.% of a polymer IV with a melt point or a softening temperature of 100-160 deg.C and 10-25wt.% of a polymer V with a melt point or a softening temperature of minimum 90 deg.C are provided on a medium I. In addition, another layer VI containing polymer VII is provided. A monomer accounting for the most part of the polymer IV is an olefinic unsaturated hydrocarbon and the polymer V is polyurethane polyacrylate, polymethcrylate, polyacrylamide or vinyl polymer. The content of the polymer VII is upto 100wt.% for the layer VI and the polymer VII is polyacrylate, polymethacrylate, polyacrylamide or vinyl polymer.

Abstract: Media (I) suitable for thermal transfer, containing (a) a base layer (II), (b) a layer (III) containing (1) 75-90 wt% polymer (IV) with a m.pt. or softening pt. (s.pt.) of 100-160 degrees C and (2) 10-25 wt% polymer (V) with a melting point or softening point of at least 90 degrees C, and (c) a layer (VI) containing a polymer (VII). Also claimed are (i) media (XI) made up of layers, obtained by reacting a medium (I) with a substrate (XII) by bringing the two into contact so that layers (III) and (VI) are between layer (II) and substrate (XII); (ii) a process for the production of media (XI) by contacting (I) with (XII) as above at 80-180 degrees C.
