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.
