Claims Analysis

Total Claims: 33
Claim 1
Independent Claim 189 words
A heat-sensitive transfer medium for use in a printing method in which a heat transfer layer, provided on one surface of a support, is brought into contact with a receiving medium and localized areas of in ink layer are heated by means of a thermal head which is brought into contact with the other surface of the support, thereby transferring the heating areas of the transfer layer onto a receiving medium thereby forming printed images thereon, said transfer medium comprising a support and a transfer layer comprising at least a non-flowable, opaque ink layer, a metal deposition layer and an adhesive layer, said three layers being provided in that order from the support side of the medium, said transfer layer being capable of being transferred onto a receiving medium so that the localized areas of said layer that are heated by means of a thermal head are selectively transferred to form non-metallic printed images on the receiving medium said ink layer comprising a resin and a coloring agent and being substantially non-flowable under the transfer conditions, said metal deposition layer acting as a shading layer in the printed images.
