PURPOSE:To obtain an ink film for heat-sensitive recording, capable of preventing the smearing of non-printing area and also of giving clear-cut images by providing a hot-melt type ink layer on a heat-resistant supporter layer with an uneven surface. CONSTITUTION:An uneven surface of a 0.1-micron or more step difference is provided on a heat-resistant supporter layer 1 of polyamide, teflon, etc., and then a hot-melt type ink layer 2 is provided on the uneven surface. Then, a recording medium 4 is placed on the ink layer 2, a thermal head 3 is placed on the back of the supporter layer 1, the head 3 is heated to melt the ink layer 2, the melted ink layer 5 is bonded with the medium 4, the medium 4 is peeled off, and only ink 5 in the melted part is transferred to the medium 4. Thus, sufficiently reproducible images can be obtained even in the thermal head having a 12 numbers/mm. density. |
