Title: Thermal recording medium
Inventor: TOYAMA KOJI
IPC: B41M5/30
Filed: 1990-07-02
Abstract: PURPOSE:To ensure that a sheet is not contaminated by waste from a thermal head and is also not fouled in stripes by the pressing force of the thermal head, if printed using a serial print-type thermal printer by adding specific paraffin wax to a thermal coloring layer and limiting the dynamic friction factor of the thermal coloring layer to 0.3 or less. CONSTITUTION:A thermal recording medium consists of a thermal coloring layer containing leuco dye and a developer, on the one surface of a support. In this medium, the thermal coloring layer contains paraffin wax with a melting point of 70 deg.C or higher and a blocking temperature of 60 deg.C, and has a dynamic friction factor of 0.3 or less on the surface. This paraffin wax has a pressure coloring effect as does the ordinary paraffinx wax and also has a melting point of 70 deg.C or higher and a blocking temperature of 60 deg.C or higher. Subsequently, it has a significant coloring prevention effect on the color development by the heat accumulation of a thermal head. Further, it is possible to completely prevent waste from sticking to the surface of the thermal head by adjusting the composition ratio of the thermal recording layer and thereby reducing the dynamic friction factor of the surface of the thermal recording layer to 0.3 or less.
