DICHROMATIC RECORDING PAPER

摘要

PURPOSE:To provide a paper capable of drawing a clear dichromatic image with one thermal head by piling a film having an ink layer containing material prone to being a solid at a normal temperature and being a liquid or a sticky body at a high temperature on a thermal paper having a color developing layer different in the hue from the ink and a heat barrier layer in such a manner as to be separable from each other. CONSTITUTION:An ink film 3 in which an ink is mixed with a thermoplastic material (i.g. ester wax) prone to being a solid at a normal temperature and being a liquid or a sticky body at a high temperature is applied on a supoot body 1 (i.g. polyester film) to form an ink layer is piled on a thermal recording paper (i.g. leuco dye) in which a material developing color in the hue different from the ink is applied on a support body 6 (i.g. leuco dye) to form a color developing layer 5 while provided with a heat barrier layer 4 (i.g. resin) having a shielding effect matching the ink surface of the former and the heat barrier layer side of the letter in such a manner as to be separable from each other. Thus, a recording paper is obtained as expected.
