Description of the Related Art In the conventional printing method, it takes too much time to print, and it is not possible to print at the same time in the field where a prepaid card is used. In some cases, white ink is printed on the black layer of magnetic powder for printing, but there is no simple printer that can be used on site. In addition, although there are some examples using a heat-sensitive dye, there is a problem in practical use in terms of weather resistance. As a technique relating to thermal recording, Japanese Patent Application Laid-Open No. 1-1

候性、耐久性に優れているという利点を有している。The black layer containing titanium black is whitened by returning from titanium black to titanium oxide at a temperature of 300 ° C. or higher, but this change progresses more rapidly than melting and scraping a low melting metal silver color layer such as Sn. And again-
It is possible to print with excellent black-white visibility as compared with black-based printing. This printing is done with a normal thermal head (surface temperature 50
(0 to 600 ° C.) or laser light heating can be performed at high speed and clearly. The change from titanium black to white titanium oxide is irreversible, and the characters once printed cannot be restored, which is excellent in terms of security. In addition, titanium black is stable up to 200 ° C, does not change in color tone due to humidity, etc., and does not undergo deterioration due to pressure, so it is superior in weather resistance and durability to the case of using a heat-sensitive dye. have.
