PROBLEM TO BE SOLVED: To provide a heat-sensitive magnetic recording material wherein adhesiveness and solvent resistance of logotype printing parts are reinforced and in addition, sharp letter informations is provided and a logotype printing ink with no side effect such as deterioration of magnetic characteristics is used. SOLUTION: A heat-sensitive magnetic recording body has a magnetic recording layer wherein a magnetic body, a water-soluble dispersant and a binder are main ingredients on one face of a substrate and has a heat-sensitive recording layer contg. ordinarily a colorless or light-colored leuco dye and an acidic substance as color developing ingredients or a heat-transfer ink receiving layer contg. an inorg. filler, a water-soluble resin and a binder resin and a protective layer provided if necessary, and contg. a water-soluble resin as a main ingredient on another face of this substrate, and a logotype printing layer wherein an inorg. pigment and a vinyl chloride/vinyl acetate copolymer are main ingredients is provided on the magnetic recording layer. |
