性が要求されている。The surface of the magnetic recording layer of magnetic recording paper has a color tone such as brownish-brown or dark black because the color tone of the magnetic paint is applied to the original paper, and it is not possible to print visible information on it, so it is not used. Therefore, the necessary visible information is printed on the opposite side of the magnetic recording layer using a normal printing method, a carbon thermal transfer method, a chelate layer, a heat-sensitive recording layer, etc., using a chelate printing method or a heat-sensitive recording method. In actual circumstances, conventionally,
Printing on the surface of the magnetic recording layer has not been given equal consideration and is left in limbo. On the other hand, magnetic recording paper is required to have smoothness without space loss due to contact with a magnetic head.

せたものである。As a result of studying the possibility of printing visible information on the magnetic recording layer, the present invention has been developed to hide the brown color of the magnetic recording layer by simply providing an aluminum coating layer and a pigment coating layer with a relatively small coating amount. Moreover, they found that it has excellent smoothness, does not impede magnetic properties, and has no problem with ticket issuing tests assuming vending machines.

徴とする磁気感熱記録紙である。That is, in the present invention, one side of a base paper is coated with a heat-sensitive paint containing a color-forming leuco dye, a color developer that causes the color-forming leuco dye to develop color when heated, and an adhesive, and a heat-sensitive recording layer is provided. The other side of the base paper is coated with a magnetic paint containing magnetic powder and adhesive as main components to form a magnetic recording layer, and then a magnetic recording layer is formed on the magnetic recording layer. A water-based aluminum paint is coated to form an aluminum coating layer, and a water-based pigment paint containing pigment and adhesive as main components is further applied on the aluminum coating layer to form a pigment coating layer. This is a magnetic thermosensitive recording paper that is characterized by:
