低下する。Taking advantage of this characteristic, in the label industry, a bar code, a product name, a price, and the like are printed on a label by using this method, and a label of a small lot type is created. The bar code on the label is read using, for example, a light pen. At this time, the shape of the bar code made of the transfer ink is often broken due to abrasion at the tip of the light pen, so that accurate information cannot be read. The same thing is likely to occur when a product to which a barcode-printed label is attached touches a surrounding item during handling. Currently, the wax-based thermal transfer ink, which constitutes the transfer layer of the thermal transfer recording material used for thermal transfer recording, is soft in itself and has abrasion resistance, and is printed on resin-coated paper such as mirror-coated paper. In this case, the abrasion resistance is particularly reduced.

がある。The adhesive layer (5) is mainly composed of a polyamide resin having a softening point of 90 to 180 ° C., which serves to improve the adhesion to the image receiving paper. Further, since this layer does not contain a coloring material, it also has a role of preventing background contamination at the time of printing. This polyamide resin is
It is necessary to change physical properties depending on the thicknesses of the release layer and the colored layer. When the thickness of the release layer and the coloring layer is large, a low softening point within the range of the softening point described above, and a material having a low melt viscosity,
On the other hand, when it is thin, a material having a high softening point and a high melt viscosity is preferred. If the softening point of the resin is 90 ° C. or lower, the storage stability of the recording medium itself deteriorates, and if it is 180 ° C. or higher, a situation in which the resin is not transferred at the time of transfer occurs.
