FIGS. 2A to 2D are plan views of a thermal transfer recording material according to another embodiment.

As shown in FIG. 1, the thermal transfer recording material 1 according to the present invention has a printing paper 2, a thermal transfer ink sheet 3 having a smaller area than the printing paper 2, and a releasable adhesive surface 4A on one side. The ink sheet 3 is overlapped on the printing paper 2 with its ink layer surface 3A inside, and the edge paper 5 of the ink sheet 3 and the printing paper on the outside thereof are formed. The sheet-shaped cover 4 is removably attached to the surface 6 through the adhesive surface 4A.

[0008] To further explain the present embodiment, the printing paper 2 has at least one surface processed on a printable surface 2A or such a surface, and a surface on which ink is sufficiently transferred and fixed by a printer. It just needs to be. Specifically, ordinary high-quality paper, other transfer paper, and in some cases, a plastic sheet may be used. The size of the printing paper 2 is determined by the size and shape of the thermal transfer ink sheet 3 and the sheet-like cover 4 described later.

The size of the thermal transfer ink sheet 3 is smaller than the area of the printing paper 2, that is, as shown in FIG.
The length (or length) and the width B (or width) are shorter than the length and width of the printing paper 2. For this reason, when the ink sheet 3 is overlaid on the printing paper 2, the peripheral surface 6 of the printing paper 2 comes out of the peripheral edge of the ink sheet 3. The thermal transfer ink sheet 3 is desirably formed by coating the thermal transfer ink with a thickness of about 1 to 5 μ on glassine paper or a heat-resistant film carrier with a size of about 15 μ or less.
Examples include a polyethylene terephthalate film.

The sheet-like cover 4 has an adhesive surface 4A,
The ink sheet 3 is attached to the edge surface 5 and a part 6 of the printing paper 2. That is, as shown in FIG. 1, the sheet-like cover 4 has a frame shape with an opening at the center, and covers the peripheral surface 5 of the ink sheet 3 and the peripheral surface 6 of the printing paper 2 so that the central opening 7 is formed. The ink sheet 3 is exposed. In addition, since the ink sheet 3 is superimposed on the printing paper 2 with the ink layer surface inside, the adhesive surface 4A of the sheet-like cover 4 adheres to the base material surface 4B side of the ink sheet 3. Therefore, since the sheet-shaped cover 4 is a frame and the adhesive surface 4A is attached to the base surface of the ink sheet 3, wrinkles and the like are not easily generated on the thermal transfer ink sheet 3.
