However, in a conventional sheet-like thermal transfer recording material using a removable adhesive material, there is a problem in that the conventional heat-transfer recording material has a thickness of 20.
When a re-peelable adhesive layer is provided on the ink surface or the outer peripheral margin of the ink surface of a thin thermal transfer ink sheet having a thickness of μ or less, or wrinkles are generated when the ink sheet with the adhesive is attached to printing paper. However, it has a bad influence on printing and is difficult to put to practical use. In addition, if the thermal transfer ink sheet is pre-integrated with the printing paper with an adhesive or glue material, it is easy to use, but it is possible to select a specific printing paper according to the application and print with the desired ink color. Did not.
Further, when a plurality of ink colors are used in combination for small printing paper such as New Year's postcards, it has not been possible to select a printing color by replacing an ink sheet of a different color according to the application in a conventional thermal transfer recording material. Therefore, an object of the present invention is to provide a thermal transfer recording material that can freely select a combination of printing paper and ink color according to the use in multicolor printing of a small printed matter, and can further reduce the printing cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the thermal transfer recording material according to the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a thermal transfer recording material according to the present embodiment, FIG. 2 is a cross-sectional view of the thermal transfer recording material of FIG. 1 with the center omitted, and FIGS. 3 and 4 are plan views of the thermal transfer recording material of another embodiment. .

As shown in FIG. 1, a thermal transfer recording material according to the present invention includes a backing paper 1, a small printing paper 2 disposed at a predetermined position on the backing paper 1, and an ink layer surface 3A on the paper surface 2A of the printing paper 2. A thermal transfer ink sheet 3 which is superimposed as a heat transfer ink sheet 3, and a sheet-shaped cover 4 having an opening 7 at a position facing the outer surface 3B of the thermal transfer ink sheet 3 and having an opening area where a printer can print, and The sheet-like cover 4
Has a removable adhesive surface 4A on one side, and the adhesive surface 4A
The ink sheet 3 is removably attached to the outer peripheral surface 3B of the ink sheet 3 and the printing paper surface 2A and the mount surface 1A outside the peripheral surface 3B.

This embodiment will be further described.
Are relatively stiff sheets, such as papers and plastic sheets. The thickness of the mount 1 is preferably 50 to 1000 μ, and the size of the mount 1 is
A size that can be set in a printer and that is about A5 to A3 can be used. Three small printing papers 2 are arranged on the backing paper 1, and are arranged at positions facing the openings 7 of the sheet-like cover described later. The printing paper 2 has a surface 2A on which at least one surface can be printed.
Alternatively, the surface may be processed so that the ink is sufficiently transferred and fixed by the printer. Specifically, ordinary high-quality paper, other transfer paper, and in some cases, a plastic sheet may be used. Also, printing paper 2
The size of the ink sheet 3 to fix it
Desirably smaller. In the embodiment shown in FIGS. 1 and 2, the horizontal length of the printing paper is longer than the ink sheet 3. For this reason, a part 6 of the printing paper surface 2A protruding from the ink sheet 3 is fixed by the sheet-like cover described later, and the displacement of the printing paper 2 is prevented.

As shown in FIG. 1, the size of the thermal transfer ink sheet 3 is such that the length A (or length) and the width B (or width) are shorter than the length and width of the mount 2. Therefore, 3
The ink sheet 3 is sandwiched between two small printing papers 2, 2, 2.
Is superimposed on the mount 1, the outer peripheral surface 1 </ b> A of the mount 1 comes out of the outer periphery 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 having a size of about 15 μ or less, and a specific film carrier is a polyethylene terephthalate film or the like.

The sheet-like cover 4 has an adhesive surface 4A,
The edge outer surface 3B of the ink sheet 3 and the printing paper surface 2
A is attached over part 6 of A and the peripheral surface 1A of the backing paper 1. That is, as shown in FIG.
Two openings 7, 7, 7 are formed to form a frame. The sheet-shaped cover 4 covers the peripheral outer surface 3B of the ink sheet 3 and partially covers the peripheral surface 6 of the printing paper 2 so that the ink sheet 3 is exposed from the opening 7. In addition, since the ink sheet 3 is overlapped on the printing paper 2 and the backing paper 1 with the ink layer surface as the inner surface, the adhesive surface 4A of the sheet-like cover 4 adheres to the base material surface 3B side of the ink sheet 3. Therefore, the sheet-like cover 4 is a frame, and the adhesive surface 4A
Is attached to the substrate surface of the ink sheet 3,
Wrinkles and the like hardly occur on the thermal transfer ink sheet 3. The sheet-like cover 4 preferably has a thickness of 50 to 1000 μ and has a certain shape-retaining property. As a specific material for the sheet-like cover 4, besides stiff paper, a film or sheet of polystyrene, polypropylene, polyester, or the like can be used. In FIG. 1, paper is used. In particular, paper is low in chargeability and easy to use.

The adhesive surface 4A of the sheet cover 4 is a removable adhesive surface. For this reason, the sheet cover 4 can be peeled off from the thermal transfer ink sheet 3 and the printing paper 2 and re-attached. The adhesive force between the adhesive surface 4A and the printing paper surface 2A or the thermal transfer ink sheet surface 3B is 1
80 ° peel adhesion of 300 gf / 10 mm or less, especially 2
50 gf / 10 mm or less (measurement method: JIS Z 023)
7) is desirable. As shown in FIG. 1, the adhesive surface 4A of the sheet-like cover 4 is formed as a surface of an adhesive material 8 which is present in a dot shape or a block shape. Such an adhesive material 8
Is applied without repetition, it is possible to easily impart removability to the adhesive surface 4A. The discontinuous presence means that the adhesive 8 is present to the extent that air bubbles escape between the objects to be bonded during re-bonding. When the adhesive material 8 is discontinuously provided as described above, the bonding target can be easily brought into close contact during re-bonding. Therefore, the ink sheet 3 and the sheet-shaped cover 4 can be bonded together without causing wrinkles or the like. The amount of the adhesive material 8 applied is such that the sheet area is 5 m.
coated surface per m ² is 3 to 80%, particularly preferably 1
0 to 60%.

As the pressure-sensitive adhesive 8, a normal pressure-sensitive adhesive such as acrylic, urethane, rubber, eva, or olefin can be used in addition to a natural pressure-sensitive adhesive. The rubber-based pressure-sensitive adhesive is mainly composed of an elastomer, a tackifier resin, a softener, and the like. By combining these, physical properties can be balanced. The adhesive material 8 is preferably an acrylic (butyl acrylate) or urethane-based material used as a general synthetic adhesive material, and the above-described rubber-based adhesive material can be used by combining the main components. For example, elastomers include natural rubber (NR), isoprene rubber (IR), styrene-butadiene rubber (SBR), styrene-butadiene block copolymer (SBS), styrene-isoprene block copolymer (SIS), styrene-ethylene Butylene / styrene block copolymer (SEBS), butyl rubber, polyisobutylene, silicone rubber, polyvinyl isobutyl ether, chloroprene rubber, nitrile rubber, and graft rubber can be used.

[0013] As the tackifier resin, rosin, ester gum, Ester Gum H, polyterpene resins, C ₅ petroleum resins, C ₉ petroleum resins, DCPD petroleum resins, styrene resins, alkyl phenol resins, terpene phenol resins, and their hydrogenated products and the like can be used, preferably, polyterpene resins hydrogenated products, hydrogenation products of C ₅ petroleum resins, and the hydrogenated products C ₉ petroleum resin can be used. As the softener, various plasticizers, polybutene, liquid tackifier resin, polyisobutylene low polymer, polyvinyl isobutyl ether low polymer, lanolin, bulk polymerized rubber, process oil, naphthenic oil, paraffin oil, vulcanized oil Etc. can be used. Further, the total thickness when the backing sheet 1, the printing paper 2, the thermal transfer ink sheet 3, and the sheet cover 4 are stacked is preferably 3 mm or less, particularly preferably 2 mm or less. With such a thickness, printing can be performed without imposing a load on the printer.

As described above, according to the thermal transfer recording material having such a configuration, the outer peripheral surface 3B of the thermal transfer ink sheet 3 is covered with the sheet-like cover 4 having shape retention, and is fixed together with the printing paper 2 by the adhesive surface 4A. Then, heating printing is performed from the surface of the thermal transfer ink sheet 3 in the opening 7 of the sheet-like cover 4. For this reason, the thermal transfer ink sheet 3 moves smoothly in the printer without shifting from the printing paper 2 and without wrinkles,
Does not cause printing failure. Further, there is no adhesive portion between the thermal transfer ink sheet 3 and the printing paper 2, and both are provided removably via the sheet-like cover 4. In addition, since the adhesive surface 4A of the sheet-shaped cover 4 is removably adhered to the substrate surface 3B of the thermal transfer ink sheet 3, an ink sheet of a color according to the use can be selected and used. The sheet-like cover 4 can be used again, and printing costs are lower than when an ink ribbon in a cassette is used. Further, even when the printing paper 2 is small and cannot be directly set in the printer, no problem occurs as long as the size of the backing sheet 1 and the sheet-like cover 4 is a predetermined fixed paper size.

In the above-described embodiment, the adhesive material 8 is provided on the adhesive surface 4A of the sheet-shaped cover 4 in a dot-like manner so as to be a releasable surface. However, the present invention is not limited to this. For example, a removable adhesive layer having adhesiveness to the smooth surface of the mount 1 may be used. The removable adhesive layer is a layer having a suction function in which countless fine suction cups are formed on the surface, and examples of the material thereof include a foam mainly composed of a flexible acrylic resin. Such an adhesion layer is foamed by stirring an aqueous emulsion of an acrylic resin, applied to the sheet-like cover surface, and subjected to mirror finishing or calendering during the drying process of the applied surface. A fine suction cup is formed on the application surface. The sucker diameter of the removable adhesive layer having such a sucker function is 2
0 to 400μ, particularly preferably 50 to 200μ, its depth is 10 to 200μ, particularly preferably 20 to 150μ, and its density is 500 to 1000 pcs / c
m ² , particularly preferably 1,000 to 7000 / cm ² . As a specific example of such a removable adhesive layer, HISTAR-FK (trade name, manufactured by Hirose Paper Co., Ltd.) is suitable.
