FIELD OF THE INVENTION The present invention relates to a thermal transfer recording medium,
More particularly, it relates to a thermal transfer recording medium on which an image printed by thermal transfer is formed as matte, and relates to a thermal transfer ribbon used in computers, word processors, bar code printers, facsimiles and the like.

2. Description of the Related Art Generally, a printing mechanism using a thermal transfer recording system uses a thermal transfer recording medium in which a heat-meltable ink layer is provided on a base material (heat-resistant support) directly or via a peeling layer. In order to obtain a printed image by heating the base material from the base material side with a thermal head etc. to melt the heat-meltable ink layer in the state where it is overlaid with the transferred material (image-receiving paper etc.) and transferring this melted ink to the image-receiving paper To do.

By the way, in the past, when an ordinary thermal transfer recording medium is used, the printed image often has gloss and smear property (a property that the printed image is rubbed and falls off). This tendency makes the printed image difficult to see and is extremely disadvantageous in reading the printed image, especially when the printed image is a bar code.

In order to eliminate these disadvantages, (1) a matting agent is mixed in the hot-melt ink (JP-A-56-16).
4891), (2) providing a mat layer on a substrate (Japanese Patent Laid-Open No. 60-101083), (3) a releasing layer comprising a matting agent, a releasing agent and a thermosetting resin in pattern transfer. To make the image matt (Japanese Patent Publication No. 51-1)
4056), (4) The image is delustered by roughening the surface of the support (JP-A-56-10599).
No. 4) is proposed.

However, in the above-mentioned means (1), a white inorganic pigment is usually used as a matting agent, and if the amount used is small, the matting effect is difficult to obtain, and conversely, the amount used. If the amount is large, the print quality and the transfer density are deteriorated and the smear resistance is deteriorated. Further, in the above (2), the components forming the matte layer are considerably limited, and moreover, it cannot be said that the smear resistance is good. In addition to these, if unevenness is provided on the surface of the base material, it is difficult to control the degree of unevenness. With the means (3), the construction itself of the thermal transfer recording medium is quite troublesome. In the means of (4) above, it is essential that the ink layer carrying surface is roughened, and as in the case of (2) above, strict conditions can be satisfied for the production. However, it is also known to provide a mat layer between the heat-fusible ink layer and the peeling layer, but using such means complicates the layer structure, leading to increased costs and reduced productivity. There is.

Further, (5) a layer containing a colorant and a higher fatty acid metal salt and / or a higher fatty acid amide is provided between the substrate and the heat-fusible ink layer to cause cohesive failure during thermal transfer. A proposal has also been made to obtain a matte printed image (Japanese Patent Laid-Open No. 1-290493). However, when the thermal transfer recording medium of (5) is subjected to thermal transfer recording without any conditions, the above (1) still remains.
In many cases, the drawbacks pointed out in (2) occur.

The present invention will be described in more detail below with reference to the accompanying drawings. 1 to 3 show three typical examples of the thermal transfer recording medium according to the present invention. In FIG. 4, the matte layer 2 of the thermal transfer recording medium is not transferred to the receiving paper 7,
A state in which the thermal transferable ink layer 3 (or the intermediate layer 6) is peeled off from the interface with the non-transferable matte layer 2 and transferred, and a matte image is obtained on the receiving paper 7 due to the unevenness of the surface It represents. In the figure, 8 is a thermal head.

FIG. 1 shows the most basic thermal transfer recording medium of the present invention, in which a mat layer (non-thermal transfer mat layer) 2 is formed on a support 1, and an ink layer (thermal transfer ink) is further formed thereon. Layer 3 is formed. The ink layer 3 is

The thermal transfer recording medium of the present invention is shown in FIGS.
As shown in FIG.
a, 3b) and (3a, 3b, 3c), etc.] to have a peeling property to improve the thermal sensitivity, or the ink layer 3 and the matte layer 2
It is also considered that an intermediate layer 6 may be provided between the layer and to improve the releasability (FIG. 2), and that an overcoat layer 5 may be provided to improve the thermal sensitivity and prevent background stains (FIG. 3). Good. Furthermore, it is preferable that the ink layer 3 contains unvulcanized rubber, whereby the abrasion resistance and scratch resistance of the image are further improved.

Examples of the support 1 include relatively heat-resistant plastic films such as polyester, polycarbonate, triacetyl cellulose, nylon, and polyimide, as well as glassine paper, condenser paper, metal foil, and the like. Is about 2 to 15 μm, preferably 3 to

On the surface of the support 1 in contact with the thermal head (the surface opposite to the side where the ink layer 3 is present), silicone rubber, silicon-modified urethane resin, or silicon-modified acrylic resin is used, if necessary. By providing a back layer (heat-resistant protective layer) 4 made of, for example, the coefficient of static and dynamic friction of the support 1 can be lowered, and the transportability can be improved, or a support material that has not been used conventionally can be used.

More preferably, it is 10 or less (at 5 ° C.) (at 50 ° C.). By taking such a value, the abrasion resistance of the image becomes remarkably good. If the penetration is more than 3, the abrasion resistance and scratch resistance will be poor, and if the elongation exceeds the above value, the image will not be sharp.

As the colorant in the ink layer 3, carbon black or a conventionally known inorganic or organic dye or pigment is used. In addition, a binder, a dispersant, a pigment and the like can be added if necessary.

As the binder, unvulcanized rubber such as polybutadiene and nitrile rubber is preferable, and other polyethylene,

As the dye / pigment, the materials described in the matte layer are used.

Known dispersants can be used, and examples thereof include polyacrylic acid, styrene-maleic acid copolymers, ethylene glycol, sodium hexametaphosphate, and various surfactants.

The thickness of the heat transferable ink layer 3 is 0.5 to 6 μm.
m is preferably 1 to 5 μm.

In the thermal transfer recording medium of the present invention, as mentioned above, the intermediate layer 6 is provided between the mat layer 2 and the ink layer 3 so as to have a peeling property and to improve the thermal sensitivity. It is effective in improving the abrasion resistance and scratch resistance of the image (Fig. 2). It is desirable that the intermediate layer 4 is formed by using unblended rubber, preferably butadiene rubber as a main component. Middle layer 6

It is preferable to dry at a temperature of 86 ° C.) or lower to form particles.

In the thermal transfer recording medium of the present invention, the thermal transferable ink layer 3 may be a single layer or a multilayered layer 3.
In the case of a, 3b, 3c ..., It is desirable that the wax component accounts for 60% by weight or more of all the ink layer components. The thickness of the thermal transferable ink layer 3 is 0.5 to 6 μm in total, preferably 1 to 5 μm, as in the above-described example. In addition, as the constitution of the multi-layer ink layer, a layer mainly containing wax as the first ink layer 3a and the second ink layer 3
