Abstract

PURPOSE:To attain to prevent sticking and to reduce the abrasion of a printing head, by providing a heat meltable ink layer to the single surface of a support and forming a heat resistant protective layer to the opposite surface there of by coating starch particles along with a binder solution. CONSTITUTION:A thermal transfer material 11 is formed by applying a heat meltable ink layer 3 to the single surface of a support 4 while further applying a heat protective layer 12, which is a discontinuous layer formed by coating starch particles along with a binder solution, to the back surface of said support 12. By this method, sticking is effectively prevented even if a coating amount is reduced and, in addtion, a printing head is hardly abraded.

Description

[Detailed description of the invention] Involved in thermal transfer material 1. .

I'm so excited! 〕〕　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　〕 Neawase ()3I Kushimiri, TJ Npi, J-Yuhata Miki,
This is a recording medium that is printed using a two-double 1" printing method.

This thermal transfer material is used in a compact manner as shown in FIG. 1. In FIG. 11 in: 1 layer (
The back side of the image receiving paper (2) superimposed on the soil of 3 mm was applied with a pressure of 11 times using the Blaan II-Ra (7).
A thermal pulse is applied to the printing head (5) from the back side of the paper (1) to selectively melt the 1-in-1 layer (3) into the paper (2). It was transferred to a printed image (
6) is formed.

This J, Una iJi 'lI/l Shasha, J3i-C, has a support body (4) in contact with the cylinder head (5) that is made of plastic (-), which is softened under heating and becomes a so-called plastic film. This causes a lie-1-ing phenomenon, which impedes the running of the transfer material, which in turn causes the transfer of the material to the head (
5) may cause damage.

However, for both plans 71.1 and 71.1, the solid content is c 3 s/l.
If you don't have a coating of 112 or higher, the effect will be weak, and it has the disadvantage that it is easy to wear out the resistance of 11.

When a person moves around, or when a natural pulse of 6 or more is applied, the above starch may diffuse and cause imprints, which may lead to inability to snore.

These molten d1 easily form scum and harden onto the surface of the support layer.

As the support C used in the present invention, polynisful film is often used, but polyimide 1b and long-lasting resin film 1b are used. When the heat-resistant protective layer of the present invention is applied, low softening 1:j, which could not be used conventionally, is achieved.

In the present invention (13), the starch is added to the binder solution and b.
It is coated on the support. Generally, it is applied onto a support by the 3-bar coating method, the Gura 1115 method, the Root Soh method, and the Smoothing Par 17j method. In a preferred embodiment of the present invention, the starch particles are preferably applied in discrete locations. Cf'J 4 as a discontinuous layer
The reason for this is that the print head comes into contact with the starch particles locally and creates a space with the cystic film, so there is less wear on the cylinder head.

The thermal printing material and photophotographic material of the present invention can be used in any shape such as a wide T-shaped or sheet-like shape such as a ribbon of a typewriter or a ribbon of a line printer.

To explain the embodiment of the present invention based on FIG. 2, the thermal transfer material (11) of the present invention has a support (4).
It is constructed by applying a heat-melting 11 ink layer (3) on one side of the support, and further coating a heat-resistant melting 1 protective layer ('+2), which is a discontinuous layer of starch particles, on the back side of the support. .
