本発明は感熱転写記録紙の改良された製造方法
に関し、特に感熱転写層形成用インキの塗工時に
特別の加熱手段を用いない感熱転写記録紙の製造
方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved method for manufacturing thermal transfer recording paper, and particularly to a method for manufacturing thermal transfer recording paper that does not use special heating means during application of ink for forming a thermal transfer layer.
近年、コンピユーターやフアクシミリ等の各種
出力端末の出力方式として、低騒音、メンテナン
スフリー性、装置の簡便性、小型軽量化が可能で
ある事等の理由で感熱転写型記録法の開発が進め
られている。 In recent years, thermal transfer recording methods have been developed as an output method for various output terminals such as computers and facsimile machines due to their low noise, maintenance-free nature, simplicity of equipment, and ability to be made smaller and lighter. There is.

ある。 Thermal transfer recording paper has a thermally conductive substrate with
It is coated with a binder made of wax or other low-melting point substance that softens or melts when heated, mixed with a coloring agent, etc., and the recording medium and the transfer layer of the transfer paper are combined and patterned with a heat-sensitive head. The image is printed on the recording medium by printing on the recording medium.
これらの感熱転写記録紙の製造法としては、従

用されている。 As methods for producing these thermal transfer recording papers, conventionally used are hot melt coating method and hot liquid coating method in which the above-mentioned ink binder is dissolved in a solvent by heating to usually 40° C. or higher and applied.
ホツトメルトコーテイング法は、バインダー自
体が常温では固体であるので、バインダーの融点

従来使用しているワツクスは40℃以下では溶剤中
に溶解しないので、40℃以下の常温ではインキの
塗布が困難で、何等かの加熱手段を用いなければ
良好な塗布はできない。 On the other hand, the hottrusker coating method, also called the solvent coating method, is a method in which the binder is dissolved in a solvent under heating and applied.
In this method, a binder and a solvent are mixed, heated to a temperature lower than the melting point of the binder, and the binder is dissolved in the solvent before being applied. Since it does not dissolve in solvents, it is difficult to apply ink at room temperatures below 40°C, and good application cannot be achieved unless some heating means is used.

とにより、塗布適性を保持する必要がる。 Of course, it is possible to apply the binder by simply finely dispersing it in a solvent (so-called emulsion), but this will cause unevenness such as so-called "swimming" on the coated surface, resulting in uneven printing during transfer. Good transfer print quality cannot be obtained. That is,
This is because there is no dissolved binder component, so a uniform film cannot be formed on the substrate surface. Therefore, it is necessary to maintain coating suitability by dissolving the binder in a solvent using heating means during coating.

に至つたものである。 As a result of examining the suitability of various compounds as binders as inks for heat-sensitive transfer layers, the present inventor found that certain compounds
The present invention was achieved by discovering that it is at least partially soluble in general low-boiling point organic solvents at a temperature of 40°C and is suitable as a binder for thermal transfer forming inks.

For example, polyester, polypropylene,
Polystyrene, polycarbonate, polyimide and other plastic films, glassine paper,

Furthermore, even if heating is used to adjust the viscosity of the ink or to keep the coating machine warm, it is possible to sufficiently adjust the viscosity and keep the coating machine warm at a temperature of 40°C or less.

度の優れたものである。 Furthermore, in the heat-sensitive transfer layer formed by the method of the present invention, at least a portion of the wax is dissolved in the solvent even when the ink used is at room temperature.
There is no phenomenon such as so-called "swimming" in the coating layer, and the heat-sensitive transfer layer has a smooth surface with no uneven coating.
Therefore, the printed characters transferred by this method are also clear and have excellent resolution.

本発明では塗布時に加熱を要しないのでこの様な
問題も解決されている。 On the other hand, the conventional hot tracker coating method and hot melt coating method require a heating means and its temperature control, and if temperature control is inadequate, coating may become difficult, and uneven coating or thickness problems may occur. There is a problem that uniformity occurs, but
In the present invention, this problem is solved because heating is not required during coating.

イプ状の感熱転写層等の形成も容易である。 Furthermore, with conventional coating methods that require heating during coating, it is difficult to form a multicolor heat-sensitive transfer layer by overprinting, but according to the method of the present invention, the heat-sensitive transfer layer once formed can be softened or eroded. Since there are no layers, overprinting is possible, and it is easy to form multicolor patterns, striped heat-sensitive transfer layers, etc.
更に常温で行う従来のソルベントコーテイング

決されている。 Furthermore, in the conventional solvent coating method, which is carried out at room temperature, the binder is not dissolved in the solvent, so so-called "swimming" occurs, resulting in an uneven heat-sensitive transfer layer, but the present invention solves this problem. There is.

Transfer-type multicolor thermal transfer recording paper can also be easily provided, and as in the conventional hot melt coating method, each color printing or coating unit is heated, and once the ink has been transferred, it is difficult to adhere to the plate. No other inconvenience will occur.
