Abstract

PURPOSE:The titled sheet low in cost and capable of multi-color recording and intermediate tone recording with only a single heat-sensitive recording layer, wherein a heat-sensitive recording layer comprised of particulates of plural kinds of heat-fusible inks having different melting points and a high polymer functioning as an adhesive is applied onto a base. CONSTITUTION:The heat-sensitive recording layer 20 comprised of the particulates of plural kinds of heat-fusible inks (each of which is preferably comprised of a low melting point substance such as a wax, a softener such as oleic acid and a coloring material such as a pigment or a dye) 30, 40 diferring in color tone in accordance with melting point and a high polymer (e.g., polyvinyl butyral, having a film-forming property) 50 functioning as an adhesive is applied onto the base 10 to obtain the objective thermal transfer sheet. The melting point of the high polymer 50 is preferably higher than those of the inks 30, 40. When recording, electric power supplied to a thermal head is controlled, and only the low melting point ink 30 is transferred onto a recording paper when a small quantity of electric power is supplied, while both of the inks 30, 40 are transferred when a large quantity of electric power is supplied.

Description

【発明の詳細な説明】 本発明は熱転写シート、特に中間調記録あるいは多色記
録を得ることができるようにした熱転写シートに関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thermal transfer sheet, and particularly to a thermal transfer sheet capable of producing halftone recording or multicolor recording.

熱転写記録方式は基材上に熱溶融性インク層を設けた熱

から普通紙をはく離して、普通紙上に記録を得る方式で
ある。Thermal transfer recording method uses a thermal transfer sheet with a heat-melting ink layer on the base material. Plain paper is brought into close contact with the ink layer surface of the thermal transfer sheet, and heat is selectively applied from the base material side using a thermal head, etc. In this method, the ink layer is melted and the ink is applied to plain paper, and then the plain paper is peeled off from the thermal transfer sheet to obtain a record on the plain paper.

このような熱転写記録方式では可視記録像が普通紙上に
形成されるので、保存性の良い記録が得られるという利
点があり、プリンタやファクシミリに多く採用されてい
るが、近年カラー記録や、中間調記録への要求が高まり
、これらへの対応がなされつつある。This type of thermal transfer recording method forms a visible recorded image on plain paper, so it has the advantage of producing records with good storage stability, and is often used in printers and facsimile machines, but in recent years color recording and halftone Demand for records is increasing and efforts are being made to meet these demands.

従来、熱転写記録方式によるカラー記録としては互に色
調の異なる複数の熱転写シートを使用する多色記録と１
枚の熱転写シートで２色の記録が可能な２色記録がある

トを用いて２色目の記録を行い、再度普通紙を元の位置
に戻す、これを順次各色毎に繰り返して多色記録を得る
。この方法では各色の記録位置合せのため普通紙の精密
な位置合せ機構が必要になる。Conventionally, color recording using the thermal transfer recording method includes multicolor recording using multiple thermal transfer sheets with different tones, and one
There is two-color recording that allows two-color recording with a single thermal transfer sheet, but each of them has the following drawbacks. A multicolor recording method using multiple thermal transfer sheets with different tones uses the first color thermal transfer sheet to record the first color on plain paper, then returns the plain paper to its original position and records the second color. A second color recording is performed using a thermal transfer sheet, the plain paper is returned to its original position, and this process is repeated for each color in order to obtain a multicolor recording. This method requires a precise positioning mechanism for plain paper in order to align the recording positions of each color.

またこれに使用される熱転写シートは中間調記録が不可
能なため、例えば３色の熱転写シートを用いても７色の
記録しか行えないという欠点もある。Furthermore, since the thermal transfer sheet used for this is incapable of halftone recording, there is also the drawback that, for example, even if a three-color thermal transfer sheet is used, only seven colors can be recorded.

ここで中間調記録、例えば３階調の記録が行えるならば
３枚の熱転写シートでも２７色の記録が可能となる。If half-tone recording, for example three-tone recording, is possible, then 27 colors can be recorded even with three thermal transfer sheets.

法で、３階調の記録が得られるが、これも同様にコスト
が高くなるという欠点を持っている。Next, a recording method using a thermal transfer sheet capable of two-color recording is as shown in Fig. 1, in which heat-melting ink layers having different melting points and tones, such as a low-melting point ink layer 1 and a high-melting point ink layer 2, are formed on a base material. Using sheets with a laminated structure, recording is performed by changing the amount of heat applied to the thermal transfer sheet, such as the electric power applied to the thermal head, to transfer only ink layer 1 or the heat-melting ink of ink layers 1 and 2 onto plain paper. . Therefore, this method does not require the above-mentioned positioning mechanism when only two-color recording is required, but since the heat-melting ink with different melting points is applied on the base material 3 in two parts, it is necessary to use the thermal transfer sheet. The disadvantage is that the cost is high.Furthermore, a recording method that uses a similar structure and is capable of halftone recording is that the ink layers 1 and 2 in FIG. A recording method using a thermal transfer sheet with a higher height can provide three-tone recording, but this also has the disadvantage of high cost.

An object of the present invention is to provide a thermal transfer sheet that uses a thermal transfer sheet having a structure in which only one thermal recording layer is provided on a base material, and is capable of two-color recording or halftone recording.

録、あるいは中間調記録ができる。Here, the heat-melting inks 30 and 40 are made of a low melting point substance such as wax, a softener and a coloring agent, and the low melting point substance used is polyethylene, paraffin wax, carnauba wax, etc., and the softener is olein. Acid, castor oil, etc. are used, and as the coloring agent, pigments and dyes used in ordinary printing inks are used. Further, as the polymer 50, polyvinyl butyral, epoxy resin, etc. can be used, but it is necessary to have film-forming properties in order to form a heat-sensitive recording layer. To perform recording using the thermal transfer sheet shown in FIG. 2, a plain paper (not shown) is brought into contact with the heat-sensitive recording layer 20 side, and a thermal head (not shown) is pressed against the thermal head from the base material 10 side. This is done by selectively generating heat from the heating element, but by controlling the power supplied to the thermal head, out of the heat-melting inks 30 and 40, only the low-melting point ink 30 is transferred onto the plain paper when low power is supplied. When high power is supplied, both heat-fusible inks 30 and 40 are transferred, allowing two-color recording or halftone recording.

In addition, if the melting point of the polymer is lower than or equal to that of the low melting point ink, the entire thermosensitive recording layer will be transferred onto plain paper with low power supply, so it is desirable that the melting point of the polymer is higher than the melting point of the thermofusible ink. .
