本発明は熱昇華性染料の加熱による昇華現象を利用して
画像の記録を行う熱転写記録装置に使用される色彩転写
シート及び該シートによる熱転写記録方法に関するもの
である。Detailed Description of the Invention [Industrial Field of Application] The present invention relates to a color transfer sheet used in a thermal transfer recording device that records an image by utilizing the sublimation phenomenon caused by heating of a heat-sublimable dye, and a color transfer sheet using the sheet. This relates to recording methods.
熱転写記録装置による記録方法としては、従来より主と
して次の二種類に大別される。Recording methods using thermal transfer recording apparatuses have conventionally been broadly classified into the following two types.
すなわち、その一つは、熱溶融性ワンクスに顔料を分散
混合した熱溶融性顔料より成る色彩層を薄い合成樹脂フ
ィルムから成るシート基材上に設けることにより形成し

、前記色彩層をサーマルヘッ゛ド等の加熱手段により加
熱して、これにより溶融した色彩層を記録媒体に転写す
ることで、記録媒体上に図形や文字等の画像を得る所謂
熱溶融式の方法である。Specifically, one method is to record a color transfer sheet on a platen, which is formed by providing a color layer made of a heat-melt pigment dispersed in heat-melt Wanx on a sheet base material made of a thin synthetic resin film. The color layer is superimposed on a medium, heated by a heating means such as a thermal head, and the molten color layer is transferred to the recording medium, thereby producing images such as figures and characters on the recording medium. This is a melting method.
また、別の一つは熱昇華性材料に染料を分散混合した熱
昇華性染料より成る色彩層をシート基村上に設けること
により形成した色彩転写シートをプラテン上で記録媒体
に重ね合わせ、サーマルヘッド等の加熱手段により前記
色彩層を加熱昇華させることにより記録媒体に転写する
ことで、記録媒体上に図形や文字等の画像を得る所謂熱
昇華式の方法である。Another method is to form a color transfer sheet by providing a color layer made of a heat-sublimable dye dispersed in a heat-sublimable material on the sheet base layer, which is then superimposed on a recording medium on a platen. This is a so-called thermal sublimation method in which images such as figures and characters are obtained on the recording medium by heating and sublimating the color layer using a heating means such as the above and transferring it to the recording medium.
このうち、前者の熱溶融式の記録方法は、記録媒体とし
て普通紙等の紙類を使用できることから、各種情報端末
における出力用の記録装置等に広く利用されている。Among these, the former thermal melting type recording method is widely used in output recording devices for various information terminals because it can use paper such as plain paper as a recording medium.
それに対して後者の熱昇華式の記録方法は、前者程普及
していないものの、多色で連続階調の画像が得られると
いう特長を有するので、今後需要の増加が見込まれるが
、そのためには解決すべき以下の問題がある。On the other hand, the latter thermal dye sublimation recording method is not as popular as the former, but it has the feature of producing multicolor and continuous tone images, so demand is expected to increase in the future. There are the following problems to be solved.
すなわち、熱昇華性式の記録方法の場合、普通紙等の紙
類はその表面が色彩転写シートから移行してくる色彩層
の染料を十分受容することができないので、記録媒体と
して紙類を用いると高濃度の発色画像が得られず、定着
性も極めて悪いという難点がある。In other words, in the case of a heat sublimation type recording method, the surface of paper such as plain paper cannot sufficiently absorb the dye of the color layer transferred from the color transfer sheet, so paper is used as the recording medium. However, there are disadvantages in that high-density colored images cannot be obtained and the fixing properties are also extremely poor.
従って、前記熱昇華式の記録方法の場合、記録媒体とし

も極めて悪く、取り扱い難いという問題があった。Therefore, in the case of the thermal sublimation recording method, a special resin film with a flat surface such as polyester resin is generally used as the recording medium, and therefore paper such as plain paper is used as the recording medium. There have been problems in that they cannot satisfy the needs of users, have extremely poor cost performance, and are difficult to handle.
本発明はこれらの問題を解決するためになされたもので
、熱昇華性染料による高濃度の発色画像を普通紙等の紙

目的とするものである。The present invention was made to solve these problems, and includes a color transfer sheet that can record high-density colored images using heat-sublimable dyes on paper such as plain paper, and has good fixing properties, and a color transfer sheet based on the sheet. The purpose is to realize a thermal transfer recording method.

そしてこの記録方法において、前記受容層の記録媒体へ
の転写は、画像を記録すべき領域全域にわたって行うか
、または画像を記録すべき部分のみに行うものとする。In this recording method, the receiving layer is transferred to the recording medium over the entire area where the image is to be recorded, or only in the area where the image is to be recorded.
上述した手段によると、熱昇華転写を行う前段階におい

る。According to the above-mentioned means, the receiving layer of the color transfer sheet is transferred to the recording medium by heating means in the step before thermal sublimation transfer, and a smooth receiving layer made of synthetic resin is formed on the surface of the recording medium. This ensures the density and fixation of the color layer during subsequent heat sublimation transfer, and therefore even if paper such as plain paper is used as the recording medium,
A colored image with high density can be obtained and its fixability is also good.

場合によっては画像が見に（くなることが予想される。The above description has been based on one embodiment of the thermal transfer recording method, but according to the above method, the receptor layer is formed over the entire surface of the recording medium 10 for one page by transferring the receptor layer 2, so the image recording surface The gloss is added by the synthetic resin receptor layer, so if there are many images with text,
In some cases, it is expected that the images will be difficult to view.
このような不都合を解消するための記録方法を次に説明

容層を形成する。That is, in this method, the receiving layer 2 of the color transfer sheet 6 is first positioned at the position where the color gradation image is to be recorded on the recording medium 10, as in the case described above, and then the heating elements of the heating means 11 are activated based on the recording data. The receiving layer 2 is heated by simultaneously or selectively generating heat, thereby transferring the melted receiving layer 2 to the surface of the recording medium 10 to form a receiving layer.
つまり、ここでは後で色彩階調画像を形成する部分のみ
に受容層２を転写して受容層を形成する。That is, here, the receptor layer 2 is transferred only to the portion where the color gradation image will be formed later to form the receptor layer.
そして、以後前記の場合と同様に色彩層３ａ〜３ｃを転

図形等による多色画像を得る。Thereafter, the color layers 3a to 3c are transferred in the same manner as in the above case, and the operation of running the recording medium 10 for one page is sequentially repeated, thereby forming a multicolor image of characters, figures, etc. on the recording medium 10. get.
ところで、上述した記録方法において主として文字部分
となるブラックの画像は３色の色彩層３８〜３ｃすなわ
ちイエロー、シアン、マゼンタを重ねることで得られる
が、より鮮明なブラックの画像を得るには、単色のブラ
ックを用いるのが望ましい。By the way, in the above-described recording method, a black image, which is mainly a character part, is obtained by overlapping three color layers 38 to 3c, that is, yellow, cyan, and magenta, but in order to obtain a clearer black image, a single color It is desirable to use black.
そこで、記録する画像のうち、ブラックの画像の領域が

After recording a multicolor image by transferring a to 3c,
The heat-melting color M5 is selectively heat-melted by the heating means 11 based on the recorded data and transferred to the portion of the recording medium 10 where the receptor layer is not formed, that is, the area that will mainly be the character portion.
この記録方法ではブラックの画像を熱溶融性の色彩層５

射にて見やすいものとなる。In this recording method, a black image is recorded in a heat-fusible color layer 5.
In particular, the character portions are easier to see due to the reflection of natural light.
尚、上述した実施例では加熱手段１１としてサーマルヘ

て記録媒体として普通紙等の紙類を用いても、高濃度の
発色画像が得られ、また定着性もよいものとなる。As explained above, in the present invention, a color transfer sheet is formed by providing a heat-melting receiving layer containing a synthetic resin and a plurality of color layers made of a heat-sublimable dye on a sheet base layer, and heating means is applied to the color transfer sheet. The receptor layer of the color transfer sheet is transferred to a recording medium made of paper, and a smooth receptor layer made of synthetic resin is formed on the surface of this recording medium, so that the density and fixation of the color layer during subsequent thermal sublimation transfer is improved. Therefore, even if paper such as plain paper is used as a recording medium, a high-density colored image can be obtained and the fixability is also good.
そのため、熱昇華式の記録方法においても記録媒体には
普通紙等の紙類を用いるものというユーザのニーズを満
足させることができ、かつコストパフォーマンスもよく
なるという効果が得られる。Therefore, even in the thermal sublimation type recording method, it is possible to satisfy the user's needs for using paper such as plain paper as the recording medium, and the cost performance is also improved.
