（ａ） 発明の目的
本発明は昇華性色素を使用する感熱転写記録用の受像体
に関する。DETAILED DESCRIPTION OF THE INVENTION (a) Object of the Invention The present invention relates to an image receptor for thermal transfer recording using sublimable dyes.
（産業上の利用分野）
本発明の昇華性色素使用の感熱転写記録用の受像体は、
近年急速に普及しつつあるファクシミリ、プリンタ、複
写機等のＯＡ端末機におけるカラー記録やテレビ画像の
カラー記録用等に有利に使用できる。(Industrial Application Field) The image receptor for thermal transfer recording using the sublimable dye of the present invention is:
It can be advantageously used for color recording in office automation terminals such as facsimiles, printers, and copying machines, which have become rapidly popular in recent years, and for color recording of television images.

式に較べて有利である。(Prior Art) Various methods such as electrophotography, inkjet, and thermal transfer recording are being considered for color recording such as color recording in the above-mentioned OA terminals and color recording of television images.
The thermal transfer recording method is advantageous over other methods in terms of maintainability of the device, ease of operation, and low cost of the device and consumables.

背面を感熱ヘッドで加熱して、カラーシート中の色素を
受像体に転写させることによ抄記録が行なわれる。In the thermal transfer recording method described above, an image receptor is placed on the ink-coated surface of a color sheet, which is completely coated with ink containing a dye binder, etc., on a sheet-like base material, and the back side of the color sheet is heated with a thermal head. Then, paper recording is performed by transferring the dye in the color sheet to the image receptor.

、カラー記録用に特に有利である。Such thermal transfer recording methods include a melt transfer recording method that uses a color sheet coated with heat-melting ink, and a sublimation transfer recording method that uses a color sheet coated with an ink containing a sublimable dye. This method is particularly advantageous for color recording because the sublimation transfer t' of the dye can be easily controlled by adjusting the energy applied to the thermal head, making it easy to express one gradation.

録後の両者のはく離が困難となる問題点があった。In the sublimation transfer recording method, since it is necessary to dye the image receptor with the dye sublimated from the color sheet, the surface of the image receptor is mainly made of thermoplastic resin that has a high affinity with the dye used. However, since the temperature of the thermal head is generally 200°C or higher, the ink binder of the color sheet and the thermoplastic resin of the image receiving layer are This causes a problem in that the color sheet and the image receptor are fused together, making it difficult to separate them after recording.
また、得られた記録は、長期間にわたってその記録の色
調が退色したり、或いは変色したりしないこと、記録の
画像がぼけてしまわないことなどの記録の長期安定性が
求められていた。In addition, the obtained records are required to have long-term stability, such that the color tone of the records does not fade or discolor over a long period of time, and the recorded images do not become blurred.

り、色濃度の低下や色むらを生じやすく、また転写時に
顔料の表面に付着した色素が、後で他の紙等を汚染する
欠点があった。Conventionally, methods for preventing such fusion between the color sheet and the image receptor include a method of improving heat resistance by using a cross-linked resin in the image-receiving layer (JP-A-58-215398, JP-A-58-212994). (Japanese Unexamined Patent Publication No. 107885/1984), or a method of roughening the surface of the image-receiving layer by adding a pigment to the resin of the image-receiving layer. but,
The former method has the drawback that the resin of the image-receiving layer is cured by crosslinking, resulting in poor dyeing during transfer and low color density. In addition, in the latter method, due to the roughening of the surface, the adhesion between the color sheet and the image receptor during transfer is insufficient, which tends to cause a decrease in color density and color unevenness. However, it had the disadvantage of contaminating other papers etc. afterwards.

記録の安定性の面で問題があった。Furthermore, as an attempt to prevent melting between the color sheet and the image receptor, there is a method of applying silicone grease on the image receiving layer (Japanese Patent Laid-open No. 165688/1988), or a method of applying silicone grease to the image receiving layer, or a method of applying silicone grease to the image receiving layer. Method of containing reaction cured product with modified silicone (Japanese Patent Application Laid-Open No. 60-348
No. 98) was proposed. However, methods using these silicone-based compounds have the drawback that the transferred dyes in the former are eluted into the grease and seep into the image, and the latter are likely to react with dyes such as amino groups and epoxy groups on the silicone. Due to the reactive nature of the stone, the transferred pigment would decompose, resulting in problems with the stability of the record, such as an extremely short record life.
