本発明は、昇華型感熱転写記録に用いられる転写体に関
する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a transfer body used in sublimation type thermal transfer recording.

昇華型転写体の結着剤に求められる基本特性は、基材と
色材層の接着性を向上させること、又、熱転写記録時に
転写体の色材層と受像紙（記録紙）間の融着を防ぐこと
等である。Conventional technology The basic properties required of a binder for a sublimation transfer material are to improve the adhesion between the base material and the coloring material layer, and to improve the adhesion between the coloring material layer of the transfer material and the image receiving paper (recording paper) during thermal transfer recording. This is to prevent fusion between the two.
従来、結着剤として架橋性樹脂、ポリエステル系樹脂、
セルロース系樹脂等多数の樹脂が提案されている。（例

材との密着性はよいが高熱エネルギー域で熱融着を発生
しやすい等の問題点がある。Conventionally, crosslinked resins, polyester resins,
A large number of resins such as cellulose resins have been proposed. (For example, Japanese Patent Application Laid-Open No. 58-215397) 6 Problems to be Solved by the Invention Most of the binders that have been proposed so far have been made of highly heat-resistant resins or cross-linked resins to prevent fusion during thermal transfer recording. It is a polyester resin that has good adhesion to the base material. Resins with high heat resistance prevent thermal adhesion, but the recording density is particularly low in the low density region. Polyester resins have good adhesion to the base material, but have problems such as being prone to thermal fusion in a high thermal energy range.
本発明は受像紙との熱融着がなく特に低濃度域において
記録濃度が高く、又、基材と色材層間との密着性のよい
転写体を得ることを目的とする。An object of the present invention is to obtain a transfer member that does not undergo thermal fusion with the image-receiving paper, has a high recording density especially in the low density range, and has good adhesion between the base material and the color material layer.
問題点を解決するための手段
基材上に色素と結着剤とからなる色材層を有する転写体
において、前記結着剤が少なくとも１００℃以上の熱変
形温度を有する樹脂と共重合ポリエステル樹脂とから構
成されている転写体とする。Means for Solving the Problems In a transfer body having a color material layer consisting of a dye and a binder on a base material, the binder is a polyester resin copolymerized with a resin having a heat distortion temperature of at least 100° C. Let the transcription body be composed of the following.
作 用
１０ｏ′Ｃ以上の熱変形温度を有する樹脂は、高熱エネ
ルギ一部での熱融着を防止する。共重合ポリエステル樹
脂は、基材との密着性を保持し、又低濃度域（低エネル
ギー域）において柔軟性を示すため、色材層と受像体と
が密着しやすくなり高記録濃度が得られる。Effect: A resin having a heat deformation temperature of 10 o'C or more prevents thermal fusion in a part of high thermal energy. Copolymerized polyester resin maintains adhesion to the base material and exhibits flexibility in the low density region (low energy region), making it easier for the colorant layer to adhere to the image receptor, resulting in high recording density. .
