本発明は、熱転写記録方法における受像シートに関する
ものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image-receiving sheet in a thermal transfer recording method.

ディスク、写真電送装置などから得られる電気的画像信
号から写真のごときハードコピーの形で画像を再生する
方法が盛んに研究されている。その一つの有力な方法と
して、現在、熱転写画像記録法が注目されている。BACKGROUND OF THE INVENTION Methods of reproducing images in the form of hard copies such as photographs from electrical image signals obtained from video cameras, still video cameras, televisions, video disks, phototransmission devices, etc. are being actively researched. A thermal transfer image recording method is currently attracting attention as one of the promising methods.
熱転写画像記録というのは例えば１龍当り４〜１６ドツ
トのドツト状電気発熱体が一列に並んだサーマルヘッド
に画像情報を含む電気信号を流し、同時に「昇華性染料

と「受像シート」とを重ね合わせたものをヘッドに接触
させながら移動させ、それによりグイシートの染料を画
像情報に従いドツト状に受像シートに転写させることに
よりハードコピーを作成するものである。Thermal transfer image recording is a process in which, for example, an electric signal containing image information is sent to a thermal head in which a dot-shaped electric heating element of 4 to 16 dots per dragon is lined up in a row, and at the same time a sublimable dye layer is applied to one side of a support sheet. "Gui sheet that is coated"
A hard copy is created by moving a superimposed image-receiving sheet and an image-receiving sheet in contact with the head, thereby transferring the dye on the gui-sheet to the image-receiving sheet in dots according to image information.
従来の受像シートは、支持体シート上に単に染料受容層

は、■記録画像の濃度が不均一になる（ムラの発生）、
■ドツト状の白抜けが発生ずる、■画像濃度が全体に薄
（なる、などの欠点があった。Conventional image-receiving sheets simply have a dye-receiving layer on a support sheet, and as a result, the adhesion between the dye layer of the GUI sheet and the dye-receiving layer of the image-receiving sheet is poor, and as a result, for example (a) the dye layer and (b) If minute dust or other foreign matter gets mixed in between the dye layer and the receptor layer during recording, (c) If the surface of the thermal head of the recording device has irregularities or the platen roller If there is any distortion, ■ the density of the recorded image will become uneven (occurrence of unevenness),
There were drawbacks such as: (1) dot-like white spots occurred; and (2) the overall image density was low.
そこで本発明者らは、他の発明者と共に先に、支持体シ

８）。この出願は未だ公開されていないので以下「先願
」と引用する。Therefore, together with other inventors, the present inventors invented an image-receiving sheet in which an elastic layer and a dye-receiving layer were sequentially laminated on a support sheet, and filed a patent application (Japanese Patent Application No. 60-29631).
8). Since this application has not yet been published, it will be referred to as the "prior application" below.

が次第に下にある弾性体層に垂直に移行し、かつ移行し
た染料が今度は弾性体層の中を水平方向に拡散すること
にあることを突き止めた。As a result of intensive research to solve the above problems, the present inventors found that the cause of image blurring was that the dye transferred to the dye-receiving layer gradually migrated perpendicularly to the underlying elastic layer. It was discovered that the dye now diffuses horizontally within the elastic layer.
そこで、更に研究を進めた結果、本発明者らは、水平方
向に拡散した染料を見えなくするため、染料受容層と弾
性体層との間に隠蔽層を設けて遮蔽してやればよいこと
を着想し、本発明を成すに至った。As a result of further research, the inventors of the present invention came up with the idea that in order to make the horizontally diffused dye invisible, a concealing layer could be provided between the dye-receiving layer and the elastic layer. However, the present invention was accomplished.
従って、本発明は、支持体シート上に弾性体層、隠蔽層

転写ムラが生じ、結果として鮮明な画像を得ることがで
きなくなるからである。The mold release agent is used to prevent the receptor layer from adhering to the dye layer on the Gui sheet during recording, and is selected from, for example, silicon compounds, fluorine compounds, higher fatty acids and their metal salts, surfactants, etc. , those having good compatibility with the dye-receiving resin described above are preferred. This is because if the compatibility is poor, the receiving layer becomes non-uniform, the surface loses its luster and uneven dye transfer occurs, and as a result, it becomes impossible to obtain a clear image.

．． An amount of 5 parts by weight is preferred. When it is less than 0.01, it tends to fuse with the dye layer, and when it is more than 0.5, the density of the transferred image decreases.
