耐久性を与えることが出来る熱転写カバーフィルムに関
する。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a thermal transfer cover film, and more specifically, it is capable of imparting durability such as excellent abrasion resistance, chemical resistance, solvent resistance, etc. to thermal transfer images, etc. Regarding the thermal transfer cover film that can be made.
（従来の技術及びその問題点）

に利用される様になっている。(Prior art and its problems) Conventionally, thermal transfer methods have been widely used as a simple printing method.These thermal transfer methods can easily form various images, so the number of printed sheets can be compared. It has come to be used for producing small-sized printed matter, for example, ID cards such as identification cards.
又、顔写真等の如くカラー画像が好ましい場合には、連

及びシアン（更に必要に応じてブラック）の着色熱転写
層を面順次に繰返し多数設けた長尺熱転写フィルムを用
いる熱転写方法が行なわれている。If a color image is preferred, such as a photograph of a face, a large number of colored thermal transfer layers of, for example, yellow, magenta, and cyan (and black if necessary) are repeatedly provided in sequence on a continuous base film. A thermal transfer method using a long thermal transfer film has been used.
この様な熱転写フィルムは大別すると、それらの熱転写
層が加熱によって軟化して画像状に被熱転写材に熱転写

によって熱転写層中の染料が昇華（熱移行）して染料の
みが画像状に被熱転写材上に熱転写する、所謂昇華タイ
プの熱転写フィルムとに大別される。These thermal transfer films can be roughly divided into so-called melt transfer type thermal transfer films, in which the thermal transfer layer is softened by heating and thermally transferred in image form to the thermal transfer material, and thermal transfer films in which the dye in the thermal transfer layer is sublimated by heating. It is broadly classified into so-called sublimation type thermal transfer film, in which only the dye is thermally transferred in the form of an image onto the thermal transfer material.

場合は、文字や数字等の如き画像の形成は容易であるが
、これらの画像は耐久性、特に耐摩擦性が劣るという欠
点がある。When creating ID cards such as identification cards using the above thermal transfer film, it is easy to form images such as letters and numbers with the melt transfer type thermal transfer film, but these images are not durable. In particular, it has the disadvantage of poor abrasion resistance.
一方、昇華転写型の熱転写フィルムの場合には、顔写真

すると、これらに染料が移行したり、画像が滲む等の耐
薬品性や耐溶剤性等に劣るという問題もある。On the other hand, in the case of a sublimation transfer type thermal transfer film, it is possible to form gradation images such as facial photographs, but unlike normal printing ink, the formed image has no vehicle, so it has poor abrasion resistance, etc. In addition, when it comes into contact with card cases, file sheets, plastic erasers, etc. that contain plasticizers, the dye may transfer to them or the image may bleed, resulting in poor chemical and solvent resistance. be.
この様な問題点を解決する方法としては、形成された画

全体が厚くなるという問題がある。A method to solve these problems is to laminate a transparent film on the formed image surface, but this method is complicated to operate, causes the image sheet to curl, and Due to the operation of lamination, it is not possible to use very thin films, and therefore there is a problem that the entire laminated image sheet becomes thick.
従って、本発明の目的は、上記従来技術の問題点を解決

Similarly, a magenta image 7M and a cyan image 7C are transferred to the same area to form a desired color image 7. Next, desired characters, symbols, etc. 8 are similarly printed using a wax ink type thermal transfer sheet. If the sublimation type thermal transfer area and the melting type thermal transfer area are different, the sublimation image may be formed after transferring the wax ink. Furthermore, a transparent resin layer is transferred onto the color image 7 and/or image 8 such as characters using the thermal transfer cover film of the present invention to form a protective layer 2. In this way, a desired card can be obtained.
