本発明は、昇華性染料を含有した転写層を有する熱転写

する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an image receiving medium for sublimation transfer, which is used in combination with a thermal transfer recording medium having a transfer layer containing a sublimable dye.
［従来の技術コ
近年、フルカラープリンターの需要が年々増加し、この

用いられている。[Conventional technology] In recent years, the demand for full-color printers has increased year by year, and the recording methods for these full-color printers include electrophotography,
There are inkjet methods, thermal transfer methods, etc., but among these, the thermal transfer method is often used because it is easy to maintain and produces no noise.

せて画像形成する記録方式である。This thermal transfer method uses a thermal transfer recording medium (color ink sheet), which has an ink layer on a substrate, in which a colorant is dispersed in a heat-fusible substance or a sublimable dye is dispersed in a resin binder. ) An image receiving medium (image receiving sheet) is placed on the ink layer surface of the image receiving sheet, and thermal energy controlled by an electric signal from a laser or a thermal head is applied from the recording medium side to thermally melt and transfer the ink in that area onto the image receiving sheet. Alternatively, it is a recording method in which an image is formed by sublimation transfer.
そしてこの感熱転写記録方式は、使用される記録媒体の

ルギーに対応して染料が単分子状で昇華するため容易に
中間調が得られ、且つ随意に階調をコントロールするこ
とが可能である利点を有し、フルカラープリンターに最
も適した方式と考えられる。This thermal transfer recording method is roughly divided into a heat-melting transfer type and a sublimation transfer type depending on the type of recording medium used.The latter, in principle, uses dyes that respond to heat energy from a thermal head, etc. Since it sublimates in a monomolecular form, it has the advantage that intermediate tones can be easily obtained and the gradation can be controlled at will, and is considered to be the most suitable method for full-color printers.

ンクシ一トを各１枚づつ使用し、その後未使用部が存在
しても、破棄するためランニングコストが高いという欠
点を有している。However, this sublimation type thermal transfer recording method uses a color ink sheet as a recording sub-line and performs thermal recording selectively based on image signals. This method has the drawback that the running cost is high because one ink sheet of each color (black) is used, and even if there is an unused portion, it is discarded.
そこでこの欠点を改善するために、受像シートの速度を

る。In order to improve this drawback, an n-time mode method has recently been used in which the speed of the image-receiving sheet is set to n times the speed of the ink sheet (n>1), and printing is repeated while both sheets are running. There is. In this n-times mode method, printing is performed multiple times using a relative speed method in which the overlap between the previously used portion of the ink layer and the later used portion is shifted little by little.

起したり、シートが破損したりすることがあった。E Problems to be Solved by the Invention In the conventional sublimation transfer recording system, the image receiving sheet is a dye receiving layer made of a thermoplastic polyester resin or the like that exhibits strong dyeability against sublimation dyes as a substrate (paper, synthetic paper, Plastic films, etc.) have been used. However, conventional image-receiving sheets do not have sufficient releasability, and especially in the n-times mode method, strong frictional force is applied between the ink sheet and the image-receiving sheet, which may cause fusion or sheet damage during recording. Sometimes it got damaged.
従って本発明は、通常の昇華型熱転写記録方式よりも更
に高剥離性が要求されるｎ倍モード法においても使用可

昇華転写用受像媒体を提供することを目的とする。Therefore, the present invention provides an image receiver for sublimation transfer that has excellent releasability and is capable of recording high image density, which can also be used in the n-times mode method, which requires even higher releasability than the normal sublimation thermal transfer recording method. The purpose is to provide a medium.

昇華転写用受像媒体が提供される。[Means for Solving the Problems] According to the present invention, in an image receiving medium having a dye-receiving layer on a substrate to which a sublimation dye can be dyed, the receiving layer is made of a vinyl chloride resin containing an OH group and an isocyanate compound. There is provided an image receiving medium for sublimation transfer characterized by containing polycaprolactone as a main component.

ない。That is, the image receiving medium for sublimation transfer of the present invention has OH
Since it has a structure in which a dye-receiving layer is mainly composed of a vinyl chloride resin containing groups and an isocyanate compound,
The vinyl chloride resin has excellent properties in dyeability, releasability, light resistance, and storage stability, and further, the releasability is further improved due to the curing reaction between the OH group and the isocyanate compound. Generally, with a hardened receptor layer, the sensitivity decreases and the image density of the recorded image is not sufficient, but in the present invention, since the receptor layer contains polycabrolactone, the image density is high, and the hardened receptor layer Does not reduce effectiveness.

It was applied onto synthetic paper (trade name Yubo PPG-150, manufactured by Oji Yuka Synthetic Paper Co., Ltd.) and dried for 1 minute at a drying temperature of 75°C.
After forming a dye-receiving layer with a thickness of approximately 5μ, the temperature was further increased to 80°C.
The image-receiving medium of the present invention was prepared by storing it for 3 hours and curing it.
