用いられている。[Prior art] 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, inkjet methods, and thermal transfer methods. Thermal transfer method is often used.
この感熱転写法は基体上に、熱溶融性物質中に着色剤を
分散するか、又は樹脂結着剤中に昇華性染料を分散した

クを受像シート上に熱溶融転写または昇華移行させて画
像形成する記録方法である。This thermal transfer method uses a thermal transfer recording medium (so-called color ink sheet) that is formed by providing 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 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 transfer or sublimation transfer the ink in that area onto the image-receiving sheet. This is a recording method for forming.
そしてこの感熱転写記録法は使用される記録媒体の種類

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、か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
した方法と考えられる。This thermal transfer recording method is roughly divided into thermal melt transfer type and sublimation transfer type depending on the type of recording medium used.
In particular, the latter has the advantage of being able to easily obtain intermediate tones because, in principle, the dye sublimates in a monomolecular form in response to thermal energy from a thermal head, etc., and it is possible to control the gradation at will. However, it is considered the most suitable method for full-color printers.

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 thermal transfer recording method uses one each of yellow, magenta, cyan, and (black) ink sheets and performs selective thermal printing on each ink sheet to obtain one full-color image. After that, even if unused parts remain, they are discarded, which has the disadvantage of high running costs.

）にして両シートを走行させた状態で繰返し印字する０
倍モード法の２つの方法である。In order to overcome this drawback, in recent years a method has been adopted in which the same ink sheet is used repeatedly to perform printing and recording many times. Specifically, the constant speed mode method involves repeatedly printing while the ink sheet and image receiving sheet are running at a constant speed, and the method in which the speed of the image receiving sheet is n times the speed of the ink sheet (n>1
) and print repeatedly with both sheets running 0
There are two double mode methods.

９８７年１１月）。The latter 0x mode method performs printing multiple times using a relative speed method in which the overlapping portions of the ink layer used in the previous and subsequent times are shifted little by little. Note that in the 0x mode method, it goes without saying that the larger the n value, the more advantageous it is in terms of cost. In this multi-time recording method using the 0x mode method, a part of the unused portion of the ink layer is supplied each time printing is performed, so the multiple recording method using the constant-velocity mode method, which is simply a repeated use of the used portion, is necessary. Compared to the repeat recording method, it has the advantage of reducing the variation in the amount of remaining ink due to the recording history (IEICE Transactions Cvol.
J70C, No, 11. pp. 1537-1544, 1

であった。However, in the sublimation thermal transfer recording method, the sublimation and evaporation reactions are basically zero-order reactions, and even in the 0x mode method, even though the ink layer contains a dye that can withstand multiple uses. , as the n value increases, that is, as the relative speed of the recording medium decreases, the transfer density, especially in high image density areas, decreases, making it difficult to perform satisfactory printing multiple times.

転写体及び記録方法を提案した。Therefore, the present inventors overlaid an image-receiving sheet on the ink layer of an R-flower type thermal transfer recording medium, which has an ink layer in which a sublimable dye is dispersed in particle form in a resin binder on a substrate. A sublimation-type thermal transfer member that performs thermal printing from the recording medium side while running the two under the conditions of [Speed of the recording medium] and sublimation-transfers the dye in the ink layer of that part onto the image receiving sheet. A recording method was proposed.

The image (especially in low-density areas) is grainy, and uniform image quality cannot be obtained.

法である。[Means for Solving the Problems] The structure of the present invention for solving the above problems is such that a receiving layer is provided on a substrate having a polyethylene terephthalate film on at least the surface, and the polyethylene terephthalate film has minute air bubbles. An image receptor, which is a film, and a transfer body, in which an ink layer containing a heat sublimable dye is provided on the substrate, are overlapped, and the speed of the image receptor/speed of the transfer body>1 or the feed amount of the image receiver/the feed amount of the transfer body This is a sublimation type thermal transfer recording method in which thermal printing is performed from the transfer body side under the conditions of 1.
