Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、昇華性染料を含有した転写層を有する熱転
写記録媒体と組合せて使用される昇華転写用受像媒体に
関する。The present invention relates to a sublimation transfer image receiving medium used in combination with a thermal transfer recording medium having a transfer layer containing a sublimable dye.
近年、フルカラープリンターの需要が年々増加し、こ
のフルカラープリンターの記録方式として電子写真方
式、インクジェット方式、感熱転写方式等があるが、こ
の中で保守が容易、騒音が無い等により感熱転写方式が
多く用いられている。In recent years, the demand for full-color printers has been increasing year by year, and the recording methods of these full-color printers include an electrophotographic method, an ink jet method, and a thermal transfer method. Of these, the thermal transfer method is often used because of easy maintenance and no noise. Used.
この感熱転写方式は、熱溶融性物質中に着色剤を分散

部分のインクを受像シート上に熱溶融転写又は昇華移行
させて画像形成する記録方式である。This thermal transfer method is based on a thermal transfer recording medium (color ink sheet) in which a colorant is dispersed in a heat-fusible substance or an ink layer in which a sublimable dye is dispersed in a resin binder is provided on a substrate. An image receiving medium (image receiving sheet) is superimposed on the ink layer surface, and thermal energy controlled by an electric signal of a laser, a thermal head, or the like is applied from the recording medium side, and the ink in that portion is thermally melt-transferred or sublimated onto the image receiving sheet. This is a recording method for forming an image by shifting.
そしてこの感熱転写記録方式は、使用される記録媒体
の種類によって熱溶融転写型と昇華転写型とに大別され
るが、特に後者は原理的にサーマルヘッド等からの熱エ
ネ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。The thermal transfer recording method is roughly classified into a heat-melt transfer type and a sublimation transfer type according to the type of recording medium to be used. Has the advantage of being able to easily obtain a halftone because of sublimation in a monomolecular state and to be able to control the gradation at will, and is considered to be the method most suitable for a full-color printer.
但し、この昇華型熱転写記録方式は、記録用サプライ
としてカラーインクシートを用い、画像信号により選択
的に加熱記録を行なうため、１枚のフルカラー画像を得
るために、イエロー、マゼンタ、シアン、（ブラック）
のインクシートを各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, in this sublimation type thermal transfer recording system, a color ink sheet is used as a recording supply, and heat recording is selectively performed by an image signal. In order to obtain one full-color image, yellow, magenta, cyan, (black) )
This method has a drawback that the running cost is high because the ink sheets are used one by one and discarded even if there is an unused portion thereafter.
そこでこの欠点を改善するために、受像シートの速度
をインクシートの速度のｎ倍（ｎ＞１）にして、両シー
トを走行させた状態で繰返し印字するｎ倍モード法が近
年行なわれている。このｎ倍モード法はインク層の前の
回の使用部分と後の回の使用部分との重なりを少しづつ
ずらす相対速度方式によって多数回印字を行なうもので
ある。Therefore, in order to improve this drawback, an n-times mode method in which the speed of the image receiving sheet is set to n times (n> 1) the speed of the ink sheet and printing is repeated while both sheets are running has been performed in recent years. . In the n-times mode method, printing is performed a large number of times by a relative speed method in which an overlap between a used portion of the ink layer before and a used portion of the ink layer is gradually shifted.

でなく、特にｎ倍モード法では、インクシートと受像シ
ートとの間に強い摩擦力が加わるため、記録時に、融着
を起したり、シートが破損したりすることがあった。In the conventional sublimation transfer recording method, a dye receiving layer made of a thermoplastic polyester resin or the like having a strong dyeing property to a sublimation dye is formed on a substrate (paper, synthetic paper, plastic film, etc.) as an image receiving sheet. Things have been used. However, the conventional image receiving sheet is not sufficiently peelable, and in particular, in the n-fold mode method, a strong frictional force is applied between the ink sheet and the image receiving sheet, so that during recording, fusion occurs or the sheet is damaged. Or something.
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
可能な、剥離性に優れた昇華転写用受像媒体を提供する
ことを目的とする。Accordingly, an object of the present invention is to provide a sublimation transfer image receiving medium having excellent releasability, which can be used in an n-fold mode method requiring even higher releasability than a normal sublimation type thermal transfer recording system. .
