Abstract

PURPOSE:To obtain a heat sublimation-type transfer recording medium wherein a transfer image without density fluctuation and absence of dot can be obtd. by providing a dye layer contg. a sublimation dye, a resin binder and a higher fatty acid on a base. CONSTITUTION:A dye layer contg. a sublimation dye, a resin binder and a higher fatty acid (e.g. oleic acid) is provided on a base. The dye is dispersed in a particulate shape in the resin binder. In addition, in a heat transfer recording medium wherein two dye layers each contg. a sublimation dye and a resin binder are laminated and the amt. of dye transfer of the dye layer being closer to the base is at least the amt. of dye transfer of the surface dye layer, the higher fatty acid is incorporated at least in the dye layer being close to the base. In addition, heat loading recording is performed by laminating the heat transfer recording medium and an image receiving sheet and setting the carrying speed of the recording medium slower than the carrying speed of the image receiving sheet. As the result, it is possible to obtain a heat sublimation transfer recording medium wherein a transfer image without density fluctuation absence of dot can be obtd.

Further, in the thermal transfer recording system, one of the transfer layers is used.
There are a so-called one-time recording method in which transfer can be performed only once from a portion, and a multiple recording method in which a plurality of transfer recordings are performed from one portion of the transfer layer. In this multi-time recording method, heat recording is performed while the recording medium and the image receiving sheet are overlapped and both are transferred at a constant speed, and the recording medium after being used once and the new image receiving sheet are overlapped. The so-called n times mode (recording medium transfer speed / image receiving speed), in which heat application recording is performed a plurality of times, and the recording medium and the image receiving sheet are overlapped and the transfer speed of the recording medium is slower than the transfer speed of the image receiving sheet for recording A sheet transfer speed = 1 / n) recording method is known.

However, when the above-mentioned thermal sublimation transfer recording medium is used in a multi-time recording system in which one portion of the medium is used for a plurality of times of recording, density unevenness and dot omission occur, and especially n In the double mode recording method, density unevenness in a large area or dot omission may occur. The present inventor diligently studied the cause of this defect,
It was found that the surface of the transfer layer had minute irregularities. In the n-times mode recording method, when an actual image is heat-applied and recorded, the uneven defect portions on the surface of the transfer medium are continuously used (heat is applied), so that the size becomes n-times and is recorded on the image receiving medium. it is conceivable that.

As an example of the multi-time recording system, a plurality of transfer recording media used for one-time recording by superimposing heat recording so that the dye layer of the transfer medium and the dye receiving layer of the image receiving sheet are in contact with each other in the thermal recording section. The method used for thermal recording or the contact superposition of both in the thermal recording section is the same as the previous method, but the transfer speed of the image receiving sheet is n times the transfer speed of the transfer medium (n> 1). There is a so-called n-times mode recording method in which recording is performed quickly, and when one minute portion of the dye layer differs in surface property from another wide portion, it naturally appears as uneven density, In the mode recording method, since one minute portion is continuously affected by the transfer quality on the receiving layer, density unevenness or dot missing in a large portion appears. Therefore, the recording medium of the present invention, which has uniform transferability over the entire surface, is expected to be most effective in the n-fold mode recording method.
