て近年特に注目を浴びてきている。In recent years 1. Various non-impact type recording devices have been put into practical use. In particular, the thermal recording device 1q requires maintenance work 11υ.
V+V is used as an output device for information processing etc. because it eliminates noise, is noiseless and harmless, and has a simple device structure.
F' is expanding. For example, facsimile, 'l'i
This type of thermal recording device is increasingly being used as a printing means for output in peripheral terminal printers for i-calculators. There are two main types of thermal recording methods: chemical coloring type and transfer type. However, many chemically colored types are easily erased with plasticizers, solvents, adhesive tapes, etc., and they also have disadvantages such as easy additional printing and falsification, making them unsuitable for securities, legal documents, etc. Met. On the other hand, the transfer type has attracted particular attention in recent years as a method for overcoming the above-mentioned drawbacks.

せることにより行なっている。As shown in FIG. 1, the thermal recording sheet (3) is attached to the transfer mold jl used in the conventional transfer type thermal recording method by sealing it with cellophane or parchment paper, etc. 11'; and a solid ink layer (2). 1. The solid ink layer (2) is made of carnauba wax or polyethylene glycol (with a melting point of 80° C. to 120° C.), polyethylene glycol, etc. (caust and dye are dissolved in a solvent, and the solid ink layer (2) is applied to a thickness of about 4 μm on the above-mentioned sealing JII. It is formed by coating with a wire paper or the like and drying.Thermal recording is performed by heating to dissolve the solid ink layer (2) and transferring it onto ordinary paper.

の転写型感熱記録用シートの開発が望まれていた。However, in order to improve resolution and sensitivity in the conventional transfer type thermal recording method, solid ink F! The thickness of i21 is 4
Generally, the thickness is about μm. For this reason, transfer can be performed only once, and for example, for recording on one A4 size sheet, it is necessary to use one A4 size transfer type heat-sensitive recording sheet. Therefore, it has been desired to develop a transfer-type heat-sensitive recording sheet that can be used repeatedly and has a high resolution.

字部の反射濃度が転写回数と共に低下する欠点がある。In order to overcome the above drawbacks, a method has been proposed in which a carbon blank is dispersed in solid ink (2) to suppress the amount of ink elution. However, this method has the drawback that the carbon blank itself may be transferred onto the paper, and the reflection density of the printed area decreases with the number of transfers.

There is a dye transfer type heat-sensitive recording sheet described in Japanese Patent No. 8793. This method allows multiple transfers until the sublimable dye in the sheet is used up, but the sublimation temperature of the sublimable dye is high, and the temperature is 150°C to 200°C.
Because of the above, the sensitivity was poor.

トの感度にも効いていることがわかった。FIG. 4 also shows that plain paper is used as the recording medium, 8 parts by weight of PVA and 8 parts by weight of azo disperse dye (manufactured by Hodogaya Chemical Co., Ltd., trade name 0H-B) are used as the resin composition of the transfer type heat-sensitive recording sheet.
0,6,10 respectively with 20 parts by weight of glycerin
, 11.14 parts by weight of surfactant (span 40, melting point 4
7°C) is used. In this case, the method for preparing the transfer-type heat-sensitive recording sheet and the method for transferring were the same as in Example 1 described below. As can be seen from the figure, it is preferable to add 1 to 20 parts by weight per 8 parts by weight of the resin (preferably 14 parts by weight plus 14 parts by weight for a span of 4 degrees and 2 degrees). There is no effect if the single layer I is less than 4 parts, and if it is more than 20 parts, the background fog is large. In other words, when a surfactant is added, a favorable result has been obtained in which the resin is not transferred to the recording medium even if the transfer-type heat-sensitive recording sheet is heated above the glass transition temperature (contrary to the conventional glass transition temperature). It has been found that the addition of the agent also has an effect on the sensitivity of the transfer-type heat-sensitive recording sheet.

The OD when a 0-weight weight is placed on it for 5 seconds is at most 06, but this is compared to Solpicun Monooleate (trade name Span 80), a surface-elevating agent.

として用いる。For reference, the recording medium used for the transfer-type heat-sensitive recording sheet of the present invention is, for example, plain paper, and in the case of a plastic sheet with a smooth surface, rubbing the surface will settle the transfer print, so the surface is used as a rough embossed ticket.

度に比例するので階調性が得られるのである。The transfer-type thermosensitive recording sheet of the present invention constructed as described above is superimposed on a recording medium such as plain paper, and the conditions are as follows: an applied voltage of 16 V, a pulse-to-pulse wave number of 100 Hz, a pulse application time of 2 ms, and a paper feed speed of 16 g/S. When printing with a thick-film head, the heat generated by the thermal head reaches the resin material layer through the sealing film, and when heated, the dye is dissolved in the dye-dissolving material and surfactant, and these liquids are dissolved. The mixture is transferred to the recording medium surface. At this time, only a portion of the mixture is eluted due to its adsorption to the resin, so it can be used repeatedly, and since the amount of dye dissolved is proportional to the temperature, gradation can be obtained.
