る熱転写記録方法は公知である。Conventional structure and its problems A recording medium and a thermal transfer recording sheet having a layer of recording material to be transferred to the medium on one side of a heat-resistant sheet-like base are used. Thermal transfer involves selectively heating and writing onto the recording material from the other side, that is, the back side, of a sheet-like substrate using a thermal recording head while the medium is in pressure contact, and selectively transferring and recording the recording material onto the recording medium. Recording methods are known.

では、転写ムラが多い。Thermal transfer using this thermal transfer sheet 1 is performed by pressing the recording medium 4 against the conventional thermal transfer sheet 1 at a constant pressure 5, and then transferring it from the other side 2b of the sheet-like substrate 2 on which the recording material layer 3 is not formed. , the recording material layer 3 is selectively subjected to heating writing 6 by the thermal head, melting from the side of the recording material layer 3 in contact with the sheet-like substrate 2, and the thickness direction of the recording material layer 3 is melted according to the thermal energy supplied by the heating writing 6. Melting progresses to
Only when the surface 3a in contact with the recording medium 4 is melted,
Almost all of the recording material 7 that is transferred to the recording medium 4 and melted in the layer thickness direction is transferred and recorded. At this time, in order to always transfer the same amount of melted recording material 7 to the same recording medium 4 according to the supplied thermal energy without causing transfer unevenness, contact between the recording medium 4 and the recording material layer 3 is required. The transfer unevenness is greatly affected by the unevenness, but since the recording material is in a state of melting and low viscosity, the transfer unevenness is mainly influenced by the surface condition of the recording medium 4 to which transfer is performed and the constant pressure 10 at the time of contact. However, when a thermal head is used for temperature-elevated writing 6, the constant pressure of 1° is preferably set to 2.0Kii'/c4 or less due to physical strength problems of the thermal head, and it is also preferable that Even if a sufficient constant pressure 1o is obtained using another temperature-raising writing method 6, the pressure may cause the melted recording material 7 to protrude from the recording pixels, or even the unmelted recording material to be transferred. It looks like it's coming. Therefore, conventionally, the recording medium 4 used has been subjected to a surface treatment such as calendered paper or coated paper, and the surface smoothness of the generally used recording medium 4 is low, for example, Beck smoothness is 200 seconds. There is a lot of transfer unevenness with vertical paper.

録画像の品質か著−しく低下する。Furthermore, if these recording media 4 with low surface smoothness are used, it is impossible to cope with multi-gradation recording applications such as video image recording, which is currently expanding by the above-mentioned thermal melt transfer method, and the density pattern method, dithering, etc. Analog gradation is achieved by creating multi-gradation density recorded images by binary density recording and by providing holes penetrating the recording material layer and letting the recording material with reduced viscosity out from the sheet-like substrate side through the holes to the recording medium side. The quality of recorded images deteriorates significantly.

Before transfer recording, at least the entire or part of the surface of the recording medium to be recorded is coated with a surface smoothing agent that increases the smoothness of the surface, and after increasing the smoothness of the recording medium surface, the above-mentioned transfer is performed. This is a thermal transfer recording method for recording.

A heat-resistant film such as polyethylene terephthalate (PET) of about 5 μm or a paper such as capacitor paper of about 5 to 50 μm is coated on the surface 2a side of the sheet-like substrate 2 with a film whose viscosity decreases and transferability increases as the temperature rises, for example, hot film. The recording material layer 3 is formed by layering a recording material composed of about 80 parts by weight of a melt solid material and about 20 parts by weight of a pigment coloring material to a thickness of about 1 to 15 μm.

The front surface 3a of the recording material layer 3 of the thermal transfer recording sheet 1 is brought into contact with the front surface 11, and at this time, the thermal head 8 is applied to the back surface 2b of the sheet-like substrate 2 of the thermal transfer recording sheet 1 on which the recording material layer 3 is not formed. Further, a feed roller 13 made of a metal or rubber material, etc. rotating in the direction of an arrow 12 is applied from the back side 4b of the recording medium 4 with a constant pressure 5 by a pressure welding device 14 such as a spring, so that the recording medium 4 and the thermal transfer recording sheet 1 are pressed together. In this state, temperature increase writing is performed on the thermal head 8 by the temperature increase control circuit 9.
The molten recording material 7 is made to grow and thermally transferred to the recording medium 4 side, and is moved by the feed roller 13 as shown by the arrow 12''-a.

録像１５を得る。12-b direction of the recording medium 4. By feeding the thermal transfer recording sheet 1 and separating these two sheets, a recorded image 15 is obtained by the recording material transferred to the recording medium 4 side. The surface 4a of the recording medium 4 during transfer is made smoother by the surface smoothing agent 10, and uneven contact between the surface 11 and the surface 3a of the thermal transfer recording sheet is suppressed, and the constant pressure 5 is not increased. As a result, thermal transfer recording with less transfer unevenness is possible without changing the mechanical load on the thermal head 8. Furthermore, in order to improve the smoothness of the recording medium 4, even if paper with a Bekk smoothness of 500 seconds or less is used, it is possible to improve the Bekk smoothness by calendering, etc. It is possible to perform thermal transfer recording with as little transfer unevenness as when recording is performed on the recording medium 4 for 600 seconds or longer using a conventional thermal transfer recording method. Furthermore, since most of the recording material is transferred onto the surface smoothing agent, the influence of the material of the recording medium 4 is small, and a substantially constant recorded image 15 is obtained regardless of the recording medium 4.

上が好ましい。The surface smoothing agent is selected from waxes such as paraffin, microcrystalline wax, and carnauba wax, resins such as petroleum resins, polyethylene, and polystyrene, and mixtures thereof. When the substrate of the head 8 reaches a temperature of 50'C4, the viscosity of the surface of the surface smoothing agent decreases and part of it is peeled off when it comes into contact with the recording material layer 3. In order to avoid the fog transfer that occurs, the melting point or softening point of the surface treatment agent is 60°C or higher, preferably 70°C or higher.

The solution 16 is applied to at least the surface 4a of the recording medium 4 to be recorded via the application roller 19, and at the same time, the solution 16 is applied while applying a constant pressure 22 to the pressure roller 2o using a second pressure contact device 21 such as a spring. There are solvent coating methods, spray methods using a sprayer etc. with the above-mentioned solution 16, and hot melt coating methods in which the surface smoothing agent 10 is heated to lower its viscosity before being applied.
By coating the entire surface 4a of the recording medium 40 or a portion thereof, the smoothness of the surface 11 to be recorded is increased.

行なわれる。In addition, a thermal transfer recording sheet or the like that enables analog gradation recording by providing holes penetrating the recording material layer and passing the recording material whose viscosity has decreased through the holes, etc., is used. When performing halftone recording, most of the temperature increase control is performed by pulse width control, but the maximum thermal energy required to transfer the recording material is still greater than the maximum pulse width, and it is necessary to transfer the surface smoothing agent. Therefore, the temperature increase control circuit 9 must be changed. Therefore, in order to form the surface treatment agent film 10a without changing the conventional temperature increase control circuit 9, the surface smoothing agent is made of the same material as in the first embodiment, and is of the same level or lower than that of the recording material. The surface treatment agent film 10a is formed at least below the maximum thermal energy or maximum pulse width required for transferring the recording material.

１６μｍが選ばれる。However, if it is too thick, it will require a lot of energy to be supplied during thermal transfer, so the thickness of the surface smoothing agent layer 23 should be 0.6 to 0.6.
16 μm is chosen.
