転写方法か行われている。(Prior art) Various thermal transfer methods have been known in the past, but among them, a thermal transfer sheet is prepared by using an elevating/IW dye as a recording agent and supporting it on a base sheet such as paper to form a thermal transfer sheet. A transfer material that can be dyed with a dye, such as polyester woven fabric, is coated with thermal energy lj in a pattern from the back side of the thermal transfer sheet to transfer the ascending dye to the transfer material.

成されることを知見して本発明を完成した。As a result of intensive research in response to the strong demands of the industry as described above, the inventor of the present invention found that conventional polyester weaving was possible! In sublimation printing methods such as No. 6, the surface of the woven fabric is not smooth, so the thermal transfer sheet and the woven fabric, which is the material to be transferred, do not come into close contact with each other. ζ Color or vaporizability (i.e., the ability to migrate through the space that exists between the thermal transfer sheet and the woven fabric) were essential conditions, but polyester sheets with smooth surfaces and surface treatments were also required. When paper or the like is used as a material to be transferred, the thermal transfer sheet, material to be transferred, and power source are in close contact with each other during thermal transfer, so sublimation and vaporization of the dye are not the only absolute requirements; The ability of the dye to transfer through the interface due to heat T1 is also extremely important, and the thermal transferability of such an interface varies greatly depending on the chemical structure of the dye used, the substituent, or its position.
By knowing that the molecular weight of the dye is high and selecting a dye with an appropriate molecular structure,2 even if the dye has a high molecular weight, which is considered to be unusable according to conventional academic knowledge, It has been found that this material has good heat transfer properties. By using a thermal transfer sheet that supports such dyes, the dyes used can be easily transferred to the transfer material even when thermal energy is applied for an extremely short period of time, resulting in high density and excellent fastness. The present invention was completed based on the finding that a recorded image having a unique character can be formed.

Compared to the Qi-raising dyes (molecular IA of about 150 to 250) used in thermal transfer sheets, it has a significantly higher molecular weight: Despite having an IK of 4F, it has a specific structure, and has a specific structure. Because it has a substituent at the position of It's not something to bleat out.

There is no need to dye other articles, and the problems of the prior art are solved.

This kind of excellent effect, which cannot be imagined with conventional technology, is especially noticeable when the dye-receiving part of the transferred material is made of a material such as polyester. It is also thought that it is fixed in the polyester by some action due to the correlation with the ester bond which is the group.
