This is a method of recording by instantaneously heating the head 5 from the base material 1 side and transferring the color image 6 to the recording paper 4.0 Conventionally, as a method of manufacturing a thermal transfer ink sheet, thermally melted ink is applied to the base material. There are two methods: a method in which the ink material is coated on the base material 1, and a method in which the ink material is dissolved or dispersed in a solvent and coated on the base material 1. In the former case, when the ink 2 melted by heating is applied onto the base material 1, it immediately cools and hardens, so the ink 2
Also, the substrate 1 must be warmed up while being coated, which complicates the coating equipment.

れが熱伝導を妨げるため、転写感度低下の原因となる。Furthermore, this method cannot be applied if the ink contains ink components that do not melt under heat. On the other hand, according to the latter coating method using a solvent, voids (pores) are generated due to the evaporation of the solvent, which impede heat conduction and cause a decrease in transfer sensitivity.

However, there was a drawback that the characteristics of the ink sheet 3 varied.

て達成される。(d) Structure and object of the invention According to the present invention, after dissolving or dispersing an ink material in a solvent and applying it to a base material, the ink material is heated and melted to remove fine pores formed by evaporation of the solvent. This is achieved by providing a method of manufacturing an ink sheet by filling the ink sheet, characterized in that the method includes a cooling step of performing cooling and solidification after the heating and melting.

いる。The method for manufacturing the thermal transfer ink sheet of the present invention is to dissolve or disperse the ink material in a solvent, apply it to the substrate, heat and melt it to fill the fine voids (holes) created by the evaporation of the solvent, and then cool it. By performing solidification at a constant temperature for a short period of time, each component of the ink is solidified while remaining uniformly dissolved, resulting in an ink sheet with homogeneous properties.

The melting time is about 5 seconds. The water cooling pipe is made of aluminum and has water flowing inside it, so when it is used continuously, the heat accumulated in the water cooling pipe 13 is cooled by the flowing water and the temperature of the water cooling pipe 13 is kept constant. dripping Because it is rapidly cooled at a constant temperature (20'C in the example) by the water cooling pipe 13, the ink material components with high melting points do not solidify as in conventional natural cooling.
Solidifies while remaining uniformly dispersed.
