The present invention relates to a heat-sensitive transfer material used.

なる感熱転写材が用いられている。PRIOR ART Thermal recording, which utilizes a color reaction between a colorless or light-colored leuco dye and an organic acid at room temperature, and which has recently been widely used in facsimile printers, has excellent operability and maintainability, but is susceptible to falsification of records. It cannot be prevented, and it easily develops or discolors when exposed to heat, light, or organic solvents, so it has disadvantages such as poor storage stability of records. Therefore, there is a thermal transfer recording system as a thermal recording system that compensates for the above-mentioned drawbacks and takes advantage of the advantages of thermal recording. In such a heat-sensitive transfer recording system, a heat-sensitive transfer material consisting of a base film as a substrate and a heat-melting ink layer is used.

。An image is formed by transferring heat-melting ink to plain paper from this heat-sensitive transfer material and plain paper, such as ordinary high-quality paper. In this recording method, only the necessary amount of ink as a coloring agent is transferred, and since a pigment can be used as the main component of the coloring material in the ink, it is possible to permanently preserve prints.

ｃまで上昇すると言われる。In the thermal transfer recording method, since the ink layer is heated through the base material of the heat-sensitive transfer material, the thermal resistance of the base material becomes a problem. Since the resin film does not contain an air layer, it has low thermal resistance and is advantageous as a base material. On the other hand, the base film that is the base material of the thermal transfer material is required to have heat resistance because it comes into direct contact with the thermal head. For example, the surface temperature of the heating resistor of the thermal head during recording is 700~s o o'
It is said to rise to c.

る。For this reason, in a thermal transfer recording system using a thermal transfer material based on a film, a phenomenon called sticking often occurs, which makes it difficult to convey the thermal transfer material and causes serious problems in recording. This phenomenon occurs because the temperature of the film rises and falls within an extremely short period of time, approximately a few milliseconds, so the base resin film, which is melted by heating, solidifies as the temperature of the heating element falls, resulting in thermal damage. This is a phenomenon caused by adhesion or sticking to the head. This phenomenon becomes more noticeable when the time for which electricity is applied to the thermal head becomes shorter or when the thermal transfer material is transported intermittently.
