定の印字像を形成させるものである。 As the recording material used in such thermal facsimiles and thermal printers, thermal transfer type recording media are often used, in which a thermal transfer layer mainly consisting of a heat-melting wax and a colorant is formed on a base material by hot melt coating or the like. There is. In such a recording medium, a thermal transfer layer is melt-transferred onto a copy sheet in the form of a printed image by printing using a heating body such as a thermal head, thereby forming a predetermined printed image on the copy sheet.

It has the disadvantages that it lacks in quality, causes misshapen characters during melt transfer, and has weak adhesion strength to the copy sheet, which causes uneven transfer or stains the copy sheet when rubbed.

要旨とする。Structure The present invention provides a thermal transfer recording medium in which a thermal transfer layer containing a colorant and a low-melting point substance as main components is provided on a heat-resistant support, and the low-melting point substance has the following general formula (). The gist of the present invention is a thermal transfer recording medium characterized by containing thermoplastic polycaprolactone having a repeating structure of (where n indicates the number of repeating units).

記録における良好な特性を有している。 The polycaprolactone used in the present invention forms a strong thin film and at the same time has a melting point of 40 to 70°C (determined by the number of repetitions of the unit), which has good properties in thermal transfer recording.

関係を示した。 The polycaprolactone is a polyester resin and is prepared by ring-opening polymerization of ε-caprolactone. Because it has a so-called repeating structure of a single unit of methylene groups and ester groups, it exhibits a melting point despite a higher degree of polymerization than conventional polyethylene terephthalate-based polyesters, and reaches an equilibrium at about 60 to 70°C. Table 1 shows the relationship between average molecular weight (number average molecular weight; the same applies below) and melting point.

For example, one with an average molecular weight of 10,000 is dissolved in an appropriate organic solvent, such as tetrahydrofuran, and then re-melted with ethanol. Precipitation results in a melting point of 59.5-61°C.

Good results can be obtained by adding 5 to 30% of 70,000 to 100,000. Alternatively, styrene-butadiene rubber, ethylene-vinyl acetate copolymer, vinyl chloride-vinyl acetate copolymer, ethyl cellulose, polyvinyl butyral, and other skeleton polyesters having a softening point of about 80 to 110°C can also be used.

からの剥落を防止しえたものである。 The thermal transfer layer of the present invention is made by blending the above-mentioned low melting point substance in a proportion of 99 to 60% and the coloring agent in a proportion of 1 to 40% of the total amount, so that the thermal transfer layer does not adhere easily, which is a drawback of ordinary thermal transfer layers using wax. It has improved strength, prevents the occurrence of crooked characters and scratches, has high melt transferability, and can prevent peeling off from heat-resistant supports.

Carbon tetrachloride, methylene chloride, cyclohexanone,
Ethyl acetate, tetrahydrofuran, dioxane,
After being uniformly dissolved or dispersed in an organic solvent such as dimethylformamide or pyridine, it is applied onto a heat-resistant support and dried. The thermal transfer layer thus obtained can contain a larger amount of colorant than a normal thermal transfer layer using wax,
Therefore, the thickness of the thermal transfer layer can be reduced, and the resulting transferred image also has extremely high clarity.
