[Industrial Field of Application] The present invention relates to the above-mentioned ink used in an image forming apparatus such as a typewriter or a computer printer to transfer a heat-melting ink to a recording paper by heating a thermal head to form an image. The present invention relates to a thermal transfer recording medium that holds heat-fusible ink. [Prior art] Conventionally, this type of thermal transfer recording medium has been formed by coating a base material such as a resin film or high-density paper with a heat-melting ink layer that is solid at room temperature and is a mixture of a binder agent such as wax and a colored pigment. This heat-melting ink layer is pressed against a recording paper and heated by a thermal head, so that the ink in the heated areas is melted and transferred to the recording paper. [Problems to be Solved by the Invention] In such conventional technology, due to sliding or pressure contact between the heat-melting ink layer and the recording paper, the ink is not heated in areas that are not heated by the thermal head. There was a problem in that the particles transferred to the recording paper and stained the recording paper. [Means for Solving the Problems] In order to solve these problems, the present invention has the following features:
In a thermal transfer recording medium in which a heat-melting ink layer is formed in a layered manner on one surface of a film base material, the heat-melting ink layer is formed by dispersing and mixing a colorant in a thermoplastic vehicle that melts when heated by a thermal head. The structure is such that only a lubricant, which is solid at room temperature, is deposited on the surface of the ink layer in contact with the receiving paper. [Function] With the above configuration, the contact friction resistance between the surface of the heat-melting ink layer and the recording paper is significantly reduced. [Effects of the Invention] As a result of exhibiting such an effect, the ink layer in a solid state does not adhere to the recording paper, resulting in the effect that staining of the recording paper is prevented. Furthermore, since the lubricant is deposited on the surface of the ink after being transferred to the recording paper, the printed image does not easily crumble even when rubbed with a finger or the like, and the durability of the printed image can be improved. [Embodiments of the Invention] The lubricant is a heat-fusible substance that is solid at room temperature and is mixed into the heat-fusible ink layer and precipitates when the ink layer solidifies, and is melted by heating with a thermal head. It must have a similar melting point. The amount of lubricant to be used is preferably 1 to 20 parts by weight per 100 parts by weight of the dry weight of the heat-melting ink excluding the lubricant; The entire ink layer becomes crystalline, the adhesion of the ink layer to the substrate is impaired, and the ink layer peels off. In addition, if the amount of lubricant used is too less than this range, the desired effect will not be achieved. Examples of such lubricants include the following. Fatty acid-based lubricant Straight chain saturated fatty acids represented by the general formula: CH 3 (CH 2 ) o COOH (wherein n is an integer from 6 to 28) are preferred. Those with side chains, unsaturated bonds, or other functional groups (-OH, -NH2, etc.) are also effective, but as the number of side chains increases, the amount of precipitation on the surface decreases, so it is necessary to increase the amount added. There is. Typical examples of fatty acid-based lubricants include stearic acid, lauric acid, palmitic acid, behenic acid,
Examples include, but are not limited to, sulgaric acid, lignocene phosphoric acid, melisic acid, montanic acid, cerotic acid, and 12-hydroxystearic acid. Aliphatic dibasic acid lubricant A linear saturated aliphatic dibasic acid represented by the general formula: HOCO(CH 2 ) o COOH (wherein n is an integer of 3 to 28) is preferred. Those having side chains, unsaturated bonds, or other functional groups (-OH, -NH2, etc.) are also effective. Typical examples of aliphatic dibasic acid lubricants include adipic acid, sebacic acid, glutaric acid, pimelic acid, and azelaic acid.
It is not limited to these. Aliphatic Alcohol Lubricants Straight chain saturated aliphatic alcohols represented by the general formula: CH 3 (CH 2 ) o OH (where n is an integer from 10 to 30) are preferred. Those having side chains, unsaturated bonds, or other functional groups (-OH, -NH2, etc.) are also effective. Typical examples of the aliphatic alcohol lubricant include stearyl alcohol, lauryl alcohol, cetyl alcohol, ceryl alcohol, luxel alcohol, etc., but are not limited to these. Fatty acid ester lubricant General formula: CH 3 (CH 2 ) n COO (CH 2 ) o CH 3 (where m and n are integers, and m+n is 10
-35) are preferred. Those having side chains, unsaturated bonds, or other functional groups (-OH, -NH2, etc.) are also effective. Representative examples of the fatty acid ester lubricant include, but are not limited to, ethyl stearate, lauryl stearate, ethyl hebenate, hexyl behenate, and behenyl myristate. Fatty Acid Amide Lubricants Amides and bisamides of the aforementioned fatty acids are preferred. Typical examples of fatty acid amide lubricants include stearamide, lauric acid amide, etc., but are not limited to these. Note that among the compounds represented by the above general formulas, those which are not solid at room temperature are not included in the lubricant referred to in the present invention. In addition to the lubricants exemplified above, any lubricant having the same performance as these may be used, and not only one type of these lubricants may be added, but multiple types may be appropriately mixed and used. . The other components of the heat-melt ink are not particularly limited, and waxes and heat-melt resins similar to those in conventional heat-melt inks are the main components of the binder, and coloring pigments and dyes are the main components of the colorant. It is sufficient as long as it does so. Moreover, conventional materials can be used for the base material and others, and the ink application method and coating thickness may be the same as conventional ones. The components of this heat-melting ink other than the lubricant are the same as those of the conventional ink as described above, so they are not explained in detail, but they are not limited to the following examples. [Examples] Examples 1 to 14 and Comparative Examples 1 to 2 to explain the thermal transfer recording medium of the present invention by giving Examples and Comparative Examples. A heat-melt ink was prepared by dispersing and mixing the lubricant components, and the ink was applied to a thickness of 4μ on a 6μ thick polyester film by hot melt coating to produce a thermal transfer recording medium.

Each of the above-mentioned recording media was cut into a ribbon shape of 20 mm wide and 300 mm long, and the obtained ribbon was overlapped with high-quality paper on the ink layer side, and was cut at a speed of 100 mm/sec while applying a pressure of 100 g/cm 2 . Then, the ribbon was moved linearly with respect to the high-quality paper, and it was examined whether the high-quality paper was stained or not. As a result, in Examples 1 to 14, no stains were observed on the high-quality paper, but in Comparative Example 1, the ink was transferred to the traces of the sample on the high-quality paper and the paper was stained. Furthermore, in Comparative Example 2, the lubricant soaked into the marks left by dragging the ribbon on the high-quality paper. Furthermore, using ribbons newly made from each of the recording media described above, an image was formed on high-quality paper using a word processor equipped with a thermal transfer printer (Canon Word 45 manufactured by Canon Inc.). Although no stains were observed on the paper, in Comparative Example 1, there were linear black marks from dragging the ribbon on the high-quality paper. Furthermore, in Comparative Example 2, the lubricant had soaked into the entire surface of the high-quality paper where the ribbon was in contact with the paper, making it dirty.
