被転写紙平滑度FIELD OF INDUSTRIAL APPLICATION The present invention relates to improvements in thermal transfer sheets, and more particularly, to thermal transfer sheets that provide high-quality printing even on transfer paper with low surface smoothness. [Prior Art 1] When printing output from a computer or word processor by a thermal transfer method, a thermal transfer sheet having a heat-melting ink layer provided on one side of a base film and a thermal head are used. Conventional thermal transfer sheets use a 10-20μ thick paper such as capacitor paper or paraffin paper, or a 3-20μ thick plastic film such as polyester or cellophane as a base film, and pigments are added to the wax. It is manufactured by coating a layer of mixed hot-melt ink. Although the thermal transfer method can print on plain paper,
Not all plain paper can print clearly.
High-quality paper or coated paper that has been subjected to Bekk smoothness rendering to improve the smoothness of the transfer paper provides the best printing, and sufficient print quality can be obtained even with high-quality paper for about 50 seconds. But 5
If a transfer paper with a low smoothness that does not reach 0 seconds is used, the sharpness of the print will deteriorate. This is because when paper has a highly uneven surface, the pressing pressure of the thermal head does not allow the ink surface to come into complete contact with the paper, and areas where there is no contact result in poor transfer. Problem to be Solved by the Invention 1 The purpose of the present invention is to improve the above-mentioned drawbacks of the conventional heat-sensitive transfer sheet, and to provide a heat-sensitive transfer sheet that provides high-quality printing even on transfer paper with low surface smoothness. Our goal is to provide the following. Structure of the Invention [Means for Solving Problems 1] The heat-sensitive transfer sheet of the present invention is characterized in that it has an ink support layer on the heat-melting ink layer provided on the base film. [Effect 1] The ink support layer on the hot-fusible ink layer is heated by the thermal head and transferred onto the transfer paper while maintaining a film state, and comes into contact with the convex portions of the convex and concave portions of the transfer paper. It adheres there and closes the recesses as if by building a bridge, resulting in the effect that the surface of the paper, at least in the area to be printed, is smoothed. In this way, good printing can be performed even on paper with low smoothness. [Embodiment] As the base film, commonly used plastic films such as polyester, polypropylene, cellophane, acetate, and polycarbonate, and papers such as condenser paper and paraffin paper are used. Polyester film is best. The heat-melting ink is prepared by blending carbon black, EVA, paraffin wax, carnauba wax, etc. The appropriate amount of heat-melting ink to be applied is a thickness of 3 to 8 microns in order to stably perform high quality printing. The material for the ink support layer is a plastic that has a melting point in the range of 40 to 150°C and has the ability to form a film so that it can be melted by heating with a thermal head and support the ink on the transfer paper. Use the one selected from Specifically, polycaprolactam, polyamide, polystyrene, acrylic resin, etc. are suitable. It is recommended to add an appropriate amount of extender pigment to the ink support. This is because printing can be prevented from bleeding or trailing. The particle size of the extender pigment is not suitable if it is too large, and it is desirable that the average particle size is 5 μm or less. Suitable as extender pigments are inorganic fillers such as silica, talc, calcium carbonate, precipitated barium sulphate, alumina, titanium white, clay, magnesium carbonate, carbon black or tin oxide. If the amount of the ink support agent is less than 5% by weight of the composition, the effect will be poor, while if it exceeds 30%, the dispersibility will decrease, making it difficult to adjust the ink, or the coated material will be separated from the base film. Since it may easily fall off, it is best to add it in a range of 5 to 30% by weight. When the thickness of the ink support layer is less than 1 μm, the ink support effect is insufficient, and when it exceeds 4 μm, there is a tendency for printing to bleed. On the base film, it is preferable that the heat-fusible ink layer is 2 to 4 microns, the ink support layer is 1 to 4 microns, and the total is about 3 to 8 microns. When a plastic film is used as the base film, it is preferable to provide a layer to prevent sticking to the thermal head on the other surface, that is, on the side opposite to the ink surface and in contact with the thermal head. The anti-sticking layer basically includes a heat-resistant resin and a substance that functions as a heat release agent or a lubricant.
Heat-resistant resins include synthetic resins with a glass transition point of 60'C or higher, or thermoplastic resins with OH or COOH groups, mixed with a compound having two or more amino groups, or diisocyanate or triisocyanate. Those that have undergone crosslinking and curing are preferred. Thermal mold release agents or lubricants include those that melt when heated, such as waxes and amides, esters, and salts of higher fatty acids, and those that are useful while remaining solid, such as fluororesin and inorganic substance powders. There is something. Thermal transfer generally produces glossy and beautiful prints, but on the other hand,
Matte printing may be desirable as it may make the document difficult to read. Several technologies have been developed to meet such demands, including those that use a heat-sensitive transfer sheet with a matte layer on the base film and coated with heat-melting ink, and those that use a matte layer on the base film itself. (Japanese Patent Application Nos. 58-208306 and 2008 proposed by the applicant)
No. 8307 is an example of these) can also be applied in implementing the present invention. Example 11 The following raw materials were blended (1 part is all parts by weight) to prepare a hot-melt ink and an ink support agent. (Thermofusible ink) Carbon black “Diablack G” (Mitsubishi Kasei)
15 parts ethylene/vinyl acetate copolymer rEVΔflex 310j (Mikata Polychemical)
8 parts Paraffin wax [Paraffin 150°FJ (Nippon Seiro) 47 parts Carnauba wax 30 parts (Ink support agent) Polycaprolactam [Ri'Icel PCL 11] (Daicel Chemical) 30 parts Ethyl acetate
The above heat-melt ink was applied to a thickness of 3μ on a base film made of 70 parts polyester.
A thermal transfer ribbon was prepared by coating the ink support to a thickness of 2 microns. This ribbon was used in a commercially available thermal transfer printer, and the transfer properties were examined using plain paper with various smoothness as transfer paper. Transferability was measured by measuring the degree of ink adhesion using a halftone dot analyzer [Erea Duck 1500j (Konishi Roku Photo Industry), and expressed as area dot %. When the area dot % is 80 or more, it can be said that the printing is of sufficiently high quality for visual perception. The results are shown in the table below. For comparison, heat-melt ink 5 was used without applying an ink layer.
The results obtained when using a transfer ribbon having only a μ layer are also shown. Transfer paper smoothness 4.6 seconds 10.1 seconds 33.1 seconds 52.1 seconds Example 181.2% 85.3% 86.7% 89.1% Comparative example 47.9 54.1 66.6 81
．． 6 In the case of a comparative example that corresponds to a conventional thermal transfer ribbon, good printing is possible with high-quality paper with a smoothness of 50 seconds or more.
Paper with low smoothness deteriorates the quality of the stamp. In contrast, in the embodiment of the present invention using a transfer sheet having a layer of ink support, even paper with considerably low smoothness can be
Capable of high quality printing. Example 2 The same procedure as in Example 1 was carried out except that the following formulation was used in which an extender pigment was added to the ink support agent of Example 1. (Ink support agent) [Daicel PCLHIJ (above) 30 parts silica "Eroseal 0K-412J (Japan Aerosil) 5 parts ethyl acetate 65 parts The transferability was further improved as shown below, and the printing quality was further improved.
