式のカラープリンターに好適な記録用紙に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording paper for a thermal transfer printer that performs recording by transfer of heat-melting ink. More specifically, the present invention relates to a recording paper consisting of a base paper and a layer containing a heat-fusible substance, which is suitable for a melt-transfer type color printer.

どを混合して詞龜されている。The transfer section of a printer using the melt transfer method is simply made up of an ink ribbon coated with hot-melt ink, recording paper in close contact with the ink-coated surface, and a thermal head in contact with the non-ink-coated surface. . The principle of melt transfer is that the thermal head is heated in response to an electric signal applied to the thermal head, and the amount of heat is transferred to the ink ribbon, melting the heat-fusible ink on the back side. The molten ink is transferred to the surface of the recording paper, cooled and solidified, and then the recorded paper and the ink ribbon are separated. The heating time of the thermal head is 1
~2 ms, heating temperature is 200-450°C. Hot-melt ink is made by mixing pigments, dyes, etc. with natural waxes such as carnauba wax or synthetic waxes such as ester wax.

が転写効率に関係する。Concerning ink transfer in the melt transfer method, the transfer efficiency is related to (i) the contact area between the paper and the melted ink, the opening, the affinity between the melted ink and the paper surface, and (c) the viscosity of the melted ink at which the ink is easily transferred.

れている。Traditionally, recording paper used in melt-transfer printers is usually - Beck flatter than the original? A high-quality paper having an I# degree (hereinafter simply referred to as smoothness) is used, and its smoothness is required to be 100 seconds or more for monochrome and 300 seconds or more for color.

鮮明な画像を形成することは困難であった。Recently, the importance of color gradation recording has become more and more important, but it has been difficult to form clear images simply by adjusting the smoothness of the high-quality paper due to the amount of color.

ことを見出し７本発明に到達した。As a result of repeated research into increasing the contact area (a) and improving the affinity for recording paper, the inventor found that a specific heat-melting substance, for example a mixture of carnauba wax and ester wax, was added to the surface of the base paper. When a coating layer is provided and this is used as a recording surface, the contact area increases due to the reduction in the porosity of the base paper and the creation of fine pores, and the transfer efficiency improves due to improved compatibility with molten ink. The present invention has been achieved by discovering that the properties are significantly improved.

サイズプレスコートまたはゲートロールで可能である。The melting point or eutectic point of a heat-fusible substance is determined by the temperature of the melting ink that melts when it receives the heat of the molten ink that is transferred as described above. ! The melting point or eutectic point must be high enough to bond IIφ and form a suitable record. As shown in the experimental examples described later, for printers whose ink ribbon has a melting point of 67 to 68°C, a wax mixture with a melting point of 80 to 88°C has the highest transfer efficiency through melt adhesion. It was excellent. A preferred example of a mixture having this eutectic point is carnauba wax 10.

Combination of 0 to 250 parts by weight, Montan wax 1007tf
For example, a combination of part t and 25 to 100 parts by weight of stearic acid amide can be mentioned.1. When a surfactant is used as an emulsifier, it lowers the eutectic point of the mixture, so it is set in the present invention. Melting point (including eutectic point) means the melting point of a layer containing a heat-fusible substance, ie, a coating layer. When a surfactant is added, it is added in an amount of 5 to 10 parts by weight per 100 parts by weight of the heat-fusible substance. An emulsion of a hot-melt material can be coated or impregnated onto the paper surface, up to one, or together with a hydrophilic binder such as polyvinyl alcohol or modified starch. Coating can be done by conventional coating methods such as air knife coating, Mayer barcoating and roll coating, or by size press coating or gate rolls during papermaking.

の場合も印字の溶融接着が作用しないと考えられる。The melting point of the coating layer set in the present invention is determined relative to the melting point of the ink of the ink ribbon. The method for measuring the melting point is based on JIS KOO64. According to the accompanying drawings of the experimental examples described later, the preferred melting point range is 80 to 88°C, and 7
In the melting point range of 8° C. or higher and 93° C. or lower, there is a point where the printed reflection density is at least equal to or higher than that of current high-quality paper (reflection density 1.0). In the present invention, in order for the hot-melt ink to melt and adhere to the coating layer, only the surface of the coating layer needs to be melted by the melting ink. If the melting point of the coating layer is below 78°C, the melting will extend to the inside of the coating layer.
Since the surface of the coating layer does not melt at 3° C. or higher, it is considered that the melt adhesion of the print does not work in either case.

ることが好ましい。The melting point of heat-melting inks used in ink ribbons for thermal transfer printers is usually 60 to 70°C, and several systems based on the same principle are employed. Therefore, the melting point of the layer containing the heat-fusible substance referred to in the present invention is determined relatively, and therefore, in the present invention, the temperature range is 10°C or more and 26°C or less, which is the melting point of the heat-fusible ink. It is preferable.

工層に溶融接着しうるものが選択使用されるので、従来
の記録用紙とは異な夛単なる接着ではない。Since the recording paper for thermal transfer printers of the present invention is coated with a material containing a heat-fusible substance on the surface of the base paper, the porosity of the base paper is reduced and fine pores are formed, resulting in the penetration of molten ink. , diffusion is suppressed and clear images are formed. (2) The heat-fusible material is selected so that the transferred heat-fusible ink can melt and adhere to the coated layer, so unlike conventional recording paper, it is not a mere adhesion.

えうるものである。In conventional recording paper, that is, high-quality paper whose main quality characteristic is smoothness, the transferred heat-melting ink is cooled and solidified on the paper surface, but the seepage and diffusion of the melting ink is unavoidable. Since the present invention has the above-mentioned effects, the sharpness of the image is close to that of film or synthetic paper, and can fully meet the requirements of gradation recording.

．． An emulsion with a solid content of 43% was prepared using an emulsifier with 5 parts by weight. The melting point of the solid content of the emulsion was 84°C. Modified starch (Nichoku Kako, 3800 parts by weight) was added to 100 parts by weight of this emulsion.
) A coating liquid was prepared by adding 100 parts by weight of a 10% solution and 400 parts by weight of water. The solid content of the coating liquid is 8.8% and the viscosity is 2.
It was 15CP at 0°C. Coated on one side of the same oak bond as in Example 2 using a Mayer Percoater, with a dry solid content of 3.
g/lr? I got it. The coated surface was finished with a smoothness of 500 seconds using a super gear render. Barcode printer (
■SATO, M2SO4) printed POS barcodes continuously and issued tickets. The printing density of the recording paper of this example was 0.94, compared to the printing density of 0.78 for the Oak Bond with a smoothness of 300 seconds. There were no misleads caused by breaks in the thin lines of the barcode, and the printed barcodes had sharp, thin lines.
