[Industrial Application Field] The present invention relates to a thermal transfer recording medium used in a transfer type thermal recording method. [Prior Art] In recent years, thermal recording using thermosensitive coloring paper has been widely used in thermal recording devices such as facsimiles due to its excellent operability and maintainability. Thermal transfer recording uses plain paper and an ink ribbon (recording medium) coated with heat-melting solid ink on the base material, separating the functions of heat-sensitive coloring paper.Thermal transfer recording uses almost the same recording energy as thermal recording to achieve image density. It has the characteristics of being able to record with higher contrast and superior contrast, and that it is relatively easy to record in color by preparing recording media of multiple colors and sequentially transferring them onto recording paper. The basic principle of thermal transfer recording is as follows. That is, plain paper is placed on the heat-fusible ink surface of the heat-sensitive transfer material, and the ink is selectively heated with a thermal head from the side of the base material to which the ink is not applied, and is transferred onto the plain paper. Recording is completed when the thermal transfer material and plain paper are peeled off. Wax-type carbon ink with a melting point of 50 to 90°C is generally used as the heat-melting ink for thermal transfer materials. For example, for black ink, those having the following composition are used. Carbon black 15% Dye 5% Toner 3% Parafine wax 35% Carnauba wax 27% Montan wax 10% Rice wax 5% In addition to the above ingredients, use a suitable resin in consideration of the durability and stain resistance of the record. may also be added. In the case of color recording using a thermal transfer recording medium, for example, prepare ink ribbons of each color of yellow, magenta, and cyan, and transfer images of each color sequentially onto recording paper, and overlap them to create the desired color image. can be obtained. In this method, it is possible to obtain a color image by mixing each color, and it is also possible to reproduce the image as a monochromatic image, or to reproduce the image with multiple single colors of each color without mixing each color. . The colorant used in the ink in this case is a transparent or translucent colorant (hereinafter referred to as a transparent colorant) that can express a desired color by overlapping colors.
It is said that it is preferable to use
(See No. 158291). That is, transparent colorants that form yellow include, for example, chrome yellow (yellow lead) and zinc yellow.
Zinc chromate (zinc yellow), lemon yellow (barium chromate), cadmium yellow, naphthol yellow S, Hansa yellow 3G, Hansa yellow G,
One or two types of pigments such as Hansa Yellow GR, Hansa Yellow A, Hansa Yellow RN, Hansa Yellow R, Benzidine Yellow, Benzidine Yellow G, Benzidine Yellow GR, Permanent Yellow NCG, Quinoline Yellow Lake, and dyes such as auramine.
More than one species is used. Transparent colorants that form magenta include, for example, Permanent Red 4R, Brilliant Fast Scarlet, Brilliant Carmine BS, Permanent Carmine FB, Resole Red, Permanent Red F5R, Brilliant Carmine 6B, Pigment Scarlet 3B, and Rhodamine. One or more of pigments such as Lake B, Rhodamine Lake Y, and Alizarin Lake, and paints such as Rhodamine are used. Furthermore, as a transparent colorant that forms cyan,
For example, one or more of pigments such as Victoria Blue Lake, metal-free phthalocyanine blue, phthalocyanine blue, and fast sky blue, and dyes such as Victoria Blue are used. Here, the pigments forming yellow, magenta, and cyan refer to pigments that become transparent or translucent when dispersed in a vehicle (binder, softener, etc.). Each transparent colorant is used in an amount of 1 to 20 parts (by weight, hereinafter the same), more preferably 5 to 15 parts, based on the total amount of the thermal transfer ink layer. Since the pigments or dyes used as the colorants are transparent or semi-transparent, when they are used to reproduce full colors, vivid and very desirable results can be obtained. However, when reproducing multiple single colors instead of full color, color mixing occurs at the intersections of each color.
I can't get a clear image. For example, if there are several types of characteristic values in a diagram, each color may be reproduced independently in multiple colors, or if a copy is used as a manuscript, and the background of the manuscript contains line drawings, etc. There is a problem in that color mixture occurs at the intersections, and the resulting copy does not produce a clear image. [Problems to be Solved by the Invention] The present invention solves the above-mentioned drawbacks of color thermal transfer recording media, and provides a thermal transfer recording medium that can reproduce the original hue of the thermal transfer medium on any transfer paper. The purpose is to provide. [Means and effects for solving the problems] The object of the present invention can be achieved by setting the opacity of the recording medium measured according to JISP-8123 to 70% or more. In the present invention, the opacity is increased by adding an opaque pigment to a chromatic transparent colorant or an opaque colorant to obtain a predetermined opacity. By setting the opacity to 70% or more, when hues are superimposed, they are not influenced by the previous hue, and color mixing does not occur. Opaque pigments include titanium dioxide, zinc oxide,
Examples include, but are not limited to, calcium carbonate, titanium white, and the like. All commonly used colorants can be used, but there are only a few opaque ones, so it is best to use the transparent or translucent colorants described in the prior art section and add opaque pigments to achieve the purpose. I can do it. Examples of the binder include carnauba wax, microcrystalline wax, wood wax,
Appropriately selected from waxes such as beeswax, ceresin wax, paraffin wax, and soft wax,
These binders are used in an amount of 20 to 80 parts based on 100 parts of the total amount of the ink layer. The softener may be appropriately selected from easily heat-meltable substances such as petroleum resins, polyvinyl acetate, polystyrene, styrene-butadiene copolymers, cellulose ethers, cellulose esters, and acrylic resins, or lubricating oils. be done. These softeners are used in an amount of 3 to 25 parts based on 100 parts of the total amount of the ink layer. Furthermore, a heat-resistant layer for the purpose of preventing sticking may be provided on the opposite side of the base material from the heat-sensitive ink layer. Examples of the constituent material of the heat-resistant layer include known silicone resins, epoxy resins, melamine resins, phenol resins, fluororesins, polyimide resins, nitrocellulose, Teflon resins, acrylic resins, and isocyanate resins. Further, in order to prevent excessive gloss of the image transferred between the substrate and the heat-sensitive ink layer, a matte layer may be provided using the same material as the heat-resistant layer. The present invention is not limited to the above examples. [Example] Hereinafter, the thermal transfer recording medium of the present invention will be explained with reference to Examples and Comparative Examples. Examples 1 to 3 and Comparative Examples 1 to 2 A polyester film with a thickness of 6μ is used as a base material,
Five types of heat-sensitive transfer ink layers having the compositions shown in Table 1 (numbers indicate parts by weight) were coated with a gravure coater at a coating weight of 4.5 g/m 2 to obtain a heat transfer recording medium. Images were formed on these recording media using the Xerox Telecopier 245 and the image quality was evaluated. Table 2 shows the results.
