る。Thermal transfer type printers combine a receiving sheet such as normal high-quality paper with an ink sheet consisting of a thin substrate such as a film and a layer of thermally fused ink, and transfer the image from a thermal head in response to an image signal. Due to the force of the heat, the thermally molten ink is transferred to the receiving sheet only in the necessary areas, forming the entire image.

In the case of a color printer, all images of different colors such as yellow, magenta, cyan, and black are transferred and combined to obtain a color image. By using area gradation and degree gradation, full color images can be obtained by thermal transfer recording.

転写画像の鮮明度が改善されることが知られている。For receiving sheets for thermal transfer printers such as those using the area gradation method, in order to obtain good transferred images, a smoothing process is performed using ordinary paper with a Beck smoothness of about 10 to 50 seconds, a super calender, etc. However, if it is 100 seconds or more,
It is known that the clarity of transferred images is improved.

の改善が倚られている。Furthermore, in order to improve the transfer characteristics of thermal transfer printers, a proposal has been made to obtain a transferred image with even shading by providing an oil-absorbing pigment on the entire paper base material (1824/1989).
Publication No. 87). This publication lists most of the pigments used in coated printing papers, and claims that a certain degree of improvement in thermal transfer receptivity has been achieved.

In order to cover the entire area, the dither method using the area gradation method requires an additional 16~

高鼾隊度ケ有する画像金得ることは困難であった。Being able to see the entire image with good reproducibility is simply a matter of Beck smoothness being 100.
For high-quality paper of seconds or more, it is a rotation axis. In printers that fully control the amount of bath-melted ink transferred from the thermal head, the uniformity of the ink-receiving ability of the receiving paper has a significant impact on the quality of the image. Even when a heat transfer receptor sheet coated with pigment was used, density unevenness or uncertain transfer of halftone dots was observed, making it difficult to obtain images with good intermediate tones (1') and high chromaticity. .

的とするものである。In view of this current situation, the inventors of the present invention have developed a technology that reproduces the transfer ink without halftone dots and density unevenness, and that can be obtained with a full-color printer, etc., with clear, high-resolution recorded images from low density to high density 1. The object of the present invention is to provide a receiving sheet for thermal transfer recording.

善できること全見出した。The inventors of the present invention have conducted intensive research to improve these drawbacks, and as a result, we have found that the receiving sheet for thermal transfer printers has a calcite crystal system, a spindle shape, and a particle size (major axis).
When neutral paper containing 1 to 70% by weight of light calcium carbonate, preferably 10 to 400 to 40% by weight, based on the pulp, is used as a receiving sheet for a thermal transfer printer. It is possible to improve the reliability of dot reproduction, the reproducibility of density, and the reproducibility of hue and density of overlapping colors in a method that reproduces the entire halftone image of density gradation or blood gradation method. I found out everything that could be done to improve the problems.

粒径とその分布全制御する。Calcium carbonate is the preferred filler for acid-free paper, and calcium carbonate can be broadly divided into heavy carbonate and light (precipitated) calcium carbonate. Liangji calcium carbonate is obtained by dry or wet grinding of naturally occurring limestone. Precipitated calcium carbonate can be obtained by dissolving quicklime in water and blowing carbon dioxide gas into the solution to cause a reaction. The particle size of the filler and its distribution are completely controlled by the grinding conditions of calcium carbonate.

沈降性炭酸カルシウムの結晶系は、カルザイト(六方晶
形)、アラゴナイト(斜方晶形)、バテライト(六方晶
形)の6種類に分けられる。The crystal system of precipitated calcium carbonate is divided into six types: calzite (hexagonal crystal), aragonite (orthorhombic crystal), and vaterite (hexagonal crystal).

カルシウムは、当然粒子形状が不規則である。Of these, vaterite is rarely used industrially because its crystals are unstable. The preferred calcium carbonate used in the present invention is a spindle-shaped calcite crystal type of precipitated calcium carbonate. Calcite-type crystals also include cubic particles. Aragonite is spindle-shaped and elongated (with a large aspect ratio) and columnar. Moreover, the particle shape of heavy calcium carbonate is naturally irregular.

る。重質炭酸カルシウムは粒子形状が不規則で吸油量も
小さいためか、インクの転写が良くない。As a result of a comparative evaluation of these neutral papers filled with calcium carbonate using a thermal transfer printer, the paper filled with spindle-shaped calzite was superior. Although the detailed reason is not clear, it is presumed that the filled filler becomes sloppy, creating an excessive space in the paper layer. Assigonite has thin and small crystals, so the surface is dense and di-ink transfer is poor. Heavy calcium carbonate does not transfer ink well, probably because its particle shape is irregular and its oil absorption is small.

のと推定される。粒子径(長径)が2μm以上の粒子が
50重量%以上であることが好ましい条件である。If the particle size is small, oil absorption is generally large and ink transfer is improved, but if the particle size is too small, the yield during filling becomes poor and it cannot be practically used for paper making. Besides that,
It is estimated that transferability, image quality, etc. will deteriorate if there are many particles with small particle sizes. A preferable condition is that particles having a particle diameter (longer axis) of 2 μm or more account for 50% by weight or more.

It has been found that m1 is preferably 79 or more, and particularly desirably 20 m14/, 9 or more.

できる。In addition to the spindle-shaped calcite-type precipitated calcium carbonate, the pigment to be filled may be hexahedral precipitated calcium carbonate, heavy calcium carbonate, etc., as long as the overall image quality does not deteriorate.
Pigments such as clay, calcined tar, titanium dioxide, aluminum hydroxide, talc, calcium silicate, calcium 4A acid, magnesium silicate, and synthetic amorphous silica can also be used in combination.
