本発明は電子写真用転写紙に関するものであり、特に写
真や印刷並の画質を再現するモノクロームおよびカラー
電子写真複写機において、高画質コピーを得るのに好適
な電子写真用転写紙に関するものである。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to electrophotographic transfer paper, and is particularly useful for high-quality copies in monochrome and color electrophotographic copying machines that reproduce image quality comparable to photographs and printing. The present invention relates to an electrophotographic transfer paper suitable for obtaining.

においては、アート紙、コート紙等の塗工紙が使用され
ている。これは塗工紙の表面が平滑なために、印刷時に
インキ皮膜との接触が良く、画像が忠実に再現されるこ
と、画像の光沢が高く、色再現が良いことなどによる。[Prior Art] Coated papers such as art paper and coated paper are used in elaborate printing and multicolor printing, where planar offset printing is the mainstream. This is because the coated paper has a smooth surface, which allows for good contact with the ink film during printing, resulting in faithful reproduction of images, high gloss, and good color reproduction.
塗工紙の電子写真適性については、塚谷等の検討がある

刷用塗工紙を電子写真に用いても画質上の利点はなく、
はとんど使用されていない。Regarding the suitability of coated paper for electrophotography, there is a study by Tsukatani et al. They argue that coated paper is physically smooth and adheres uniformly to the photoreceptor, so theoretically it should be possible to obtain a clean toner transfer image, but they have not actually applied it to existing equipment. In some cases, the image becomes rough (Tsukatani, Ota:
Non-impact printer paper, paper pulp technology times,
27° No. 4 (1984) 31-36>. In fact, there is no advantage in image quality when using coated printing paper for electrophotography.

ものである。Studies conducted by the present inventors have revealed that smooth coated paper for printing causes double feeding and paper jams during paper feeding in electrophotographic copying machines. It has been confirmed that this problem occurs frequently regardless of the paper feeding method, such as the feed roll/corner snapper type or the feed roll/retard type. It has been found that the cause of this is that the coefficient of static friction between coated printing papers in a stacked state is much larger than that of plain paper. This is because the coated paper is smooth, so the contact between the papers is too good, and
This is due to the characteristics of the paint binder and pigment present on the surface.

が良いことが確認されている。In these technical aspects, if the problems of coated paper for printing in electrophotography can be solved, the use of smooth coated paper is considered to be advantageous in terms of image quality. In addition, it has been confirmed that smooth coated paper is better for fixing images with emphasis on gloss and color reproduction, as well as for electrophotography, as well as for printing.

用の塗料にも配合されている。This transfer paper is made by coating the base paper with a paint mainly composed of high electrical resistance resin in order to improve the image disturbance caused by the low electrical resistance of the magnetic component developer. The coating amount is small in order to resemble that of , and the surface is low and smooth, making it unsuitable for the above-mentioned high image quality applications. The same pigments used in the coating for coated printing paper are also included in the coating for this transfer paper.

I can not use it.

グロスムラが大きくなり好ましくない。The present inventors evaluated the color deterioration of color toner for electrophotography using commercially available coated printing paper, high-quality paper, and prototype coated paper.As with printing, coated paper was superior to high-quality paper. It was confirmed that there was little color deterioration. For these papers, use the GARDNER gloss meter GARDNER GLO.
Measured using 3SGARDI. In addition, the center line average roughness was measured using a universal surface profile measuring device 5u manufactured by Kosaka Institute Co., Ltd.
JISB using rfcorder 5E-3G
According to the method of O601, the measurement was performed with a cutoff value of 0.8 and a measurement length of 81rIIr4, and the relationship between loss and center line average roughness as shown in FIG. 1 was obtained. From this result, for cloth, the boundary between coated paper and high-quality paper with less color deterioration is 10
%, matte-finish coated paper and high-quality paper exist in this area, making it difficult to distinguish between the two, whereas for the center line average roughness, if the boundary value is 2μ, it is possible to clearly distinguish between the two. There was found. Furthermore, in order to develop color toner sufficiently, the toner needs to be sufficiently melted during fixing, and the cross becomes high, so if the cross of the paper is too low, uneven gloss in the copy will increase, which is not preferable.
この点からは紙表面の中心線平均粗さはクロスが20%
以上となる1、5μm以下が望ましい。From this point, the center line average roughness of the paper surface is 20% for cloth.
The thickness is preferably 1.5 μm or less.

付着性の少ない顔料と接着剤を主体とし、必要に応じて
付着防止剤を配合した塗料を塗工して表面を平滑化し、
紙間の静摩擦係数の標準偏差が0.05以下になるよう
に調整して得られる。The electrophotographic transfer paper of the present invention is made by coating at least one side of the base paper with a paint mainly containing pigments and adhesives with low adhesion, and optionally containing an anti-adhesion agent to smooth the surface.
It is obtained by adjusting the standard deviation of the coefficient of static friction between papers to be 0.05 or less.

等が望ましい。The pigment, which is the main component of the paint, has an average particle size of 1.5 because the coated surface is smoothed using a super calender etc. after coating.
Fine particles of 1.0 μm or less, preferably 1.0 μm or less, are suitable, such as heavy calcium carbonate, light calcium carbonate, kaolin clay, sericite, gicrite, calcined clay, aluminum hydroxide, lithopone, zinc oxide, Examples include titanium dioxide, barium 'fiM acid, silica, and urea resin pigments. Particularly desirable are heavy and light calcium carbonate, calcined clay, etc. as small pigments that are easy to smooth and adhere.

もよい。It may not be possible to reduce the standard deviation of the coefficient of friction between papers in a stacked state to 0.05 or less by simply blending the pigment and adhesive. In this case, the improvement measures are to add lubricating chemicals to the coating layer to make it slippery, or to add a small amount of coarse particle pigment within the range that does not reduce the image glossiness, thereby creating an air gap between the sheets. This can be achieved by intervening. Alternatively, by changing the average particle size of the pigment used on the recording surface and the non-recording surface of the coated paper,
A fine particle pigment may be used on the front surface to ensure image glossiness, and a coarse particle pigment may be used on the back surface to provide an air layer.

これらの粗粒子顔料を非記録面に配合する場合には顔料

0%にとどめる必要がある。When blending these coarse particle pigments on the non-recording surface, the entire amount of the pigment may be coarse particle pigments, but when blending on the recording surface, the amount must be adjusted to an extent that does not reduce the image quality and glossiness, that is, 1 to 1.
It is necessary to keep it at 0%.

必要がある。The smoothing process is performed using JISBO to obtain sufficient image glossiness.
The center line average roughness of the surface according to 601 is 2゜0LITrL
Hereinafter, it is necessary to adjust the thickness to preferably 1.5 μm or less.
この必要な中心線平均粗さを得るためには平滑化処理工
程だけでコントロールできるものではなく、顔料の粒径
、配合比、塗工量、塗布方法をも考慮する必要がある。In order to obtain the required center line average roughness, it is not possible to control it only by the smoothing process, but it is also necessary to consider the pigment particle size, blending ratio, coating amount, and coating method.

However, in order to provide suitability for electrophotographic copying machines such as runnability and curling properties, the blending, preparation, and manufacturing conditions of the raw materials must be adjusted according to known methods.

The saturation C was determined by the method described above. Further, the halftone dot area ratio of the same halftone dot was measured, and the relational expression between the saturation C and the halftone dot area ratio was determined by the least squares method. Using this relational expression, the saturation C when the dot area ratio is 0.4 was calculated and used as a highlight chroma.

In order to reduce the number of times per 1,000 sheets to 5 times or less, the standard deviation of the coefficient of static friction between stacked sheets should be 0.05 or less, and to reduce running trouble to almost zero, the standard deviation should be 0.02 or less. It is clear that there is a need.
