The paper substrate is coated with MT polyethylene resin, and the polyethylene layer on both sides of the emulsion coating is coated with titanium dioxide, and in fact, it is a method that contains T-containing materials such as Group II and fluorescent brighteners.

There is a tendency for stains (hereinafter referred to as gripp stains) to occur, and to make matters worse, these gripp stains tend to grow larger and larger as the extrusion time passes.

This is because streak-like unevenness due to non-uniformity occurs, and dirt adheres to the film and the material is finished. As a result, the image quality of the manufactured polio V-fin tree cover is seriously impaired, and because of its excellent image quality, it is unsuitable as a photographic support and has no commercial value. .

がわかった。Akira Shigeki et al. have conducted various studies on this OG lip stain OIi, and found that there are major problems with titanium dioxide contained in polyolefin tree layer substances.9.Titanium dioxide When the O content is 0 and the O content of titanium dioxide in the polyolefin tree is low, the occurrence of gripp stains is small, but the hiding power is small and it cannot be used as a photographic support. It was found that when the content is high, the hiding power is sufficient, but the occurrence of greasy stains is significant.

A 4-hour diet that is resistant to photodegradation provides superior quality that is comparable. Moreover, compared to surface gold, it uses two-year-old titanium that is made of titanium dioxide and has no surface treatment.
It is possible to obtain a photographic support with high Kameyaba force.

ことが判明している。From the details of previous research by the present inventors, it has been found that when high-grade polyethylene is contained in a polyolefin tree fiber composition, or when the content of titanium dioxide is increased in a polyolefin tree composition, greasy stains occur. It has been found that the disease occurs more frequently and becomes a bird.

Since the iK1 true emulsion layer tube is provided, the structure of the front and back surfaces of the photographic support is significantly different, resulting in curling. To correct this, it is common practice in the industry to incorporate high-density polyethylene resin into the tin dioxide-containing resin layer and the back resin layer to create a curl balance.

いる。Although it is known that the inclusion of high-II polyethylene resin M in a polyolefin tree fiber composition promotes the occurrence of grip stains, its use is unavoidable from a quality standpoint. is the reality. In addition, increasing the content of titanium dioxide in the resin layer of a photographic support improves sharpness, so it is appropriate to increase the amount of titanium dioxide in photographic supports that require high quality. However, as the content of titanium dioxide increases, the occurrence of smearing and gripping stains increases significantly, and it becomes impossible to produce a 4-hour product. Therefore, in @autumn, the amount of titanium dioxide society is at a minimum @l! A photographic support with a high titanium dioxide content of 90% is produced without having to be manufactured in a suppressed form and of high quality.

It can be seen that surface-treated titanium dioxide is not suitable for practical use because of the generation of grip stains. On the other hand, titanium dioxide, dimethylsiloxane, and dimethylphenylsilokinane without surface treatment did not cause grip stains.
