Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide color photographic light-sensitive material, and more particularly to a silver halide color photographic light-sensitive material which is excellent in pressure characteristics and has less scratch defects and is stored in a roll form. And the photographing unit.

[0002]

2. Description of the Related Art With the miniaturization of photographing cameras, the roll diameter of roll-shaped silver halide photosensitive material has come to impose restrictions on camera design. In 1982, Eastman Kodak Company announced a so-called disk camera system using a disk-shaped photographic film to solve this problem. However, when a disk-shaped photographic film is used, it has drawbacks such as a limited screen size and a limited number of images to be taken, and therefore, in recent years, a roll-shaped film has begun to be reviewed again.

Japanese Unexamined Patent Publication (Kokai) No. 1-224750 discloses that a roll-shaped film having a small size and a light weight can be provided by setting the thickness of the support to 25 to 125 μm. Further, Japanese Patent Application Laid-Open No. 1-291248 discloses a technique of eliminating the curl, which is a drawback of a roll-shaped film, by using a polyester film having a high water content.

While research on miniaturization of the roll-shaped film has progressed in this way, when the film stored in the roll-shape is pulled out along with photographing, the front surface and the back surface of the film are rubbed against each other, or the film and the cartridge or the camera. Due to the rubbing with each other, there were new problems that a scratch defect occurred or pressure desensitization occurred when rolled.

[0005]

The film contained in each shooting unit was exposed to light and wound up on a patrone. Thereafter, the film taken out from the cartridge was subjected to the same development processing as in Example 1,
A scratch defect (linear color development) that occurred on the film was confirmed. The results are shown in Table-3.

[0108]

[Table 7]

According to the present invention, it is understood that the scratches are unlikely to occur.

[0110]

According to the present invention, it is possible to obtain a silver halide color photographic light-sensitive material and a photographing unit which are excellent in pressure characteristics and in which generation of scratches is suppressed and which are accommodated in a small roll shape.
