Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a silver halide photographic material that is housed in a cartridge that can be easily loaded into a camera and allows for viewing high-quality photographs easily and inexpensively. With the spread of color photographic materials, there is a growing demand for anyone to be able to easily take high quality color photographs.

With the remarkable progress in camera light control mechanisms, loading color photographic film into the camera has surprisingly become a difficult point for many people during their professional photography work.

"It's Utsurun) iiJ" and "Utsurun desu Flashco (
For this reason, Fuji Photo Film Products (product name) became popular. However, those who want high-quality color photos may not be satisfied with this camera, and the price per frame is relatively high compared to other compact cameras.

Conventionally, color photographic film stored in IIO size cartridges and similar color 4X film in /CO2 size have been sold (ANSI/ASCPH1,4tO
-/Yrll'PANSI/ASCPH1,J! r-/
? (according to standards such as 14). All of these had advantages over conventional cameras, such as being easy to load into the camera, having excellent film transportability, and allowing the film to be replaced even before shooting was completed. However, the size of the photographic screen is small, the quality of the enlarged prints is not sufficient, and it is difficult to stably align the photosensitive surface of the photographic film with the image forming surface, which tends to result in blurred photographs. 73!
Nowadays, sizes have become more widespread, and the aspect ratio of the shooting screen is also unfavorable.

It's hard to get good photos. In addition, if a light-shielding paper is not used, there are problems such as the photographic film is likely to be covered, and it is also easy to cause scratches and pressure sensitivity. The first object of the present invention is to make the shooting screen size larger and wider than /10, /26 size, and to make the ratio of vertical and horizontal sides appropriate, and to take high-quality photographs stored in an inexpensive cartridge. An object of the present invention is to provide a silver halide photographic light-sensitive material. D. It can be easily attached to the camera, it can be easily attached and detached after shooting, and preferably the camera can be reused, and the camera has a built-in cartridge containing the color photographic film in advance, and is preferably packaged with a halogen film.

What are the advantages and disadvantages of the silver halide photographic material of the present invention using the cartridge of the present invention? /% silver halide by improving the composition of the photographic light-sensitive material. The first disadvantage of using a cartridge is that the effective screen area exposed to light in the exposure aperture is large, and by changing the shape, it is difficult to maintain the flatness of the photosensitive surface, making it difficult to align the photosensitive surface with the imaging surface.

Especially normally, /J! In the case of a camera using a cassette, the photosensitive surface is moved to the image forming surface by the tension of the film between the sprocket, the nut in the cassette and the winding and shaft in the camera, and the pressure from the film support surface. It can be adjusted to Conventional types of /10 size, /, and 26 size cartridges do not have this innovation. Furthermore, when a photographic material is conveyed in a cartridge along with light-shielding paper, it is particularly difficult to align the photosensitive surface with the image forming surface. The first problem is that it is easy to cover the cartridge when you remove it from the camera. For this purpose, light-shielding paper is used. The defect of using light-shielding paper increases the production cost of the cartridge and also impedes the miniaturization of the cartridge. Furthermore, the light-shielding paper must be disposed of as waste after the development process.

The first disadvantage of using a cartridge is that the film support surface of the bridge part of the cartridge is a surface that can be pressurized, and a pressure plate is provided in the frame of the exposure aperture during photography, preferably a mechanism that applies pressure only during photography. Although it is possible to create a gap between the cartridge and the camera body, it is not enough.

In the present invention, the use of silver halide used in silver halide photographic light-sensitive materialsff3. OP or l.

or, preferably J, OP or 1.5? , especially 7.0
? The sharpness of the image can be improved as follows. To reduce the total thickness of the photosensitive layer without reducing the amount of silver halide used and at the same time, without lowering the ratio of the amount of binder used to the amount of silver halide used, e.g.
1, preferably -20 μm to 70 μm1, and particularly preferably less than /J'μm, thereby improving the sharpness of the image.

One method of improving the sharpness of an image is to use a dye to prevent irradiation or halation, but this method is disadvantageous in that it lowers the effective sensitivity.

The reason why the method of reducing the amount of silver halide used according to the present invention is particularly effective for the purpose of the present invention is that the degree of blurring of images due to fluctuations in the flatness of the exposure aperture of the cartridge according to the present invention is It appears to rely primarily on the scattering of light upon exposure by silver halide grains in the silver halide emulsion layer of the material. Therefore, it is preferable to allocate the total amount of silver halide to be used in each silver halide emulsion layer unit, such that a large amount is used in relatively high sensitivity silver halide emulsion layers and also in low sensitivity emulsion layers. The total amount of silver halide used in the highest sensitivity emulsion layer in each silver halide emulsion layer unit is o, i to 1M7m,
Preferably 0. / or 4! f/m. This condition is particularly preferred for silver halide color photographic emulsions having a photosensitivity of 15 OJ or more.

On the other hand, the total amount of silver halide used in the low-speed emulsion layer is! It is less than /l/m2, preferably φ to iy7m2.

The second disadvantage of using a cartridge is that the photographic film exposed to the exposure aperture can be protected by providing a light-shielding member at or near the port of the film roll chamber and winding chamber of the cartridge of the present invention or the frame of the exposure aperture. You can avoid wearing it by removing it. As the light-shielding member, it is preferable to use a resilient black member such as terempu, foamed plastic, a soft plastic piece, or a planutek sheet, as described in, for example, Japanese Utility Model Application Publication No. 1988-Noko OAPR.

It is preferable to use a dispersion, a micellar dispersion of the dye, etc., in which the dye or pigment is dispersed in a binder that is removed or dissolved in the development process on the back side of the support. For example, % Gansho 4! -2! ?
