Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cartridge formed by winding and storing a film and a film stored therein.
The present invention relates to a cartridge that can be applied to a double magazine system for large screen size roll films such as M5 roll films, and a film stored therein.

[Conventional Technique #] Conventionally, along with the automation of cameras, a double magazine system having a film supply chamber and a take-up chamber has been widely adopted for film cartridges.

These days, not only one-ten film, but also high-quality 3
5. Adoption of a double magazine system is also being considered for roll film.

However, when such a double magazine type cartridge is adopted for a large screen size roll film such as a 35 mm roll film, ensuring the flatness of the film shooting surface becomes an important issue.

In other words, in the case of a normal roll film without a winding chamber,
Flatness can be maintained by pressing the back cover of the camera, but in the case of a double magazine system, it is impossible to press the film with the back cover of the camera. If no special measures are taken to ensure the flatness of the film surface, a so-called out-of-focus problem will occur due to warping or curling of the film surface, and the out-of-focus image will be accentuated by stretching during printing. There is also the issue of matching the commercial value of prints.

Regarding countermeasures against such out-of-focus, the present applicant previously proposed a plan on July 2, 1986, in order to ensure the flatness of the film shooting surface.
An application for utility model registration (name of the invention: film cartridge) was filed on the 1st.

[Problem to be solved by the invention] However, in the method using a pressure bonding plate as in the previously proposed technique, manufacturing man-hours and costs are required to manufacture a pressure bonding plate having a smooth surface, and the cost of the cartridge itself increases. There are some drawbacks.

Therefore, it is desired to develop a technique that can prevent out-of-focus without increasing costs.

[Object of the Invention] An object of the present invention is to provide a means for preventing out-of-focus during photographing with respect to large screen size roll films such as 35+us roll films, without the complexity and cost increase of cartridge manufacturing.

[Means for Solving the Problems] In order to achieve the above object, the present inventors have conducted intensive studies and have arrived at the present invention.

Specifically, 1 the film cartridge according to the present invention is a double magazine type cartridge having a film supply chamber in which an unexposed film is wound and stored and a film winding chamber in which an exposed film is wound. A silver halide color photographic light-sensitive material having a light-sensitive silver halide emulsion layer for forming a cyan image, a light-sensitive silver halide emulsion layer for forming a magenta image, and a light-sensitive silver halide emulsion layer for forming a yellow image. The screen size of the photosensitive material is 400s+tm" or more, and the thickness including the support and all layers coated on the support is 13
It is characterized by being 0 to ztop■.

Further, the film according to the present invention is a double magazine type cartridge film having a film supply chamber in which unexposed film is wound and stored and a film winding chamber in which exposed film is wound.

The halogen film has a light-sensitive silver halide emulsion layer for forming a cyan image, a light-sensitive silver halide emulsion layer for forming a magenta image, and a light-sensitive silver halide emulsion layer for forming a yellow image on a support. It is a silver oxide color photographic light-sensitive material, and the screen size of the light-sensitive material is 4001" or more, and the thickness including the support and all layers coated on the support is 130 to 2101Ltn. Features.

In the film of the present invention (hereinafter referred to as photosensitive material),

In the present invention, the area of one frame (screen size) of the photosensitive material (negative or positive) is 400 cm or more, for example 3
5■ type, the layer thickness of the present invention is 130 to 2
By setting it to 10, the effect of preventing out-of-focus is more effectively exhibited.

If the layer thickness of the present invention is less than 1301Ls, the effect of preventing out-of-focus cannot be exhibited, and if it exceeds 210Ls, the winding of the film becomes difficult, which is undesirable.As a support, cellulose ester such as triacetate cellulose A film, a polyester film such as a polyethylene terephthalate film, etc. are preferable, and a film in which a thin polyethylene terephthalate film is removably coated on a triacetate cellulose film with an adhesive layer can also be used.

Furthermore, to explain in detail the polyester mentioned here, it is a polyester whose main components are aromatic dibasic acid and glycol, and typical dibasic acids include terephthalic acid, isophthalic acid, and p-β-oxydiethoxybenzoic acid. , diphenylsulfone dicarboxylic acid, diphenoxyethane dicarboxylic acid, adipic acid, sebacic acid, azelaic acid, 5-sodium sulfoisophthalic acid, diphenylene dicarboxylic acid, 2,6-naphthalene dicarboxylic acid, etc. Glycols include ethylene glycol , propylene glycol, butanediol, neobenzene gelicol, 1.4-cyclohexanediol, 1.4-
Examples include cyclohexane dimetatool, 1,4-bisoxyethoxybenzene, bisphenol A, diethylene glycol, polyethylene glycol, and the like. These polyester films can be produced using a known biaxial stretching method, such as that described in JP-A No. 52-54428.

In addition, it is also preferable to use known means for preventing static electricity independently from this. For example, fluorine-based surfactants, various conductive polymers, inorganic oxides, organic antistatic agents, etc. are contained in the undercoat layer. This is a method of forcing people to do so.

These treatments may be performed on only one side of the support or on both sides, and of course, the treatment applied to one side of the support may be applied to the sealing of the other side. It does not matter if the treatment is different from the treatment performed beforehand, and furthermore, two or more different types of treatment may be used together.
