Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic film package in which a silver halide light-sensitive material is housed in a cartridge, and more particularly to a photographic film package with improved delivery of photographic film and loading into a camera.

[0002]

2. Description of the Related Art A conventional photographic film cartridge packaging body is manufactured and sold with the leading end of the photographic film slightly protruding from the cartridge, and it is necessary to pull out the photographic film a little further to load it into the camera. Alternatively, there is also an automatic loading camera called an automatic loading camera. However, there were mistakes that the film was improperly pulled out due to imperfect loading into the camera and forced to start over, light leakage from the film entrance and exit of the film cartridge.

In order to improve these, a spool around which a photographic film is wound is freely rotatably housed inside the cartridge body, and the spool is driven to rotate, so that the tip of the photographic film is moved from the cartridge outlet to the outside of the cartridge body. A photographic film patrone to be sent out has been proposed in U.S. Pat. Nos. 4,832,275 and 4,834,306. According to this, the user can load the photographic film on the camera without touching the photographic film itself, which has the advantage of eliminating human error.

According to the proposal, the spool of the cartridge rotates when the camera is driven to send the leading edge of the photographic film out of the cartridge main body through the cartridge outlet, and passes through the aperture of the camera to wind it around the winding shaft. By the way, photographic film requires film propulsion torque. If the torque is insufficient, there is a problem that jamming is caused in the cartridge or the camera.

Proposals for increasing the rigidity of the support of the photographic film and adjusting the coefficient of friction with the inner wall of the cartridge have been known, but the former causes inconvenience in handling at the developing station, and the latter causes There is a limit to improvement and it is insufficient.

Prior to coating, the support may be subjected to corona discharge treatment, plasma treatment, undercoating treatment, heat treatment, dust removal treatment, metal vapor deposition treatment, and alkali treatment. Regarding these supports, for example, West German Patent No. 3,338,854A, JP-A-5959
-116926, U.S. Pat. No. 4,388,368, Yukio Mitsuishi, "Fiber and Industry", Volume 31, p50-55, 1975.

In the present invention, magnetic particles may be contained in the support.

In this case, it is preferable to concentrate on the side of the support opposite to the side on which the photographic constituent layers are coated. As a method of concentrating on one surface side of the support, after casting a dope containing a support polymer and magnetic particles, the magnetic particles are concentrated on one surface side of the support by gravity, magnetic force, etc. As shown in JP-B-30-986 and WO91 / 11750, there is a method of simultaneously casting a dope containing magnetic particles and a dope not containing magnetic particles to concentrate them on one side of the support, but the latter is faster. It is preferable because it can be produced in.

In the present invention, the triacetate cellulose ester dope containing magnetic particles and the cellulose triacetate ester dope not containing magnetic particles can be simultaneously cast on a drum or a belt and dried to form a support.
Two casting ports are provided on the endless belt, the cellulose acetate triacetate dope is cast first, and then the cellulose acetate triacetate dope containing magnetic particles is further cast and dried,
It is also possible to form the support of the present invention.

The thickness of the support is 50 to 150 μm, preferably 60 to 130 μm, particularly preferably 70 to 120 μm.
If the thickness is less than this, the accuracy of writing and reading by the magnetic head is reduced with respect to the high-speed coating speed of the silver halide photosensitive material, which is not preferable. On the other hand, if it is thicker than this, the suitability for exposure / developing equipment as a silver halide photosensitive material is deteriorated.

In the support usable in the present invention, the thickness of the layer in which the magnetic particles are present is 2 μm or less, preferably 1.5 μm.
It is particularly preferably 1 μm or less and 0.1 μm or more. The coating amount of magnetic particles is 10 to 1000 mg / m ² , preferably 15 to 300 m

No. 2-93641, No. 2-181748, No. 2-214852, and Japanese Patent Application No. 2-291135, the dispersion stability of magnetic particles is improved by using polyethylene terephthalate having a high water content. Improved and preferable.

It is preferable to add a small amount of a known dye or pigment to the support to prevent halation, irradiation and light piping.

By adding an inorganic or organic matting agent to the dope containing the magnetic particles, or by matting the surface after forming the magnetic layer, the surface roughness is set to a certain region. The efficiency of writing and reading by the head can be improved.

By adjusting the viscosity balance, changing the solvent composition, adjusting the surface tension, and changing the plasticizer content of the dope containing magnetic particles and the dope not containing magnetic particles, Physical properties can be adjusted.

After the support is formed, the process can be simplified by applying an undercoat layer or a backing layer online.

The photographic constituent layers in the present invention are a "photosensitive layer" which contains a silver halide photographic emulsion and is exposed to light to form an image by a developing process, and a photosensitive layer which is around the photosensitive layer. It is composed of a "non-photosensitive layer" which plays a role of protecting, separating and supporting.
