Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a photographic film package, and more particularly to a silver halogen roll film package suitable for a pseudo-zoom camera.

(Prior Art) In recent years, silver halide color photographic light-sensitive materials for photography (including color negative and color reversal light-sensitive materials) have been developed.

Improvements in the graininess, sharpness, and color reproduction of color negatives (collectively referred to as color negatives), combined with the spread of cameras equipped with zoom lenses or bifocal lenses, have made it possible to obtain a greater variety of high-quality photographs. It is becoming more and more common.

However, for cameras equipped with a zoom lens or bifocal lens, increasing the focal length on the telephoto end will make the camera larger and make it less portable (on the other hand, if you prioritize making the camera smaller, you will not be able to achieve a sufficient telephoto effect). It had the disadvantage that it was not a camera.

As a means to solve this problem, U.S. Patent No. 3.490
．． No. 844, No. 4,583,831 and No. 4,65
0,304, etc., a so-called pseudo-zoom method has been proposed, paying attention to recent advances in color negative film. The pseudo-zoom method uses information about the focal length of the lens that was input in some way during the shooting stage to be detected during the printing stage, and then stretches the negative film to create a telephoto effect. be.

This pseudo-zoom method is based on the premise of a silver halide color negative roll film housed in a 135 format cartridge, which is currently the mainstream.

(Problem to be Solved by the Invention) However, if the above-mentioned pseudo-zoom method is implemented using the currently mainstream 135 format color negative roll film, the photographic image quality, especially the lack of sharpness, results in extremely poor-looking prints. It turned out to be quality. This is considered to be due to the following two factors.

The first factor is that pseudo-zooming differs from simply large-sized prints in that it corresponds to cutting out part of a large-sized print to make a smaller-sized print, and the enlarged image is evaluated at a normal viewing distance. However, the sharpness of negative film is designed to optimize the image quality when expanded from the conventional 135 format screen size to a service size (8 cm x 12 cm).

For example, to improve the sharpness of color negative films, development inhibitor-releasing couplers (so-called DIR couplers) are generally used.
is known to have an effect, for example, RD-17
Patents listed in Sections 643■ to F, JP-A-57-151
No. 944, No. 57-154234, No. 60-1842
No. 48, No. 60-37346, U.S. Patent No. 42489
It is described in No. 62, etc. The improvement in sharpness provided by the DI'R coupler takes advantage of the adjacency effect during development and is therefore dependent on the enlargement magnification. Current color negative films are designed to provide the best image quality when stretched from a 135-format screen size to a service size print (8 cm x 12 marks), and DIR couplers are also selected with this in mind.

The second factor is that telephoto photo prints using pseudo zoom,
As mentioned above, it is compatible with prints made from small format films such as 110 format, but unlike 110 cameras, there is no pressure plate to ensure the flatness of the film, and there is no light-shielding paper that impairs the flatness of the film. Although it was thought that the sharpness would not deteriorate due to the presence of the film on the back side of the film, in reality, there are factors that deteriorate the sharpness as described below.

In other words, the body of the cartridge for 135 format is cylindrical as shown in Figure 1, and the length of the film exit part (port part) varies, and the part of the telescope that protrudes from the port part makes it difficult to enter the camera. Since the attitude is determined, when the cartridge is loaded into the camera, the attitude of the cartridge within the camera cannot be controlled univocally.

For this reason, in a combination of a 135 cartridge and a camera that has a function to detect film sensitivity using a general X code, the film exit of the cartridge and the plane containing the camera's exposure stage are always It is not possible to maintain the same plane substantially, and furthermore, once loaded, photographs are taken while remaining in a non-flat state. If the film exit of the cartridge is far off the surface of the exposure stage of the camera, the film, especially near the film exit, will be set in the camera in a sagging state. It has been found that when a warped film is fed into the exposure stage of a camera, changes in the curl state of the film at the exposure stage are accelerated when the humidity changes, and the flatness of the film is significantly deteriorated. Particularly in a pseudo-zoom print system, where the enlargement magnification is large, the above-mentioned poor film flatness becomes a serious defect. Therefore, it has been found that establishing a technique for stably maintaining film flatness on the exposure stage of a camera is a new challenge for improving the image quality of prints obtained with a pseudo-zoom printing system.

In view of the above, a first object of the present invention is to provide a photographic film package containing a silver halide photographic light-sensitive material and a cartridge containing the same, which allows prints with excellent sharpness to be obtained.

A second object of the present invention is to provide a package containing a silver halide color negative photographic material suitable for a pseudo-zoom printing system.

(Means for solving the problem) These objectives are as follows: ■) A spool shaft (1
4) Film outlet (13) for loading and unloading photographic film
), and has a cartridge (1) that rotatably stores the spool around its axis, when the cartridge is loaded into a camera, the film outlet is connected to the exposure light inside the camera. Stage (12)
(A), and the photographic film loading/unloading direction (B) is within the camera's photographic film winding direction (
C), the photographic film contains at least one development inhibitor-releasing compound, the total thickness of the photosensitive layer is 24 μm or less, and the photosensitive layer The total oil droplet volume of 5. A photographic film package characterized in that it has an Oal/rn' or less.

2) It has been found that the following can be achieved by the photographic film package according to item 1), wherein the photographic film contains at least one kind of polymer coupler.

In other words, by improving the processing precision of the film exit part and controlling the cartridge in the set position within the camera,
By improving the flatness of the film and the sharpness in the spatial frequency region that is most necessary for the film when implementing the pseudo-zoom method, the sharpness mainly in the low frequency side is improved by the development effect, and by reducing light scattering. The improvement is based on the idea of improving sharpness mainly on the high frequency side, and by combining these two technologies, when visually observing a print that has undergone the pseudo zoom method, the sharpness can be dramatically improved. was confirmed to be possible.

The photographic film package of the present invention will be described in detail below.

The cartridge in the photographic film package of the present invention includes:
As schematically shown in Figure 1, when loaded into the camera, the film exit (3) is connected to the camera's exposure stage (12
), and has means for controlling the posture so that the photographic film loading/unloading direction (B) is parallel to the photographic film winding direction (C) within the camera.

By providing the above attitude control means, the cartridge is loaded in the camera, and the photographic film (2) is passed from the film outlet of the cartridge to the film winding means in the camera on the other side through the exposure stage. When loaded, the flatness of the photographic film and the flatness of the film near the film exit of the cartridge can be maintained.

``The film exit (3) is connected to the camera's exposure stage (12).
"Keeping the photographic film (2) within the plane (A) containing the film" means that the photographic film (2) is not bent in the vicinity of the film exit of the cartridge. Further, the film outlet (3) and the exposure stage (12) of the camera do not necessarily have to be in contact with each other.

In order for the cartridge to be uniquely posture-controlled so as to maintain the above-mentioned flatness when loaded into the camera, the cartridge must basically rotate around its spool shaft (4) in the cartridge loading chamber (13) inside the camera. All you have to do is set it so that you can't exercise.

Specifically, it is preferable to provide means for engaging the camera so that the cartridge maintains the above-mentioned planar shape. Further, in order to obtain better engagement, it is preferable to improve the accuracy of the dimensions of the cartridge's outer shape, and in particular, it is preferable to improve the accuracy of the dimensions of the port portion.

Specific means for setting the attitude control of the cartridge as described above, in other words, means for engaging the cartridge and the camera, include, for example, the following.

First, the shape of the plane perpendicular to the cartridge spool axis (
(excluding the film exit section) can be non-circular to engage the cartridge loading chamber of the camera.

The surface perpendicular to the spool axis that should be non-circular may be either the body (cross section) or side edge (end surface) of the cartridge, but it may be only the side edge or both the body and side edge. It is preferable that

As an example of a non-circular side edge, it is also possible to control the attitude of the cartridge within the camera by making the cross-sectional area (S2) of the side edge larger than the cross-sectional area (S1) of the body of the cartridge. Cross-sectional area of the side edge (S
If 2) is too large, it is not preferable for miniaturization of the camera, so the ratio S2/S is generally 1.2 or less, preferably 1°1 or less, and particularly preferably 1.05 or less.

Specifically, as shown in Figures 5-1 and 5-2,
Mention may be made of a cartridge (1) consisting of a side edge with a non-circular part (21) and a body part (22) with a non-circular cross-section. The non-circular part (21) and preferably the body part (22) are arranged in the cartridge loading chamber (1) of the camera.
It is preferable that springs (32, 33) provided at 3) engage the camera to control its attitude.

An example of a non-circular body is when at least one side of the cartridge body is flat, as shown in FIG. The above-mentioned planar shape may mean that the side surface of the cartridge has sufficient planarity to perform the posture control according to the present invention, and may have some degree of curvedness.

It is also preferred that the flat surface of such a cartridge coincide with and substantially contact a particular surface of a cartridge loading chamber within the camera. Here, "substantially contact" means contact sufficient to perform posture control according to the present invention, and does not necessarily mean complete contact.

A second means for engaging the cartridge and the camera is to provide the cartridge and the camera with at least one joint portion that can be held in a cartridge loading chamber within the camera so that the attitude of the cartridge can be controlled according to the present invention.

The installation location, number and shape of such joint parts may be arbitrary as long as the attitude control of the cartridge according to the present invention can be achieved.

For example, the joining means may include a method in which a so-called protrusion and a recess that fits into the protrusion are provided on the camera and the cartridge, respectively.

For example, as shown in Figure 3, the side edge (6) of the cartridge body can be provided with a convex protrusion (8) for engaging a recess provided in the cartridge loading chamber of the camera. Preferably, such engagement means are provided on both end faces of the cartridge.

Alternatively, as shown in FIG. 4, a linear protrusion (9) is provided on the side surface (5) of the cartridge body, and engages with a linear recess that fits into the protrusion provided in the cartridge loading chamber of the camera. can be combined.

Also, as shown in Figure S, a protrusion (27) can be provided at the film outlet of the cartridge to engage with a recess (26) provided in the exposure stage of the camera. Such a protrusion may be provided anywhere on the film outlet (3), for example, it may be provided linearly along the film outlet, or it may be provided at one location in the center of the film outlet.

In the above, a protrusion may be provided on the camera side, and a recess that fits into the protrusion may be provided on the cartridge. Further, the projection and the depression may have a fitting relationship sufficient to achieve posture control according to the present invention.

As a further joining means, there is a method in which both the camera and the cartridge are provided with at least one set of projections, and the cartridge is held in the cartridge loading chamber in the camera by joining the projections. .

For example, as shown in Fig. 5-1 and Fig. 5-2, the cartridge is connected by the protrusion (23) on the cartridge and the protrusion (34) inside the camera, and the protrusion (24) on the cartridge and the protrusion (35) inside the camera, respectively. It can be held in the cartridge loading chamber within the camera. Either one of the above-mentioned holding means may be used depending on the case. Further, the holding means by the protrusion (24) on the cartridge and the protrusion (35) in the camera may be provided on both end faces of the cartridge.

As for the engagement means for controlling the posture of the cartridge according to the present invention, it is sufficient to have any one of the above engagement means, but two or more may be used in combination (Figs. 3, 4, and 4). (See Figure 5-L).

Furthermore, in order to better set the above-mentioned posture control, it is preferable that the dimensional accuracy of the outer shape of the cartridge is ±0.5- or less, and ±0. It is more preferable to set it to 3 mm or less.

In addition, in order to set posture control even better, the dimensional accuracy of the length of the port part has been adjusted to ±0. It is preferable to set it as 3mm or less, and ±0. It is more preferably 2 mm or less, particularly preferably ±0.1 stroke or less.

In order to maintain the flatness of the film, it is preferable to make the port portion so that no light-shielding telescope protrudes or to use no telescope.

In order to ensure this accuracy, it is preferable to mold the cartridge using resin.

Non-photosensitive fine grain silver halide is a silver halide fine grain that is not exposed to light during imagewise exposure to obtain a dye image and is not substantially developed during the development process, and is preferably not fogged in advance. .

The fine-grain silver halide has a silver bromide content of 0 to 100 mol %, and may contain silver chloride and/or silver iodide if necessary. Preferably, it contains 0.5 to 10 mol% of silver iodide.

The fine grain silver halide has an average grain size (average diameter equivalent to a projected area of 9 yen) of 0. OI ~ 00.5 μm is preferable, 0
．． 02 to 0.2 μm is more preferable.

Fine-grain silver halide can be prepared in the same manner as ordinary photosensitive silver halide. In this case, the surface of the silver halide grains does not need to be optically sensitized, nor is spectral sensitization necessary. However, prior to adding this to the coating solution, it is preferable to add a known stabilizer such as a triazole-based, azaindene-based, benzothiazolium-based, or mercapto-based compound, or a zinc compound.

Known photographic additives that can be used in the present invention are also described in the above two Research Disclosures, and the relevant descriptions are shown in the table below.
