Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a silver halide photographic material.

More specifically, the present invention relates to a silver halide photographic material having a photographically transparent magnetic recording layer and a magnetic recording layer having extremely excellent magnetic recording properties.

(Prior art and its problems) Conventional silver halide photographic materials (hereinafter referred to as "sensitized materials") are
It is almost impossible to input various information (for example, date of photography, weather, magnification ratio, number of prints, etc.) when photographing with a camera, and it is only possible to input the date of photography optically. Furthermore, it is completely impossible to input information to the photosensitive material itself during printing, which is a major obstacle to achieving high speed and cost reduction.

Inputting various information to the photosensitive material is a very important means for improving camera operability and making it simpler in the future. As a means of inputting information, magnetic recording methods are important because they allow arbitrary input/output and are inexpensive, and have been studied for a long time. Appropriate selection of the magnetic recording layer, which has the necessary transparency during photographing and does not adversely affect the granularity, can therefore be applied to the surface of the sensitive material having a transparent support. The provision of the U.S. patent tube 3.
782.947, 4.279.945, 4.3
02.523, etc. Further, a method of inputting signals to the magnetic recording layer is disclosed in World Publication No. 90 4205, World Publication No. 9 (1-04212), etc.

By providing these magnetic recording layers and input/output, it is now possible to incorporate various information into the photosensitive material, which was difficult to do in the past. It became possible to input and output information on the magnetic layer of the photosensitive material, such as the number of copies to be reprinted, the location to be zoomed in, the development of messages, etc., and the printing conditions. Furthermore, it has the potential to be applied as a signal and output means for directly outputting images from photosensitive materials for television/video images.

Japanese Patent Publication No. 57-6576 and Japanese Patent Application Laid-open No. 53109.604, which are prior art related to sensitive materials having a transparent magnetic recording layer.
The magnetic recording layer using gamma ferric oxide, as used in this issue, had low transmittance to light in the visible range.

When only a transparent magnetic recording layer is provided on the entire bank surface of a sensitive material, it is better to minimize the density of the magnetic material in the magnetic recording layer in order to increase the light transmittance. However, it is difficult to extract sufficient magnetic output. Furthermore, in order to increase the magnetic output, it is necessary to increase the density of the magnetic material in the magnetic recording layer. In this case, an inconvenience arises in that the light transmittance becomes low. Therefore, it has been extremely difficult to achieve both optical properties such as light transmittance and magnetic properties such as magnetic output.

On the other hand, as one means for solving this problem, there is a method of installing a magnetic recording layer in a stripe shape outside the screen, as is conventionally used for movie soundtracks. However, with only a striped magnetic recording layer, it is not possible to magnetically record a sufficient amount of information because the width of the stripes is narrow.

It has been desired to develop a system that has a magnetic recording layer that can magnetically record as much information as possible and that also has sufficiently satisfactory optical properties.

(Problems to be Solved by the Invention) Therefore, an object of the present invention is to provide excellent magnetic properties for recording information at the time of photographing, information at the time of processing in a laboratory after photographing, etc. on a silver halide photographic light-sensitive material. The object of the present invention is to provide a silver halide photographic light-sensitive material which is provided with a magnetic recording layer that is photographically transparent as well as a magnetic recording layer that is photographically transparent.

(Means for Solving the Problems) An object of the present invention is to have at least one photosensitive silver halide emulsion layer in the form of a film support, and at least one transparent magnetic recording layer formed of the photosensitive silver halide emulsion layer. A silver halide photographic light-sensitive material having the entire surface opposite to the silver emulsion layer, characterized in that at least one magnetic recording layer is provided in a stripe shape on the transparent magnetic recording layer in a portion other than the screen area. The present invention will be described in detail below.

Ferromagnetic powders commonly used as magnetic materials include ferromagnetic iron oxide fine powder, Co-containing ferromagnetic iron oxide fine powder, ferromagnetic chromium dioxide fine powder, ferromagnetic alloy powder, barium ferrite powder, etc. There is. A zero ferromagnetic alloy in which the acicular ratio of ferromagnetic iron oxide and chromium dioxide is about 2/1 to 20/1, preferably 5 layers or more, and the average length is in the range of about 0.2 to 2.0 μm. The powder has a metal content of 75 wt% or more, and 3 Q wt% or more of the metal content is a ferromagnetic metal (i.e., Fe, Co, Ni, Fe-N15Co-N
i, Fe-Co-N1) particles with a major axis of about 1.0 layer m or less. Any magnetic material may be used as the magnetic material used in the present invention.

Furthermore, the magnetic recording layer may be provided by vapor deposition of a ferromagnetic material such as the one described above instead of the ferromagnetic fine powder.

The magnetic recording layer of the present invention may be provided on the same surface as the silver halide emulsion layer of the photosensitive material, or may be provided on the opposite surface.

Preferably, it is provided on the opposite side of the silver halide emulsion layer.

Since the transparent magnetic recording layer is also provided in the photographic screen area, it must be photographically transparent. The content of the magnetic material in the transparent magnetic recording layer is desirably 4.times.10" to 3 g, preferably 0.01 g to 0.5 g per pot.

The thickness of the transparent magnetic recording layer is 0.1 to 10 μm, preferably 0.1 to 10 μm. It is 2 to 5 μm.

The transparent magnetic recording layer can be provided by coating or printing. Alternatively, it may be provided by a vapor deposition method, a heat fusion method, a tape bonding method, or the like.

Alternatively, a support having a magnetic recording layer may be prepared by co-casting a polymer solution in which magnetic particles are dispersed and a polymer solution for forming the support. In this case, it is preferred that the polymer in which the magnetic particles are dispersed is substantially the same as the polymer for making the support.

At least one striped magnetic recording layer is provided outside the screen. The striped magnetic recording layer may be provided on the transparent magnetic recording layer, or may be provided in the same layer as the transparent magnetic recording layer.

The content of magnetic material in the striped magnetic recording layer is 1rrf0
．． It is desirable that the weight is 0.05 g or more.

The thickness of the striped magnetic recording layer is 0.1 to 10 μm,
Preferably it is 0.2 to 5 μm.

The striped magnetic recording layer can also be provided by the same method as the above transparent magnetic recording layer. There are many methods for stripe coating, such as doctor coat, extrusion coat, slide coat, roller coat, and gravure coat, but in order to perform multi-stripe coating, it is necessary to use these coating heads. It is better to make it multiple. Specific methods of stripe coating include, for example, JP-A-48-25503, JP-A-4B-25504, JP-A-4B-98803, JP-A-50-138037,

Reference may be made to the descriptions in No. 2,181 and No. 3 227.165.

Alternatively, a support having a magnetic recording layer may be created by co-casting a solution of a polymer in which magnetic particles are dispersed and a solution of a polymer for forming the support in a stripe shape. in this case,
Preferably, the polymer in which the magnetic particles are dispersed is substantially the same as the polymer from which the support is made.

In addition, the striped magnetic recording layer may be provided on the transparent magnetic recording layer or may be provided on the same layer at the same time by applying these methods. When provided in the same layer at the same time, it is preferable that the transparent magnetic recording layer and the striped magnetic recording layer have the same thickness. By making the thickness the same, effects such as preventing pressure on the sensitive material and preventing adhesion between the magnetic recording layer and the layer on the opposite side are expected.

The transparent magnetic recording layer and the striped magnetic recording layer can record information such as the number of frames of the photographed screen, the date of photographing, and a user's memo. Information necessary for processing in a laboratory includes, for example, light source information such as the presence or absence of a strobe, information such as screen designation and number of reprints, and information such as zoom position and magnification. Furthermore, it can be used to record signals and information when used as an output means when outputting images directly from the photosensitive material to television/video images. The transparent magnetic recording layer is suitable for relatively low-density magnetic recording, and since the screen portion can also be used, it is possible to obtain a relatively large number of discs. A striped magnetic recording layer is compatible with relatively high-density magnetic recording.

The magnetic recording layer has improved lubricity, anti-static properties, anti-adhesion, and anti-friction properties.
It may also have functions such as improving wear characteristics, or it may provide these functions by providing another functional layer.
If necessary, a protective layer may be provided adjacent to the magnetic recording layer to improve scratch resistance.

Furthermore, a transparent polymer layer containing no magnetic substance may be provided between the striped magnetic recording layers to eliminate the level difference caused by the magnetic recording layers. When this layer is provided, it may have the above-mentioned functions.

After providing the magnetic recording layer, it is also possible to subject this layer to a stress/undering treatment to improve smoothness and improve the S/N ratio of the magnetic output. In this case, it is preferable to apply a silver halide photographic material after calendering.

Before the coating liquid dries, using a cobalt magnet, The treatment was carried out so that the magnetic material was sufficiently oriented.After drying the solvent, an elender treatment was carried out and the film was wound up.Furthermore, magnetic coating liquid 1 was applied to the area other than the screen area above the magnetic recording layer provided on the entire surface. A single striped magnetic recording layer with a width of 4 mm is applied in the length direction using an extrusion coating method.

The striped magnetic recording layer was also subjected to the orientation treatment and calender treatment as described above. Then, an electron beam was irradiated at an accelerating voltage of 165 kV and a beam current of 6 mA to give an absorbed dose of 7 Mrad. Samples were prepared in which the amount of magnetic material in the entire magnetic recording layer and the amount of magnetic material in the striped magnetic recording layer were varied as shown in Table 1.

Similarly, random data is recorded on samples A to H using FM digital signals. Head feed speed is 30m
Let it be m/s. The recording current at this time is kept constant at 140 mA. Recording was performed while changing the recording density. The same head was used to reproduce signals with varying recording densities, the signals were amplified by 90 clB, and a recording density at which the output was 200 mV was found. The output waveform at this time was observed using an oscilloscope, and it was confirmed that the waveform was not so distorted that it could not be read. This operation was performed for each of the entire magnetic recording layer and the striped magnetic recording layer. When inputting to the entire magnetic recording layer and the striped magnetic recording layer at the recording density determined in this way, measure the amount of information recorded in one screen of the entire magnetic recording layer and the striped magnetic recording layer. did. Table 1 shows the relative amount of information recorded in each sample, assuming that the amount of information recorded in sample M coated on the entire surface so that the amount of magnetic material is 0.10 g/rd is 100. It is preferable that the relative value of the information amount is 110 or more. Furthermore, it is more preferable that it is 120 or more.

As can be seen from Table 1, sample A, which is a comparative example,
For G, M, and N, the amount of recorded information is not sufficient.

The sample has too much magnetic material in the screen area, so the transmission density exceeds 0.2, which is unfavorable from a photographic point of view.

In contrast to these comparative examples, samples B-F of the present invention,
H- has a sufficient amount of recorded information and has an excellent transmission density of 0.2 or less.

In particular, the amount of magnetic material in the entire magnetic recording layer is 0.005 to 0.2
Samples C-F and I- where g/n (and the amount of magnetic material in the striped magnetic recording layer is 0.25 g/rd or more)
It can be seen that J is very excellent in both the amount of recorded information and the transmission density.

Furthermore, a striped magnetic recording layer having a width of 4 mm was provided on the entire magnetic recording layer by the method described in JP-A-51-65606. The interval between the stripes was 31 mm. Thereafter, slits were made to a width of 35 mm so that the striped magnetic recording layer was on the outside of the screen area. At this time, the magnetic coating liquid used was one dispersed in the above-mentioned Co-adhered ferric oxide cellulose trioxide dope, with a thickness of 2 μm and a coating amount of magnetic material of 10
A magnetic recording layer of g/rrr is coated. The sample thus obtained is referred to as sample O.

Similarly, samples were prepared as shown in Table 2, in which the amount of magnetic material applied to the entire surface magnetic recording layer and the striped magnetic recording layer were varied.

A photosensitive layer is applied to these samples in the same manner as in Example 1. The surface on which the magnetic recording layer is located is the deflection surface.

Regarding these samples, the transmission density of the screen portion and the relative information amount of the magnetic recording were measured in exactly the same manner as in Example 1. The results are shown in Table 2.

From Table 2, it can be seen that the same results as in Example 1 were obtained.
