Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a photographic material with improved physical properties, and particularly to a photographic material with improved sliding properties.

``Prior Art'' Photographic light-sensitive materials usually have a surface layer containing a hydrophilic colloid such as gelatin as a binder.
In addition to manufacturing processes such as processing, photography, development processing,
During handling such as winding, rewinding, or transportation during printing, projection, etc., undesirable damage may occur due to contact friction with various substances or contact friction between photographic light-sensitive materials, such as between the surface of the light-sensitive material and the back surface. often affected.

For example, the occurrence of scratches or abrasions on the surface or back surface of the photosensitive material, poor running properties of the photosensitive material in a photographic machine, printer, or camera, and generation of film waste.

In particular, poor running performance is a serious problem when continuously shooting long lengths of film such as negative film for movies, and if the running resistance of the film is large, camera noise, film scraps, double images, etc. will occur. becomes. Various studies have been conducted to solve this problem.

One method is to reduce the sliding friction of photographic materials so that they can run smoothly inside photographic devices and cameras without being damaged.

For example, there is a method as described in US Pat. No. 3,042,522 in which dimethyl silicone and a specific surfactant are simultaneously included in a photographic emulsion layer or a protective layer to impart slipperiness to a photographic film.

A mixture of dimethyl silicone and diphenyl silicone is coated on the bank surface of a photographic material as described in British Patent No. 3080317, or a fatty acid ester of a polyhydric alcohol as described in British Patent No. 1466304. There is also a method described in British Patent No. 1,143,118 in which slipping properties are imparted to a photographic window material by incorporating triphenyl end-blocked methylphenyl silicone into the protective layer. In addition, as a means to improve adhesion prevention, scratch resistance, and slipperiness, inorganic substances such as silicon dioxide, magnesium oxide, and titanium dioxide may be added to the surface layer of a photographic light-sensitive material, which is made of a hydrophilic colloid using gelatin as a binder. The so-called Methods of matting to improve adhesion prevention, scratch resistance, and slipperiness are widely used.

However, when attempting to improve the in-camera running properties of photographic film using these known methods, although each has some effect, it is not sufficient, and other sensitization effects often occur.

For example, if silicone is applied to the base backing layer, it is true that the sliding friction of the backing layer can be greatly reduced, but when the film is actually passed through a camera, the running properties are not improved much, and camera noise and film scraps occur. occurrence of
Double images were frequently observed.

On the other hand, when a matting agent (fine particle powder) was applied to the surface layer (protective layer or backing layer) of a photographic light-sensitive material by a known method, there was certainly a considerable improvement in adhesion prevention and scratch resistance. However, almost no improvement effect was obtained regarding running performance.

Furthermore, the backing layer of the known method using a capping agent is a hydrophilic colloid layer containing gelatin as a binder, and has poor running properties compared to a hydrophobic binder.

``Problems to be Solved by the Invention'' An object of the present invention is to provide a photographic light-sensitive material with improved in-camera running properties.

That is, the object of the present invention is to provide a photographic material that can smoothly drive camera gates such as film magazines, camera gates, and projector gates, and that does not generate noise or cause double image failure.

"Means for Solving the Problems" The object of the present invention is to have at least one silver halide emulsion layer on one side of a support, and at least a hydrophobic binder, a slip agent and a fine particle powder on the other side. The surface layer of the backing layer contains at least a hydrophobic binder and a slip agent.

The binder used for the backing layer in the present invention is a binder mainly composed of a hydrophobic polymer such as a cellulose ester derivative such as cellulose acetate, a synthetic polymer such as polyacrylic acid ester, or polystyrene, and is non-photosensitive. It may have a single-layer structure or a multi-layer structure, but in the case of a multi-layer structure, the hydrophobic binder and the slip agent are contained in the surface layer.

The slip agent in the present invention is not particularly limited, and may be any compound that reduces the sliding friction coefficient of the object surface when it is present on the object surface compared to when it is not present.A compound that reduces the sliding friction coefficient. The selection is made by dissolving the compound in a solvent, then forming a coating layer on the cellulose triacetate substrate so that the concentration ranges from about 1 mg to 500 mg/d, and measuring it using the method for measuring the coefficient of static friction shown in the examples. I can do it.

Further, since some hydrophobic binders include compounds that reduce the coefficient of sliding friction, the hydrophobic binder can also serve as a slip agent in this case.

Typical slip agents used in the present invention include, for example, U.S. Patent No. 3,042,522 and British Patent No. 955.

Further, the polymer in the present invention may be polymerized in the presence of a so-called crosslinking agent having two or more polymerizable double bonds to form a crosslinked polymer.

Furthermore, the dispersion stability can be improved by forming hollow particles. Among these, particularly preferably used polymers are homopolymers of polymethyl methacrylate, polystyrene, polyacrylonitrile, glycidyl acrylate, or copolymers thereof.

As the inorganic compound, silicon dioxide, calcium carbonate, magnesium oxide, titanium oxide, aluminum oxide, etc. are preferably used.

In applying the compound of the present invention to a hair bath surface, specific examples of preferred binders having film-forming ability to be used together are shown below. cellulose triacetate,
Cellulose diacetate, cellulose acetate maleate, cellulose acetate phthalate, hydroxyalkyl alkyl cellulose phthalate (alkyl group has 1 to 4 carbon atoms), hydroxyalkyl alkyl cellulose tetrahydrophthalate (alkyl group has 1 to 4 carbon atoms)

When using a binder, organic solvent mixtures can be used as solvents.

When using a binder, use an organic solvent or a small amount of water or a binder that is compatible with water. A mixture with six agents can be used as a solvent.

It will become clear from the Examples described below that the structure of the present invention is extremely superior to the object of the present invention, and the differences from the conventional technology will be shown below. In the prior art, for example, many dimethyl silicones, which are well known as slip agents, have excellent performance in significantly reducing sliding friction when applied to the bathoking layer of photographic materials. The actual running performance in the camera is insufficient, and by using a matting agent in the photosensitive material to roughen the smooth surface layer, physical properties such as adhesion prevention and scratch prevention can be improved. Although it is well known in patents etc. that it can significantly reduce sliding friction, and furthermore that it improves the actual running performance inside the camera, the fact is that it has almost no effect. do not have.

The patents for the use of mantle agents in photographic materials so far have been for application to protective layers or backing layers consisting of hydrophilic colloid layers containing gelatin as a binder.

On the other hand, the structure of the present invention consists of using a combination of a slipping agent and a matting agent in a backing layer made of a hydrophobic binder.

In this way, when used individually for the purpose of the present invention, almost no effect was obtained on the actual running performance in the camera, but it is extremely clear that the configuration of the present invention shows excellent effects. This is surprising. This is probably due to the synergistic effect of the three functions of the slip agent, capping agent, and hydrophobic binder.

In carrying out the present invention, when the backing layer of a photographic light-sensitive material is composed of one layer, a solution of a slipping agent and a dispersion of a matting agent are added to a solution of a hydrophobic binder in an organic solvent and applied. Further, in the case of a multilayer structure, the matting agent does not necessarily need to be in the surface layer, and if the surface is uneven, the manting agent does not need to be included in the surface layer.

Incidentally, the slip agent may be added at the time of synthesizing the cape agent.

The amount of the slip agent and capping agent used in the present invention is 5 to 500 mg, preferably 20 to 100 mg, per square meter of the bank layer.

Further, the thickness of the bank layer is used in the range of 0.02 to 10μ, preferably in the range of 0.1 to 2μ.

In the photographic light-sensitive material of the present invention, any support that is normally used as a support for photographic light-sensitive materials can be used. Examples include cellulose acetate film, acetose acetate butyrate film, polystyrene film, polyethylene terephthalate film, laminates thereof, and paper.

Examples include paper coated or laminated with a polymer of α-olefin of 0.

Examples include partial hydrolysates. Compatible mixtures of two or more of these colloids are used if necessary.

Among these, gelatin is the most commonly used.

The photographic emulsion layer and other layers used in the present invention contain synthetic polymer compounds, such as latex-like water-dispersed vinyl compound polymers, in particular compounds that increase the dimensional stability of photographic materials, either singly or in combination.

Example 1 A coating solution for a backing layer was prepared by adding the compounds shown in Table 1 as a capping agent and a slipping agent to 8 liquids of Methanol-J with hydroxypropyl methyl cellulose hexahydrophthalate as a binder, and a triacetyl cellulose photograph was prepared. A binder is coated on the film support so that the dry backing thickness is 0.2 μm.An undercoat layer is provided on the opposite side of the base backing layer, and on top of this is an antihalation layer, a red-sensitive emulsion layer, a gelatin intermediate layer, A color negative emulsion for motion pictures consisting of a green-sensitive emulsion layer, a yellow filter layer, a blue-sensitive emulsion layer, and a protective layer was sequentially coated. Silver iodobromide emulsions each containing 6 mol % of iodine were used as the red and green emulsions. A silver iodobromide emulsion containing 8 mol % of iodine was used as a blue-sensitive emulsion. After aging for one week, cut into 35m/m and 16m/m widths.
A 0 foot roll of film was obtained. The test items are (

Each evaluation method is shown below.

SMPTE, 80 (91734-739 (197)
Using the paper clip method described in 1), the maximum static friction coefficient of the film back surface was determined.

(2) Fix the camera aperture plate and pressure plate ARRIFLEX 35 (A) manufactured by CARNOLD & RICFITER on the pull-out resistance force measurement moving table. After inserting the sample between the Ava chair plate and the pressure plate and fixing one end of the sample to the load cell, the moving stage was moved at a rate of 10 m/1 line, and the maximum frictional resistance force of the film generated at that time was determined.

(3) Measurement of Noise The cut roll-shaped film was run using an Arton camera (16 mm film camera, manufactured by Ari Corporation) to measure noise. Noise was measured by converting the noise in the camera into voltage using a Jorso Audio Spectrum Analyzer while running the film on a camera hanger. Since the pitch of the sound is converted into voltage in proportion to it, the lower the voltage, the less noise there will be.

(4) Photographing a double image The cut roll-shaped film was photographed using an Ariflex BL3 camera (for 35 mm film, manufactured by Ari Corporation),
Is the film exposed after processing? Double image (image shift) observed with XX mirror due to poor running during shooting.
The distance was measured.

These evaluation results are shown in Table 2.

As is clear from Table 2, Samples 5 to 9 of the present invention have low static friction coefficients and film pull-out resistance measured as a proxy for runnability, and are low in noise when actually runnable. No double images occurred.

However, although sample floors 1 and 2 used for comparison had low static friction coefficients and low pull-out resistances, they had high noise and double images.

In addition, floors 3 and 4 of the comparative samples had a large static friction coefficient and a large pull-out resistance, and had high noise. There was also a large discrepancy between the double images.

As mentioned above, the static friction coefficient and pull-out resistance measured as a proxy for running performance must be small, but it is necessary to actually run the vehicle and measure noise and double images, and the present invention is superior in both. I understand.
