Description

The present invention relates to a silver halide light-sensitive material, and more particularly to a novel silver halide light-sensitive material capable of effectively displaying a positive image obtained by development. .

[Conventional technology]

The silver halide photographic material is constituted by dispersing photosensitive silver bromide or silver chloride throat silver halide grains in a water-soluble binder and coating the dispersion on paper or a plastic support. In a black-and-white light-sensitive material, a developing agent such as hydroquinone, phenidone, or metol is usually used to reduce the exposed silver halide grains to form a silver image, thereby obtaining an image. On the other hand, a color photographic light-sensitive material generally has a silver halide emulsion layer that is sensitive to each of the three primary colors of blue, green and red, and each of them develops yellow, magenta and cyan, and is based on the so-called subtractive method. Reproduce a color image. This color is usually formed by the aromatic primary amine color developing agent, which is oxidized when the exposed silver halide grains are reduced, and the oxidant reacts with the coupler to form a dye. Done.

As a method of observing or displaying the obtained photographic image, in the case of a reflection type positive image, it is general to observe or display as it is under an incandescent lamp, a fluorescent lamp, or sunlight. .

On the other hand, in the case of a transparent positive image, it is generally projected on a screen by a projector or placed on the surface of a viewer for observation. Especially for exhibitions and decorations for viewing by a large number of people, fluorescent lamps are arranged in a flat box and a light diffusion plate (diffuser) or transparent plate (glass plate or transparent plastics) on the surface. Generally, a method in which a transparent positive image is inserted and a panel-shaped object is fixed to a wall surface or the like is common.

[Problems to be solved by the invention]

However, since this method uses light sources such as a fluorescent lamp side by side, it is difficult to obtain completely uniform illumination.
It causes uneven lighting and impairs image quality, and because multiple fluorescent lamps are used, the lighting is likely to become more uneven due to so-called bulb breakage, and the light source is thick, so the panel is thick and space cannot be used effectively. However, it has various problems such as large size because the shape is fixed and transportation becomes large.

[Means for solving problems]

The present invention has been made in view of such problems, and an object thereof is to provide a novel and excellent silver halide light-sensitive material exhibiting an excellent display effect in displaying a transparent positive image, that is, The first object of the present invention is to provide a silver halide light-sensitive material which enables a uniform transparent positive display without causing uneven illumination. The second object is to provide a silver halide light-sensitive material which enables a transparent positive image display with a small thickness. A third object is to provide a silver halide light-sensitive material which enables a transparent positive display which is convenient for transportation. A fourth object is to provide a silver halide light-sensitive material that allows the display surface to have a freely curved surface.

In order to achieve such an object, the present invention provides a silver halide photosensitive material in which at least one photosensitive silver halide emulsion layer is provided on the surface of an electroluminescent support comprising a pair of electroluminescent layers laminated between electrode layers. By providing a material and transmitting a light emitted from the electroluminescent support to a positive image obtained by developing the light-sensitive silver halide emulsion layer, an excellent display effect can be obtained. The point is.

It is preferable that the electroluminescent support is formed by laminating an electroluminescent layer between a pair of electrode layers, and the photosensitive silver halide emulsion layer is provided on at least one of the electrode layers.

Further, it is preferable that at least one of the pair of electrode layers is a transparent electrode, and the silver halide emulsion layer is provided on the transparent electrode.

Further, it is preferable to interpose at least one moisture-proof layer between the electroluminescent layer and the pair of electrode layers.

Further, it is preferable that a light reflection layer is laminated at a position facing the electrode layer provided with the silver halide emulsion layer with the electroluminescent layer interposed therebetween.

Furthermore, it is preferred that the silver halide emulsion layer comprises a laminate having at least three different spectral sensitivities for forming a color image.

Furthermore, it is preferable that the light reflection layer is made of a white pigment.

Further, the electroluminescent layer is preferably formed by dispersing particles containing zinc sulfide in a synthetic resin.

Furthermore, it is preferable that the electroluminescent support is formed of a flexible synthetic resin material.

An electrically insulating light-reflecting layer, 4 is an electroluminescent layer that emits light by an external electric field described later, 5 is a transparent electrode layer, 6 is a transparent moisture-proof film, and 7 is a color or black and white positive image formed by development. Each layer 2, 3, 4, 5, 6, 7 is a silver halide emulsion layer and is laminated on the film substrate 1.

Light is emitted from the electroluminescent layer 4 by applying a DC voltage or a crossing voltage across the electrodes 2 and 4 facing each other on both sides of the light reflecting layer 3 and the electroluminescent layer 4.

A silver halide light-sensitive material having a structure having the silver halide emulsion layer 7 on the electroluminescent support 8 having a light-emitting function as described above is exposed by an ordinary exposure means, and is developed to be transparent by the silver halide emulsion layer 6. A positive image is formed, and the transparent positive image is displayed by the light emitted from the electroluminescent layer 4. As a result, the conventional large-sized light emitting device is not required, and it can be used very easily in an exhibition or the like.

5.0 ml Water was added to 1000 ml The developed sample 201 film was sandwiched between the electroluminescent support used in Example 1 with a glass plate with a thickness of 3 mm, and a predetermined power supply was connected to two electrodes. 201D. The glass plate used was a non-glare type surface-treated to prevent Neutring from occurring due to contact with the film.

Sample 202 was prepared by directly coating a light-sensitive material having the same composition as sample 201 on an electroluminescent support. This was baked in the same manner as the sample 201 and subjected to development processing, and a display panel in which a predetermined power source was connected to two electrodes of the obtained film was designated as a sample 202D.

Both were fixed to a wall in a dark room, and the following measurements and sensitivity tests were performed. When the brightness of the white portion of the image was measured, the comparative sample 201D was 5ft-L, while the sample 2 of the present invention was
02D was 15ft-L. On the other hand, when the images of both were visually compared, the sample 202D of the present invention had a more vivid color and the images looked sharp.

(Effects of the Invention) As described above, according to the present invention, in a silver halide light-sensitive material having at least one photosensitive silver halide emulsion layer on a support, the support is an electroluminescent support. As a result, it is possible to easily create and display a uniform and clear transparent positive image without unevenness of illumination, and because it is extremely thin, flexible, and weighs, it can be used for exhibitions, for example. It is possible to reduce the price, improve workability, and provide excellent workability. Furthermore, since the silver halide photosensitive layer is directly formed on the surface of the electroluminescent support, for example, a conventional positive image is sandwiched between the electroluminescent body and the transparent glass plate or fixed with an adhesive or the like. As compared with the case where the same display effect as that of the present invention is to be obtained, since the integrity is always ensured, it is possible to provide a bright display with high brightness.
