Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a variety of image forming materials, and particularly to an image forming material suitable for simultaneously recording solid line images and dotted line images.

Up to now, it has been extremely desirable for information processing to record two or more different types of information on the same image forming material, distinguishing them by solid lines and dotted or chain lines. For this reason, conventionally, different information is recorded on the same image forming material as a solid line image and a dotted line image by converting different information into continuous exposure and blinking exposure, respectively. However, in this method, it is necessary to prepare a light source that provides continuous exposure and a light source that provides flashing exposure as a light source device, which increases the cost of the light source device, and furthermore, it is necessary to form a dotted line image on the image forming material. What should have been an image is not formed as a clear dotted line image.

An object of the present invention is to provide a novel image forming material that can form a variety of easily distinguishable images on the same image forming material through simple operations, particularly a combination of a solid line image and a dotted or chain line image. It is about providing.

Such an object of the present invention is to provide, on a support, (A) a continuous coating layer comprising a photosensitive silver halide;
At least one discontinuous coating layer subdivided into a plurality of small portions containing photosensitive silver halide sensitive to a wavelength range different from the photosensitive wavelength range of (A) is provided. This is achieved through a variety of distinctive imaging materials.

The continuous coating layer and the discontinuous coating layer containing photosensitive silver halide used in the present invention can be formed using known spectral sensitization techniques.
For example, Francis M. Harmer, “The Cyanine Soybean and Related Compounds,” Interscience Publishers,
“The Theory of the Photographic Process” by T.H. James, published in 1964, Vol.
By spectral sensitization using the spectral sensitization technique described in pages 194-290, published by Macmillan Publishing Co., Ltd., 1977 (4th edition), the sensitive wavelength ranges of each coating layer can be made to differ from each other. be able to. In this case, each may have overlapping photosensitive wavelength ranges, for example, one photosensitive wavelength range is 380 nm to 450 nm and the other photosensitive wavelength range is 380 nm to 500 nm, or overlapping photosensitive wavelength ranges may be provided. They may each have completely separate photosensitive wavelength ranges, such as one photosensitive wavelength range from 380 nm to 430 nm and the other photosensitive wavelength range from 440 nm to 500 nm. Furthermore, either the continuous coating layer or the discontinuous coating layer may have a photosensitive region on the short wavelength side or on the long wavelength side.

The coating layer containing photosensitive silver halide (hereinafter referred to as photosensitive coating layer) used in the present invention is as follows:
Ordinary silver halide emulsion layer, photodevelopable silver halide photographic light-sensitive material (for example, Oriental Photo Industries Co., Ltd.)
Manufactured by: "OG-DV", patent application No. 1983-95907, patent application No. 1973
Silver halide photographic emulsion layers applied to heat-developable photosensitive materials (e.g., "Dry Silver" manufactured by 3M Corporation in the United States; Japanese Patent Publication No. 53-41967, A photosensitive coating layer applied to photosensitive materials (such as those described in Japanese Patent No. 54-5687), a silver halide emulsion layer sensitive to various laser beams, and the like can be used. These photosensitive coating layers can be formed into continuous coating layers using conventional methods such as bar coating, bead coating, air knife coating, smooth finishing using a super calender, or grid-like coating layers using gravure printing, screen printing, etc. Alternatively, it can be provided on the support as a discontinuous coating layer in the form of a mesh or halftone dots, or as a discontinuous coating layer in the form of stripes by bead coating, Meyer bar coating, curtain coating, or the like.

In the present invention, when the above-mentioned continuous coating layer and discontinuous coating layer are provided as separate layers (laminates) as shown in FIG. 1, FIG. 2, and FIG. The order may be arbitrary, and a suitable filter layer may be provided between the continuous coating layer and the discontinuous coating layer.
An intermediate layer or the like may be provided, or a top protective layer or a subbing layer may also be provided.
Further, the number of discontinuous coating layers used in the present invention may be one type, or two or more types may be used. For example, when using two or more types of discontinuous coating layers as shown in FIG. It is desirable that the two or more types of discontinuous coating layers that form the various types of images, each consisting of a combination of a dotted line image and a chain line image, have different photosensitive wavelength ranges. It is preferable.

The method of exposing the imaging material of the present invention includes:
This is carried out by selecting a light source from the sensitive wavelength range of the continuous coating layer, and similarly, exposure to the discontinuous coating layer can be carried out by selecting a light source from the sensitive wavelength range. It may be done at the same time or at different times. For example, in the case where the continuous coating layer in the image forming material of the present invention has sensitivity to the short wavelength side and the discontinuous coating layer has sensitivity to the long wavelength side, a light source rich in short wavelength light rays and a light source rich in short wavelength light rays may be used. This can be accomplished by exposing the imaging material simultaneously or at separate times to a light source rich in long wavelength light.

Various types of images are formed by developing the image-exposed image-forming material using a developing method depending on the type of the image-forming material.

Supports that can be used in the image-forming materials of the present invention can be selected from a wide variety of supports. Specific examples include synthetic resin films such as polyethylene, polypropylene, polyethylene terephthalate, polycarbonate, and cellulose acetate, synthetic paper, paper covered with resin films such as polyethylene, papers such as art paper, baryta paper, glass plates, etc. be able to.
