Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide photographic light-sensitive material having a light transmitting portion and a light shielding portion. The silver halide photographic light-sensitive material of the present invention can be used for forming a mask material that selectively blocks transmission of light having a specific wavelength. Such a mask material can be suitably used, for example, as a mask used when making a film original for printing.

[0002]

BACKGROUND OF THE INVENTION A material having a light transmitting portion and a light shielding portion is used, for example, as a mask which selectively shields light having a specific wavelength. As an example of such a mask, a mask film used in a printing plate making process. There is.

For example, a general process from a print original such as a handwritten design original when making a color print consisting of characters, pictures, and a flat screen to a film original plate which is a final film for exposing the printing plate to light. Is generally as shown in FIG. That is, the designer creates a design original drawing called a rough sketch or the like, and gives necessary color separation instructions to each character, line drawing, and flat screen portion together with the overall design and layout. That is, with respect to each color of yellow, magenta, cyan, and black (hereinafter sometimes referred to as Y, M, C, B / K, etc.), the instruction of the color and the density thereof is manually given. Based on this, the typesetting is done and the block copy of the manuscript is created. A mask plate is created by creating a mask plate based on a negative film obtained by photographing this block copy with a camera.

This mask is for blocking unnecessary portions in order to prepare a film original of each of the required four colors. For example, if there are four characters "Otenki" and each character is Y, M, C, B / K, mask other than "O" to create a film original for Y, while other than "TE". The mask is used to make a film original plate for M, and the mask is selectively used according to each color to make film original plates for each of the four colors. At this time, the colors to be used are not always the primary colors of Y, M, C, and B / K, and therefore, in order to develop the intermediate colors, it is necessary to paste. At this time, the flat mesh is aligned and attached to the corresponding mask in accordance with the mesh% designation specified in advance. Finally, a flat screen character mask is applied to the character negative film, a flat screen and a flat screen mask are also applied to the negative film, and a pattern mask is overlaid on the disassembled negative obtained by disassembling the photographic original with a pattern mask. The film is subjected to multiple printing to prepare a plate-collection positive film for each of yellow, magenta, cyan and black.

As the photosensitive material for printing plate making used as the plate-collecting positive film, one having a spectral sensitizing wavelength in a wavelength range of 300 to 500 nm is widely used so that it can be handled in a bright room where ultraviolet rays are cut. As a printer for exposing such a light-sensitive material, one having a light source such as a high pressure mercury lamp, an electrodeless lamp such as MD and AEL, a V bulb, a quartz halogen lamp, a metal halide, etc. is known.

The mask used in the above process must have a high resolving power because it must selectively transmit or shield even a minute portion of the original.

On the other hand, as such a mask, conventionally,
A transparent plastic film, which is mainly a polyester film, having a peelable actinic ray-shielding masking film on one side has been used. Conventionally, a mask pattern is created by cutting the masking film with an instrument having a sharp tip such as a knife and peeling off the film inside (or outside) the part surrounded by the cutting line. Means were used. Alternatively, there is also a means of forming a cutting line by using a photographic method, that is, printing a block copy into a black-and-white photograph and using it to form a cutting line, which enables cutting with a considerably fine pattern. However, even in this case, the work of peeling itself still required manual work.

With the spread of automatic cutting systems using CAD systems in recent years, the cutting speed can be increased even with complicated patterns. However, since peeling is a manual work, it takes a long time to lift the portion of the masking film to be peeled off with a knife along the cutting line and peel the masking film from the surrounding support with fingers. It was

The peeling operation takes a very long time because the thickness of the masking film is usually as thin as about 20 to 40 μm and a knife or the like easily reaches the support film so that the operator does not break the masking film. It is also necessary to work carefully so as not to damage the support. Further, even with sufficient care, the masking film of the pattern to be left may be scratched in some cases. Therefore, these corrections also took time. Further, the peeled masking film may be re-adhered or may be attached to the fingertip or the surface of the masking film to cause defects in the masking original, and removal of these is complicated and time-consuming work.

The above problems are particularly important in the present situation where the shortage of skilled workers and the shortage of workers (manpower) have become serious in recent years.

When the printer material is exposed through the mask material to the printing plate-making photosensitive material, the light-transmitting part of the mask material gives the printing plate-making photosensitive material a sufficient exposure amount for the image format, and the light-shielding part is the light source of the printer. It is necessary to block the light and protect it from light. It is considered that the photosensitive material for printing plate making generally has a high gradation and can separate the image part and the non-image part with a relatively small light amount ratio, and the density difference between the light transmitting part and the light shielding part of the mask material is sufficient. Is. However, for example, when separating characters that are close to each other with a mask material, the mask material obtained by forming a dye image by exposure and development to form a light-transmitting portion and a light-shielding portion has good separation of close characters. I found that there was a problem that it was difficult to do.

Since the mask material is generally used by being laminated with a negative film or a base having a flat screen attached,
If they stick to those materials or if they slip badly, the workability is significantly impaired. The conventionally used peelable masking materials have room for improvement in this respect.
A matting agent can be used to improve this point, but in the mask material formed of a silver halide photographic light-sensitive material, the halftone quality of the finally obtained plate-collecting positive film is significantly deteriorated. It turns out there is an unexpected problem.

[0013]

SUMMARY OF THE INVENTION Each of the inventions of the present application has the above-mentioned problems, that is, an image having a high resolution must be obtained as a mask material, and the formation of a mask pattern is complicated. In view of the fact that it is difficult to clearly separate the characters etc. that have been printed, the aim is to solve these problems, and the halftone quality of the final positive plate obtained is good and the workability is good. An object of the present invention is to provide a silver halide photographic light-sensitive material suitable for making a good mask.

The density difference ΔD with respect to any wavelength in the wavelength range of 1 may be a density difference sufficient as a mask material, but the density difference ΔD is preferably 2.0 or more. Preferably, ΔD is 2.2 or more.
ΔD can be adjusted by the coating amount per unit area of a dye image forming substance such as silver halide and a coupler used in combination with silver halide. Further, it can be adjusted by activating the developability of the silver halide emulsion and increasing the image density. Further, it can be adjusted by using a stronger developing solution, extending the developing time, or raising the developing temperature. It can also be adjusted by methods such as increasing the reactivity of a dye image-forming substance such as a coupler or using a compound having a high absorption coefficient of the dye. These means can be used alone or in combination.

The exposure light source for exposing the silver halide photographic light-sensitive material according to the invention of the present application is a laser light source. As a laser light source used for exposure, various laser light sources can be used. As a laser light source, He-
Ne (wavelength: 633 nm, etc.), semiconductor laser (wavelength:

The transmission density of the photographic constituent layer on the side having the emulsion layer in the light-sensitive material according to the present invention measured by the wavelength of the laser light source used as the exposure light source is measured by using a commonly used transmission type density measuring device. This can be easily measured by measuring the transmission density at the wavelength. That is, the value of the transmission density obtained by measuring by peeling off the non-photosensitive layer on the opposite side of the photographic material before processing from the emulsion layer side with the support, and the photographic constituent layer on the side further having the emulsion layer Also, the difference in transmission density obtained by peeling and measuring only the support is taken as the transmission density of the photographic constituent layer on the side having the emulsion layer. In the light-sensitive material according to the present invention, this value is 0.6 or more, more preferably 0.8 or more.
