In recent years, it has been strongly desired to reduce the amount of processing waste liquid from the viewpoint of environmental protection and space saving. Especially, in the medical field,
The waste liquid associated with the wet processing of the image forming material poses a problem in workability. As a countermeasure against these problems, a photothermographic material has been developed which forms a photographic image by using a photothermographic method which does not generate a processing waste liquid.

In such a photothermographic material, a reducible silver source (eg organic silver salt), a catalytically active amount of photocatalyst (eg silver halide), and a reducing agent are dispersed in a usual (organic) binder matrix. It is contained in the state. The photothermographic material is stable at room temperature, but when heated to a high temperature after exposure, it produces silver through a redox reaction between a reducible silver source (which functions as an oxidizing agent) and the reducing agent. This redox reaction is promoted by the catalytic action of the latent image generated by exposure. The silver produced by the reaction of the organic silver salt in the exposed areas provides a black image, which contrasts with the unexposed areas and forms an image.

The photothermographic material is a coating solution for forming a photosensitive layer in which an organic silver salt, a silver halide and a reducing agent are dispersed in an organic binder matrix on a support made of a belt-shaped plastic as described above. Is thicker than the photosensitive layer of a conventional photographic photosensitive material, and the photosensitive layer is directly coated and dried without coating the undercoating layer that the conventional photosensitive material adopts for film strengthening, and is wound onto a shaft. After that, a sheet-like product is manufactured by cutting it into a required width and then cutting into a required length.

Usually, in order to obtain a sheet-shaped photosensitive material by cutting these long roll-shaped photosensitive materials, an upper blade and a lower blade are made while the long rolled photosensitive material is moved intermittently or continuously while running. Are assembled into a die set, and the die set is operated like a punch die to perform cutting to a predetermined length. Further, for continuous production, a long roll of photosensitive material is cut while sequentially connecting it with a joining tape.

When the photosensitive material having the photosensitive layer coated on the plastic film is cut by such a cutting method, the following problems are mentioned.

First, since the cutting blade causes a compressive deformation due to a strong compressive stress in the cut portion, if the photosensitive layer is not deformed in accordance with the compressive deformation of the plastic film, film peeling of the photosensitive layer occurs at the cut surface. Occur. On the other hand, when the connecting portion comes to the cutting position, the adhesive of the joining tape adheres to the cutting blade and the cutting cannot be continued.

Regarding the problem of film peeling of the photosensitive layer, there was no film peeling which would be a failure in the conventional photosensitive material which has been strengthened with a film in the undercoat layer. In the case of a non-reinforced photothermographic material, the coating film of the photosensitive layer is easily peeled off from the end of the cut surface, and the coating film of the photosensitive layer at the end often becomes slightly floating.

When the film peeled off from the cut surface adheres to the surface of the photosensitive material as described above, an image is not formed due to exposure loss during exposure, and the film brought in by the processing device adheres to the transport system. A cutting method has been developed in which film peeling does not occur because it leads to an accident such as a transport trouble.

The film peeling of the photosensitive layer at the time of cutting is likely to occur on the cut surface when the cutting method is the pressing method. Not only for heat-developable photosensitive materials, but for cutting weakly adhered laminates, the rotary slitter with upper and lower blades in contact with each other, such as bending shear cut, has no clearance and can suppress deformation of the material. It is known that the film peeling is unlikely to occur, and when the upper and lower blades are cut with a certain clearance, the film peeling can be suppressed by making the blade angle of the upper and lower blades acute.

[0012] For example, Japanese Patent Laid-Open No. 2000-233863 discloses a method of making a cutting edge sharp as a cutting method for suppressing material deformation during cutting. Particularly, when the edge angle of the upper blade is set to about 30 °, it is said that the deformation of the material is extremely small and the excellent cutting result can be obtained in which the peeling of the photosensitive layer is very small. However, the sharpness reduces the strength of the cutting edge, and when high-speed mass production is attempted, costs and time are required for polishing and replacing the blade.

In order to obtain a sheet-shaped photosensitive material by continuously cutting from the rolled photosensitive material, when the rolled photosensitive material is used up, the next rolled photosensitive material is connected by a joining tape and continuously. Is disconnected. Usually, the cutting part and the joint part of the cutting device are fixedly arranged. On the other hand, there are multiple cutting lengths to meet market demands, and there is no problem if multiple cutting devices are installed. However, due to the capacity of the cutting device and the layout area of the cutting device, a single device can be used for various types of products. It is generally compatible with.

At this time, the problem is that when the connecting portion is cut, the adhesive of the joining tape adheres to the cutting blade,
The quality is reduced. If the cutting length is constant or if there is more than one cutting device according to the cutting length, the cutting device should be adjusted in advance according to the cutting length and the length from the cutting part to the joining part of the cutting device should be decided. By designing, it is possible to avoid cutting the connecting portion, but it is not possible when one cutting device is compatible with many kinds. In a cutting device that cuts many types of products like this, with respect to the adhesion of the adhesive tape of the joining tape of the joining part to the cutting blade, generally, just before the joining part enters the cutting part of the cutting device, A method is adopted in which the cutting is temporarily stopped and the joint is artificially avoided, and then the cutting is performed, which is one of the causes of lowering the production efficiency.

Cutting proceeds by receiving compressive shearing force and tensile force. At this time, it was found that the photosensitive material was deformed by the compressive shearing force of the cutting blade, so that peeling occurred between the support and the photosensitive layer having different deformation amounts, and so-called film peeling occurred.
