Abstract

PURPOSE:To provide the silver halide photosensitive material having an excellent curling characteristic and adhesion resistance and the performance to prevent the deterioration in magnetic characteristics after development processing by providing hydrophilic layers having a specific swelling degree on the opposite side of silver halide emulsion layers provided on a base having a specific thickness. CONSTITUTION:The thickness of the base of the photographic sensitive material having at least one layer of the silver halide emulsion layers and at least one layer of magnetic recording layers on the base is specified to 75 to 116mu. In addition, the hydrophilic layers having <=200% swelling degree are provided on the opposite side of the silver halide emulsion layers. The hydrophilic layers are exemplified by a water-soluble polymer, cellulose ester, latex polymer, water-soluble polyester, etc. The curling characteristic is imparted without degrading the adhesion resistance by this constitution. Further, the adhesive property to a magnetic head is improved and the input and output errors of magnetic recording are prevented by weakening the stiffness of the base.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to silver halide photosensitive materials. The present invention relates to a halogenated B photosensitive material that prevents magnetic output errors.

(Prior Art) Conventionally, silver halide photosensitive JE photosensitive materials (hereinafter referred to as RI) have been unable to store various information at the time of photography (for example, the date of photography, weather, enlargement ratio, number of prints, etc.). It was almost impossible to do it manually, and there was only a small amount of optical photography that could be done manually. Mata, even when printing, it feels +
4. It is completely impossible to provide information to oneself, and this is a major obstacle to speeding up and reducing costs.

Manually inputting various types of information to photosensitive materials is an extremely important means for improving and simplifying the operability of cameras in the future. As a means for inputting information, the magnetic recording method is essential to FFI because it allows arbitrary manual output and is inexpensive, and has been studied in the past.

By adding a magnetic recording layer to the photosensitive material, it is now possible to incorporate various information into the photosensitive material, which was previously difficult to do. Conditions, number of reprints, location you want to zoom,
It became possible to manually output IJt images such as messages, printing conditions, etc. to the magnetic recording layer of the sensitive material. Furthermore, it has the potential to be applied as a signal input/output means for directly outputting images from the photosensitive material to television/video images.

Conventionally, two methods of applying a magnetic recording layer to a sensitive material have been considered: a method in which a magnetic recording layer is provided in a stripe pattern outside the photographic screen, as typified by motion picture film, and a method in which a transparent magnetic recording layer is provided over the entire surface. It's here.

The latter type of sensitive material with a transparent magnetic recording layer is one that has the transparency required for a sensitive material during imaging by appropriately selecting the amount and size of magnetic particles contained in the magnetic recording layer, and also has the granular structure. It is made by providing a magnetic recording layer that does not adversely affect the optical density on the back surface of a sensitive material having a transparent support. Specifically, U.S. Pat. No. 378,294 and U.S. Pat.
It is described in No. 79945, No. 4302523, etc. Further, a signal input method to the 81-ki recording layer is disclosed in Sekaimin No. 90-04205, No. 90-04212, etc.

When magnetic recording is incorporated into a sensitive material, the curling caused by the moisture absorption of the sensitive material and the stiffness of the sensitive material base are stronger than with conventional magnetic recording materials.
In a system in which magnetic recording is applied to a sensitive material, i! ! The magnetic recording layer did not come into close contact with the magnetic head, making it easy for magnetic input/output errors to occur.

A known method of preventing curling due to moisture absorption of the sensitive material is to add a hydrophilic layer to the back side, but it has poor adhesion resistance.
It was only used for a limited number of sensitive materials.

(To be solved by the invention!!!I) The present invention provides a photographic film having a magnetic recording layer.
The object of the present invention is to provide a silver halide photosensitive material that has excellent curling properties, adhesion resistance, and prevents deterioration of magnetic properties after development.
