2. Description of the Related Art In recent years, cameras have become smaller, have improved portability, and have greatly increased opportunities for taking photographs. However, further miniaturization has been desired by users, and miniaturization while maintaining high image quality has been widely studied. The so-called 135 size roll film for general use is loaded in the standard format patrone, which is an obstacle to miniaturization of the camera at present. In order to reduce the size of the cartridge, it is most effective and convenient to thin the film, that is, the light-sensitive material, and it can be achieved by making the thickness of the support of the light-sensitive material thinner than the conventional thickness of about 120 μm.

However, by making the support thin, the strength of the support is lowered, the physical properties of the support and the photographic constituent layers are out of balance, and curls, cracks,
There is a defect that the film peels off and wrinkles occur. On the other hand, JP-A-3-54551 discloses a silver halide color light-sensitive material using a polymer film having a high flexural modulus, and JP-A-3-84542 discloses a photographic film using an amorphous polymer as a support. Cartridges have been proposed.
