In general, the pulp is wound around a core made of pulp, formed into a roll, stored in a light-shielding bag or container, and stored and transported. When the silver halide photosensitive material roll is stored for a long period of time, pressure fogging occurs in the silver halide photosensitive material, or substances released from the core (such as water, formalin gas, acetaldehyde gas, hydrogen sulfide, etc.) It is known that the silver halide photosensitive material may be degraded by the sulfur compound gas or the like, and the core or the silver halide photosensitive material roll hardly causes such deterioration of the silver halide photosensitive material. Have been proposed.

めであると考えられる。In recent years, recycling of paper resources has been desired from the viewpoint of environmental protection, and waste paper pulp is being used for various pulp products. The inventor stores and stores a silver halide photosensitive material roll having a paper tube core formed of waste paper board made of various waste papers such as newspaper, magazine, cardboard in a light-shielding bag, and stores the silver halide photosensitive material after storage. As a result of investigating the state of deterioration of the silver halide photosensitive material roll, the core was a paper tube formed of waste paper base paper obtained by forming waste paper pulp in which ink material remained, and the roll was in contact with the core. It has been found that fogging is likely to occur partially in the silver halide photosensitive material. Although the cause has not been clarified as a result of further studies, it is considered that the ink material remaining on the core directly contacts the photosensitive material.

るという問題がある。In order to solve such a problem, it is conceivable to form a paper tube using only waste paper that does not contain an ink material such as corrugated paper waste. This does not result in recycling and is disadvantageous in terms of manufacturing cost. It is also conceivable to carry out a deinking treatment at the time of pulping, but there is a problem that the production cost of waste paper pulp becomes high.

An object of the present invention is to provide a roll of a silver halide photosensitive material that does not deteriorate.

示す。(Evaluation and Results) The silver halide photosensitive material roll produced as described above was affixed in a light-shielding bag (in the order of light-shielding polyethylene / black polyethylene terephthalate / kraft paper) in a bag shape with the light-shielding polyethylene inside. The opening was double-folded and sealed with an adhesive tape. The light-shielding bag containing the silver halide light-sensitive material roll is placed at 50 ° C. for 3 days, at 40 ° C. for 10 days, and
After storage for 0 days, the state of deterioration of the photosensitive material after storage was observed. The deterioration state was observed by exposing the color paper that had been in contact with the core to gray color, and visually observing the printed image obtained by developing. Table 1 shows the results. Note that A in the table
A indicates that the color tone of the printed image was a uniform gray color,
BB indicates that the color tone of the printed image was a non-uniform gray color.

しながら保管することができる。According to the roll core for a silver halide photosensitive material of the present invention, waste paper can be effectively used. Furthermore, since the core of the present invention is formed only from the pulp material, recycling is easy. The silver halide light-sensitive material roll of the present invention is less likely to cause deterioration of the silver halide light-sensitive material due to the ink material, and further, the occurrence of pressure fogging of the silver halide light-sensitive material is reduced by the neutral paper coating layer. It is possible to store the silver halide light-sensitive material while maintaining the quality thereof.
