Abstract

PURPOSE:To prevent fog due to drying even when the coating speed of an emulsion is increased and to prevent curling of the photosensitive material even when it is stored in a roll state by incorporating a dry fog preventing agent into the same side as an emulsion layer is formed, specifying the glass transition temp. of a supporting body, and subjecting the supporting body to heat treatment at temp. lower than the glass transition temp. before applying the emulsion. CONSTITUTION:The photosensitive body has at least one silver halide emulsion layer on a supporting body and contains a dry fog preventing agent in the same side as the emulsion layer. The glass transition temp. of the supporting body is between >50 C and <200 C, and the supporting body is heat treated at temp. between >40 C and the glass transition temp. The coating speed of the emulsion is preferably >80 m/min. The supporting body is preferably made of polyester such as polyethylene terephthalate and polyethylene naphthalate. The dry fog preventing agent has such an effect to give difference of fog when a photosensitive material with addition of the agent is dried in a coating machine compared to a photosensitive material without addition of the agent, and moreover, the agent gives no difference for natural drying after coating.

The polyester of the present invention has a Tg of 50 ° C.
As described above, the conditions of use are not generally handled with sufficient caution, and the temperature is often exposed to 40 ° C. especially in the midsummer outdoors. From this viewpoint, the Tg of the present invention is safe. The temperature is preferably 55 ° C or higher. More preferably, Tg is 60 ° C. or higher, and particularly preferably 70 ° C. or higher. This is because the effect of improving the curling habit by this heat treatment disappears when exposed to a temperature exceeding the glass transition temperature, so that the temperature is a severe condition when used by general users, that is, the temperature exceeds 40 ° C in summer. Polyesters having a glass transition temperature above the temperature are preferred. On the other hand, there is no general-purpose polyester film which is transparent and has a temperature higher than 200 ° C. Therefore, the Tg temperature of the polyester used in the present invention needs to be 50 ° C. or higher and 200 ° C. or lower.
