PURPOSE:To prevent bleeding from the end part of a photosensitive layer during taking up and preserving and to improve preservation stability by coating the end part of a roll with a sheet-shaped desiccating agent. CONSTITUTION:After a photosensitive film 2 formed with the photosensitive layer is wound on a cylindrical winding core 1, the roll end part of the laminated element is coated with the sheet-shaped desiccating agent 3. The photosensitive film having the photosensitive layer refers to the film obtd. by forming the photosensitive layer on a plastic film such as polyester film. A photosensitive resin compsn. consisting of, for example, a film property imparting polymer, ethylenic unsatd. compd. and initiator which generates a free group by active rays, etc., are used for the sheet-shaped desiccating agent resin. The bleeding of the photosensitive layer from the roll end part of the laminated element is effectively prevented in this way. |
