METHOD FOR CUTTING HEAT-DEVELOPABLE PHOTOSENSITIVE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for cutting a heat-developable photosensitive material, in which a film peeling does not take place at the edges of a section when a continuously running long heat-developable photosensitive material is cut every prescribed length by working a die set comprising upper and lower blades. SOLUTION: The method for cutting a heat-developable photosensitive material is a sheet cutting method in which a continuously running long photosensitive material is cut every prescribed length by working a die set comprising upper and lower blades to continuously produce sheetlike photosensitive materials, and it is characterized in that the sheetlike photosensitive materials are heat-developable photosensitive materials not strengthened by an undercoat layer and having an imaging layer prepared using an organic solvent and cutting is carried out under such a temperature condition that the surface temperature of at least one of the upper and lower blades and/or the imaging layer is between a temperature below the Tg (glass transition temperature) of the imaging layer and a temperature of (the Tg) -30 deg.C or below.
