摘要
The present invention provides a silver halide photographic photosensitive material in which a silver halide photosensitive layer is disposed on a transparent polyethylene terephthalate (PET) film into which an ultraviolet light absorber has been kneaded, wherein the ultraviolet light absorber is at least one kind of ultraviolet light absorber characterized in that (i) a loss of mass is not greater than 10% when heated to 300° C. at a heating rate of 10° C./minute in a nitrogen gas atmosphere, and/or (ii) a difference between a b-value of a sheet having a thickness of 1.5 mm formed after heating for 1 minute at 300° C., a PET resin including an amount of 0.4% by mass of the ultraviolet light absorber and having a water content of not greater than 50 ppm, and a b-value of a sheet having a thickness of 1.5 mm formed after heating the PET resin for 8 minutes at 300° C., is not greater than 3.0.
