Silver halide photographic photosensitive material having a polyethylene terephthalate film base support into which ultraviolet light absorber is kneaded

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 for which 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.

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 absorber represented by the following general formula (1):

• wherein X1, Y1, and Z1 each independently represents an alkyl group, an aryl group, an alkoxy group, an aryloxy group, an alkylthio group, an arylthio group, or a heterocyclic group, which groups may each be substituted or unsubstituted, with the proviso that at least one of X1, Y1, and Z1 represents a substituent represented by the following structural formula (A):
• wherein R1 and R2 each independently represents a hydrogen atom, a halogen atom, an alkyl group, an alkenyl group, an aryl group, an alkoxy group, an aryloxy group, an acyloxy group, an alkylthio group, an arylthio group, an amino group, an acyl group, an oxycarbonyl group, a carbamoyl group, a sulfamoyl group, a carboxyl group or a salt thereof, or a sulfo group or a salt thereof, which groups may each be substituted or unsubstituted, and adjacent R1's and R2's may join together to form a ring.
