PROBLEM TO BE SOLVED: To provide a thermoplastic substrate easy to be cut, with reduced occurrence of flashes by slitting and drilling, and to provide a silver halide photosensitive material with scarce troubles on pictures. SOLUTION: The thermoplastic substrate has breaking strength of 5 to 18 kg/mm2 both in TD and MD directions, elongation at break of 20 to 140% both in TD and MD directions, and deviation of crack tear resistance of 0.3 to 1.8 kg/mm2 both in TD and MD directions. The silver halide photosensitive material utilizes the support.
