摘要： A black-and-white silver halide photographic film material, particularly suitable for use in radiography, has been disclosed, said material comprising a transparent film support having first and second major surfaces coated with a subbing layer, further coated adjacent thereto on one side (for a single-side coated material) or on both sides (for a duplitized material) of said film support and overcoated with a protective antistress layer, a light-sensitive silver halide emulsion layer having chemically and spectrally sensitized {111} tabular hexagonal grains, accounting for at least 50% of the total projective surface of all grains, wherein said film material is coated with a low amount of silver and wherein said protective antistress layer(s)and/or another hydrophilic non-light-sensitive layer comprise(s) a compound according to general formula (I) in an amount of at least 0.5 mmole per mole of coated silver halide, as claimed. A radiographic screen/film combination has also been disclosed, said combination comprising a duplitized film as described herein sandwiched between a pair of supported or self-supporting X-ray intensifying screens emitting radiation in the wavelength range for which said material has been made spectrally sensitive in order to obtain a black-and-white image after exposure of said screen/film combination, followed by processing of the film material.
