Abstract: The present invention relates to a symmetrical radiographic assembly comprising:a double side radiographic element which comprises a support and hydrophilic colloid layers coated on each side of said support, andan intensifying screen adjacent to each side of said radiographic element,wherein on each side of said support are coated at least two silver halide emulsion layers having a speed difference of at least 0.5 logE and an average contrast difference of at least 0.

Abstract: Light-sensitive silver halide photographic materials comprising a support base and one or more hydrophilic colloid layers, at least one of which is a silver halide emulsion layer, at least one of said hydrophilic colloid layers of said photographic materials containing both a) a non-ionic surface active agent having a polyoxyethylene group and b) a fluorinated organic compound, characterized by the fact that said fluorinated organic compound is the reaction product of a polyoxyalkyleneamine compound and a fluorinated organic acid compound.
