Abstract:
1. A silver halide industrial radiographic material comprising on at least one side of a support a hydrophilic gelatinous non-spectrally sensitized radiation-sensitive emulsion layer, having grains, coated in a total amount in the range from 6 to 20 g, expressed as an equivalent amount of silver nitrate per square meter, and at least one non-radiation sensitive protective gelatinous antistress overcoat layer thereupon, wherein a ratio of gelatin to silver, expressed as silver nitrate, in the said radiation sensitive layer is at least 0.70, wherein said gelatinous layers are hardened by a gelatin cross-linking agent in an amount in order to have a dissolving time of at least 40 minutes, said time being measured as time starting when immersing the material in an aqueous solution (1.5% by weight) of sodium hydroxide at 50° C. until the moment that the base becomes visible, characterized in that in the said hydrophilic gelatinous layer arrangement a hydrophilic polymer differing from gelatin is present in an amount of at least 1 g per m 2 .
