Silver halide photographic industrial X-ray films

Abstract

To eliminate the "pi-line" artefact after processing a silver halide industrial photographic X-ray material is disclosed comprising on at least one side of a support, at least one gelatino silver halide emulsion layer and a total amount of silver halide, corresponding to from 6 to 20 g of silver nitrate per square meter and per side, and at least one non-sensitive protective antistress coating, wherein said photographic material comprises at least one vinyl sulphone compound as a hardening agent and at least one polyoxyalkylene compound as a surfactant in at least one of its hydrophilic layers. A method of image forming in said silver halide photographic material is described wherein after exposure to direct X-rays said material is subjected in an automatic processing machine to the steps of developing in a developer comprising as a surfactant at least one anionic alkylphenoxy and/or alkoxy polyalkyleneoxy phosphate ester, sulphate ester, alkyl carboxylic, sulphonic or phosphonic acid and/or a salt thereof, fixing in a fixer which may comprise at least one alpha-ketocarboxylic acid, rinsing and drying.
