ABSTRACT:
To eliminate the "pi-line" artifact after processing a method of image formation is disclosed in a silver halide industrial X-ray photographic material, comprising on at least one side of a support, at least one gelatin 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 material further comprises a hardening agent different from a vinyl sulphone compound, preferably formaldehyde, and at least one polyoxyalkylene compound as a surfactant in at least one of its hydrophilic layers, and 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 at least one anionic alkylphenoxy polyalkyleneoxy phosphate ester surfactant, fixing in a fixer which may comprise at least one alpha-ketocarboxylic acid, rinsing and drying.
