摘要:
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.
摘要:
A method is disclosed of processing in a processor an image-wise exposed black-and-white light-sensitive silver halide photographic material comprising the steps of developing in a developing solution and fixing in a fixer solution, characterized in that upon starting of the processing the said fixer solution comprises a mixture of a fixer starter solution and a fixer replenisher solution, in that said fixer solution is replenished with the said fixer replenishing solution and in that the said fixer starter solution is a developing solution.

摘要:
A silver halide photographic processing solution comprising at least one polymeric compound inhibiting sludge formation and preventing "pi-line" artefact, more particularly in radiographic non-destructive testing applications, wherein said polymeric compound comprises at least one monomer unit having a silver complexing moiety and at least one monomer unit having a solubilising group, and wherein both said silver ion complexing moiety and said solubilising group are comprised in same or different monomer units.

摘要:
For the processing in a total processing time of 60 seconds or less of exposed X-ray materials containing silver bromide or silver bromoiodide emulsions use is made of an aqueous alkaline photographic developing solution, having a pH in the range of 9 to 12, comprising a dihydroxybenzene developing agent, 4-hydroxymethyl-4-methyl-1-phenyl-3-pyrazolidinone as an auxiliary developing agent, at least one organic antifoggant and a compound providing iodide ions.
