Abstract
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.
