| titleOfInvention | Photographic developing solution for use with fore-hardened x-ray films |
| abstract | An aqueous alkaline photographic developing nsolution that is especially adapted for use in the ndevelopment of fore-hardened X-ray films has a pH in nthe range of 9 to 12, is substantially free of both naldehydic hardening agents and silver halide solvents, nand comprises (1) a dihydroxybenzene developing agent, nsuch as hydroquinone, (2) at least 3.5 grams per liter nof developing solution of a 4,4-disubstituted-1-aryl-n3-pyrazolidinone, which functions as an auxiliary nsuper-additive developing agent, such as 4-hydroxynmethyl-4-methyl-1-phenyl-3-pyrazolidinone, (3) an nalkaline agent, (4) an organic antifoggant, and (5) a npreservative. The developing solution is capable of nbeing packaged as a single part formulation and nprovides a very short process time and excellent nsensitometric results. |
