(1-phenyl-3-pyrazolidinone) is an organic chemical compound whose
primary use is as a photographic developer.
- It has five to ten
times the developing power as Metol.
- It also has low
toxicity and, unlike some other developers, does not cause
dermatitis upon skin contact.
- One of the most novel
properties of Phenidone is the efficiency effected because it is
re-activated by Hydroquinone.
developing properties are dependent on the pH of the solution.
- Phenidone is slightly
soluble in cold water, but as the temperature of the solution
increases Phenidone becomes more soluble, It is readily soluble in
both acid and alkaline solutions.
- Ilford claims "That a
Phenidone -Hydroquinone developer is More Effective Than Any Other
Available Developer For Forced Development Where Last-Ditch
Exposures With Minimal Highlight Blocking Is Desired."
- Phenidone gives no fog
with Low-Speed emulsion papers. However, with high speed emulsions
it may produce fog.
- Benzotrlazole added to
a paper developer compound with Phenidone, not only prevents fog,
but also has the effect of modifying the Tone Of The Silver Image so
that Cold Blue-Black Tones are produced.
- The final oxidation
product of a Phenidone -Hydroquinone developer is COLORLESS, which
reduces, but does not eliminate, the staining of fingers and
clothes. This is due in part to the Hydroquinone.
