What chemicals are used for developing film?
Popular developing agents are metol (monomethyl-p-aminophenol hemisulfate), phenidone (1-phenyl-3-pyrazolidinone), dimezone (4,4-dimethyl-1-phenylpyrazolidin-3-one), and hydroquinone (benzene-1,4-diol). Alkaline agent such as sodium carbonate, borax, or sodium hydroxide to create the appropriately high pH.
