Cor-
The Darkroom Cookbook say the following.... take it for what it's worth....
"Uses: Organic antifoggant and density depressant in developers.
Benzatriazole acts as a restrainer without effecting other properties of
the developer. It can be used as a fog restrainer when processing outdated
papers.
When true black image tones are desired with bromide papers, benza.
should be used in addition to, or substituted for, pot. bromide. Make a
0.2% solution of benza. (2 grams in water at 125*F to make one liter) then
reduce the bromide to 1/10 or 1/6 strength and use just enough benza.
solution to prevent developer stain or fog. Some experimentation will be
required...."
"Notes: Benza. does not dissolve readily in cold water. Use hot water @
125*F or higher."
"Trade names: Edwal's Liquid Orthazite, which containes approx. 3%
solution of benza. with sodium sulfite. Kodak Anti-Fog #1 (no longer
manufactured.)"
Hope this is of some small use.
Happy New Year-
