Does anyone have a formula for Kodak Dektol. thanks once
again in
advance

Larry Kriese

The Kodak formula D-72 is essentially the same as Dektol.
Dektol probably contains some ingredients not in the
published formula such as sequestering agents to prevent
trouble from dissolved salts in the water and whatever Kodak
does to allow the combination of all the ingredients in a
single powder. However, D-72 should have the same
performance.

Kodak D-72 Stock Solution

Water (at about 125F or 52C) 500.0 ml
Metol 3.1 grams
Sodium sulfite, dessicated 45.0 grams
Hydroquinone 12.0 grams
Sodium carbonate, dessicated 67.5 grams
Potassium bromide 1.9 grams
Water to make 1.0 liter

Dissolve all chemicals in the order given.
For use with most modern papers dilute one part stock with 2
parts water.

Nearly every manuacturer of printing paper had some
version of this formula.
