KODAK D-85
From Photo Lab Index:
Sodium Sulphite 30 g
Paraformaldehyde 7.5 g
or 37% Formalin Solution 20 mL
Sodium Bisulfite 2.2 g
Boric Acid 7.5 g
Hydroquinone 22.5 g
Potassium Bromide 1.6 g
Water 1 L
From the web:
Part A:
Sodium Sulphite 36.5 g
Boric Acid 9.4 g
Hydroquinone 28 g
Potassium Bromide 2 g
Water 1 L
Part B
Sodium Bisulfite 11 g
Sodium Sulphite 1 g
Paraformaldehyde 37.5 g
4 Parts A + 1 Part B for use, which yield, when combined:
Sodium Sulphite 30.2 g
Paraformaldehyde 7.5 g
Sodium Bisulfite 2.2 g
Boric Acid 7.52 g
Hydroquinone 22.4 g
Potassium Bromide 1.6 g
Water 1 L
So they are the same!
Developing time: Two to six minutes for all materials.
Temperature: 20C +- 1C Agitation: Constant
The developer works best when used in a one shot mode, mixing Parts A and B together immediately before use. It is a reasonable replacement for Kodak Kodalith Developer for lithographic materials. Can be used to develop holographic recording materials in any type of configuration, and is especially good at forming a surface relief on low spatial frequency diffraction gratings..
Shelf life: 6 months for each solution unmixed, in stoppered bottles
