PE,

I'm pretty sure that it's CD-3 since the formula that I adapted came from "Processing KODAK Motion picture Films Module 7 Process ECN-2 Specifications" document h2407. It can be looked up on the Kodak website.

Nick,
The material used in the final rinse is what matters for image dye stability. Also the bleach was one of many alternatives specified by Kodak. This was only the simplest and cheapest. I'm using Kodak's final rinse which is now formaldehyde free. I checked Kodak's MSDS for there motion picture final rinse. Same chemical.

Mhv,

Correct. The first two are Fuji the second two are Kodak Vision 2.
