I have acquired a roll of Ektachrome 7242. I know this is really ancient stuff i.e. 1960-70.
I know this is a ME-4 process or something like that. This process has some sort of a pre hardener before the first developer. This is to prevent the emulsion from turning into jello and falling off due to 100f temps.
What I want to know, is it possible to formulate that pre hardener and then use it before E6
chemicals to finish the process?
If so does someone have the recipe for that hardener?
Also another question along similar lines. Are Ektachrome 7251/2 films VNF-1 films?
Is VNF-1 close enough to E6 to work? Will it stand up to the elevated temps?
