Yes, Adox was only a brand name not a company, Dr C Fotowerke GmbH was the company and bought by DuPont. On closing EFKE bought the machinery and licenses to make some of the films and papers.

Is Fotokemica EFKE? (FK) Adox were bought out and the machines shifted.
Formalin, eh? Is that even legal? ...
Hi, I got my 37% formalin few years back from a local pharmacy and I also assumed that I'll be fine for years, but it turned out not to be the case. You see, formaldehyde has a tendency to polymerise and I've noticed mine has formed some precipitate. In theory, some methanol is added as a stabiliser, but I guess it doesn't prevent it forever. Meanwhile, I can get it in 1l quantity, but the local pharmacies seem to stopped stocking it...I'm not sure...depends on local regulations I suppose. I was lucky enough to have been gifted half a liter or so of a 10% solution...

You can buy C-41 stabilizer from Maco:Formalin, eh? Is that even legal? Hm. Well, I've still got time to mull on that while I shoot enough to get into that bag. Maybe the local embalmer might tell me somethingLevity aside, duly noted, thanks!
Here are the formula from the British Journal Almanac, 1961.

Right. So I've checked the local chemicals and reagents vendor, and the only thing missing from the British Journal Photographic Almanac recipes is Diethyl paraphenilene diamine, ditto diethyl ppd sulfate, ditto all the aniline-based alternatives. Any idea of what a viable substitute might be?
Are you serious about trying this formula?
Yes or no ..
I did tests and based on those tests I came up with some modifications that produced very good results,,
In fact, I am ready to send you that modified version, but I will not publish that version here, because I always get negative comments that are often cynical, and in fact I can no longer tolerate any negative or sarcastic comments.
If you are serious about this then I can help you wholeheartedly. But just be honest about your passion about trying this process?
These are some of the pictures that were treated with that process in Egypt since last winter.
You need a dedicated developing agent. The various designations for same agent may be confusing though.
In any case you need a Paraphenylenediamine-derivate, which Metol is not. Some earlier european films even seem to have worked with two different derivates. Of the apt derivate then it seems of lesser importance whether you got the Sulfate or Hydrochloride salt.
Okay ,,Oh, absolutely, I'd be delighted! Well, I have a bunch of expired Agfacolor CNS film sitting in the fridge. I was going through the recipes from the British Journal Photographic Almanac, I've already established that I can source everything but the mystery aniline-based component from a local vendor; my knowledge of chemistry is poor, but I have a hunch I could use Metol as a substitute for diethyl paraphenilene diamine/diethyl ppd sulfate (I'd still love someone to confirm that it's a valid substitute). I'd love to take a look at your version. Maybe try out yours, maybe the other one with Metol, maybe both, I have a bunch of film, as I've said… I'm definitely not going to offer any negative commentary; besides, your pictures speak for themselves. How serious am I? Serious enough to buy the chemicals, once I establish which ones I need exactly (I was thinking of using the Ferrania bleach/hardener, for example), and to muck about with mixing them and trying them out. Is that what you'd call a sufficient level of dedication?

Wow, this is excellent information! Saving this seller!!
For example,,, A friend managed to get this item from eBay.
I did not understand your question.Fantastic @mohmad khatab! What is the shelf-life of these colour developing agents from axelcolor?
They sell some items at fairly acceptable prices if you compare them with the prices of that esteemed German merchant.Axelcolor became known at Apug a few years ago. But still they do not list CD-4 or any developing agent at their webshop. But only at Ebay as you found. Weird.
