Reachrom reversal developer colour.

Ondynne · Apr 28, 2021

So latest this week I stumbled upon this Reachrom - reversal developer colour.
And I was mostly wandering if anybody knows more than me about it, can't really find any information online and thats a bit shocking. It says on the box that is for developing fortechrom and orwochrome films. Regarding anything else I când find from the box. It's full of packs of chemicals and still preserved a small glass bottle ( like a vaccine or medicine one) that stI'll has liquid in it. And is fabricated in Hungary.
I would be glad if i could find anything else about it. Also to maybe try to develop with it would be fun.

You could contact the manufactuer, they are still in business.

I was thinking about that but I can't find anything about them online.

Never heard of them. Being a supplier of lab chemicals today, that once may only have been a niche business to them, but maybe they offered more kits.
Their name though makes me think of photochemicals...

It is reversal sovcolor-compatible process, old version called Diachrome and there are some publication in Russian literature with Diachrome recipe , but very doubtful - it fully repeated Orwo-9165 process, even with the same solutions names, so I'd recommend to use Orwo process (http://analoguephotolab.com/wp-content/uploads/2016/02/C9165.pdf) if you need it. In Reachrome there are maybe some improvement, but I think it almost the same, especially considering than the freshest sovcolor reversal film I've ever see had expiration date in 1997 year.

Thank you I was really confused because I didn't know anything about the preparation process. I still have 2 orwo boxes of developer but they have instructions on the back.
Itsbeen very helpful.

Interesting in this kit is the bottle for the liquid. It s as medical bottle with a rubber membrane under an aluminium cap, originally intended to take up liquids in parts by needle with a medical syringe. That indicates what Reanal was busy with.

It is not unique for such kits, for example, Soviet (and later Ukrainian) ОЧ [Och] kit (https://media2.24aul.ru/imgs/530592...-obrabotki-kinoplenki-och-novyy-1-3751083.jpg) for b/w reversal films contains the same, but large size bottle with 20% NaOH solution.

So this was not done as those bottles were at hand, but as either they were considered as more air-tight or as convinient to draw partial amounts?

I even do not know, why there were liquids in such kits.

Can only say that in USSR such bottles were very popular till 1990-s, it was very difficult to get "usual" with spiral cap.
