Can I process this paper in RA-4 chemicals? For photograms...

I advise you to shoot it with a large format camera.
It will give you great results.

That's very kind of you to suggest that, thank you, but my question was can It be processed in RA-4 chemicals?

I am not ashamed to say I do not know, or rather I am not sure.
But I think that maybe it can work, and maybe there is another process for that category of paper.
I'm really not sure, because I'm not a print specialist and I've never been to print before. I only develop films.

I am quite sure this paper is based on the Agfacolor couplers.

Well, paper is now over 40 years old, or when did the Czech Republic split with Slovakia? You can contact Foma, they might know.

Hello my dear colleagues, Allow me to participate in this discussion.
The answer is also directed to the colleague Anton Lukoszevieze who had a similar query on this topic, so the answer is for both of you.
Some thoughts have lit up in my mind, and I almost think that I might have found the answer at the prestigious Agfa Foundation.
In fact, there are solutions, and there are formulas, some of which are adjustable and applicable, and through my long experience with Agfa formulas, I testify that they are formulas that have great flexibility towards making after modifications and replacing some elements.

But it is really costly to an extent, not a little in terms of money, and it takes a lot of effort and a lot of time in order to conduct many experiments and tests.
It requires the purchase of chemical raw materials, preparation of solutions, developers, and so on, which requires time, effort and money.
So I'm wondering, is it worth it?
If the answer is yes,
Well, it's okay, we can start doing this research together.
Yes, this ancient forum was originally established in order to conduct those experiences and conduct those researches.
But you must be ready to spend money, effort and time.
I need to hear an honest answer and an honest promise about it.
If the answer is yes, or no.

You can even try to develop this paper in usual b/w chemisty (in full darkness), these kinds of paper had high silver content, more than modern b/w paper.

It is processable in RA-4 at lower temperate (25 or less), but I'm afraid you will get monocolored image of purple or orange fog. Sometimes people find suitable for prints without high colored fog, for example, the internet auction for such paper, third photo:

This is really interesting thank you, I am actually using different colour papers for abstract colour photograms, such as the one attached. I tried this paper in RA-4 chemicals and got different colours....which is good.

Operation Ra4 will not work
If you are interested in getting record results, take a look here

This is the outcome in C41 chems:



I made test with Polaroid Land 420 camera

Not necessarily "over 40 old", but at least 30 years.
