Other uses for Kodak Ektacolor paper

While cleaning out the back of the studio, I found a bunch of Kodak Ektacolor Supra 2 paper from my color printing days.

Has anybody tried using this paper for the chemigram process or any other alternative photography processes that might use color photo paper?

Thanks

If you still have some RA4 developer, do a test to see how black or what colors are still working. with about 20 year old paper perhaps the yellow dye is less active. I have not used the exact old paper but it probably is still good for chemigrams and photograms. As a hack, i have placed a small RGB led with remote control for the colors over the area where I expose photograms. So I can give it a range of colors. That part you can also do on the color enlarger of course.

After having tried with several older and very old color paper I was pleasantly surprised what is still possible with the old papers.

Old ra4 paper is virtually always fogged beyond reasonable use.

I've used it in the past for pouring carbon tissue on. That's pretty much the only useful application I've found for it.

There's far too little silver in it for chemigrams etc at least in the conventional sense. You could try something along those lines involving a color developer.
