Ok, here it is as an attachment.
A bit to large, oh well, a google for Kodak L9.pdf will bring it up.
Even with the original post, it has less to do with sourcing than listing of certain chemistries available at that time. Few links. And it reviewed chemistries with opinions that had little basis in experiential fact. Sorry, Greg.
A lot has happened in C-41 chemical availabilities since the original post. (I can't speak to RA-4, as I don't do that process. But I imagine something similar.) B&H won't ship liquid chemistries, nor do they stock much. But for someone in Manhattan willing to wait, it's still a source. Freestyle has attained the Rollei/Compard and Tetenal liquid chemistries.
http://www.artcraftchemicals.com now has all the individual chemicals you need to make C-41 from scratch, if that's your gig. I did some calculating, and for about $108 plus shipping you can get everything you need to make 45 liters. The chemical that runs out at that point is the half pound of CD-4. There are various amounts of all the other chemicals left at that point. Also chemicals to make your own bleach and fixer, if you wish.
Mi dos centavos.......
Then by all means, go for it. Do the research on what is available and where to get them. I already did it once and am satisfied with my supplier.
So I used the Rollei kit from Freestyle and I'm not sure I like it. What other kit is a 4-chemical kit (no blix for me), and where can I get it? Especially locally, I'm in the San Francisco Bay Area. Thanks.
The Unicolor powder kit (It's $19 for a 1 liter and $33 for a double dip) provides a Blix A envelope, Ammonium thiosulfate and postassium carbonate. Obviously the fixer ingredients.
The Blix B envelope contains "Sodium iron EDTA", sodium sulfite, and "PDTA." The latter's CAS number tells me it is "1,3-Propylenediaminetetraacetic Acid ." I found this about that: "[I]A specific chelator especially developed for the photo-finishing process. When it complexes with iron, it is very effective in the bleaching of photographic films and paper." [I] Obviously the bleach components.
The individual baths would require appropriate pH adjustments, I'm guessing. I can't speak to those matters. Point being here that the Unicolor powder chemistry can give you seperate bleach and fix.
