Hi Jon,
I understand your problem here, and have worked in "the green
darkness".
You mentioned that the film is a proper black and white (no pink)
when it comes out of the developer, so we can eliminate base color,
anti-hallation backings/dyes, and so on.
I seem to recall running across this sort of thing a couple of times
over the past couple of decades (while doing things that materials
weren't designed for), but no specific solution springs to mind. It's
possible that the proprietary PRD fixer, assuming there was one, may have
had a component that stopped the "pinkage". A documented formula would be
useful.
In the meantime, I have one test and three, wait, ∗four∗ suggestions:
Scrape the back (non-photosensitive side) of the film to see if
there's a backing, and if so, if that's where the pink color resides.
1. Run an extended wash/rinse on the side of the film that holds the
pink. It may eventually clear.
2. Dip a piece of developed pink film in some vinegar. If it clears,
you may need a final trip through a stop bath.
3. If #2 does nothing, try an alkaline bath, like some baking soda
in some water to see if it clears. Sodium carbonate would be better, but
that's not a typical kitchen item.
4. Oh, also, try doubling the time in the fixer, I have a fragmented
memory about "pink" being a problem when Tmax films came out way back
when. The Tmax fixer was very strong and conventional fixers required
twice the time to clear.
I'm just assuming that you haven't tried these yet. I'd appreciate
hearing if any of this helps, it seems like you've been through a lot of
discussion here without getting anywhere.
