Ron, so the no fog increase with heat up to 200 deg. C. you mention in post #5
was not with a traditional emulsion?
These two statements in posts 5 & 9 seem a bit inconruent:
AFAIK, heating to 200 C or thereabouts has no effect on fog.
I never went higher, but that is one test I did run.
"I have gone hotter than that, but 200 C is just fine for me and the film was Estar."
Did you mean to put a knot in #9?
At what temperature does Estar melt?
a) it was a traditional Br/I emulsion.
b) Not so. I used 200 C for processing and had no fog, but I did heat samples of support higher, I just did not make an image on the samples AFAIK. I have forgotten the details of peripheral tests. Sorry.
c) Over 250 deg C. It does deform at the edges at 200 C IIRC.
Ok. Thanks for the clarification.
