Do you know which of these apply?
I have no idea what is actually used in the manufacturing process of the films. Since 35mm Neopan is still being marketed, I'm guessing that the chemical wasn't used for its production. I have no idea about Ilford, either. Do a web search, and there's lots of information about the chemical.
