    Good point. Why is it inside the layers of the film?
    I looked again at the Foma tech sheet. It says that the anti halo layer will decolonize during processing.
    I will test to see if water does it or if the developer does. When does it happen? It is gone after the bleach and before the clearing.

    If developing and or washing were enough remove the anti halo layer no one would have a problem making negatives. Bleach removes it, not washing, not developing, not clear.

    Cut a strip of film and expose it, then lower it into bleach one inch at a time eight times, see if and when the anti halo layer goes away. If so, develop the negative, clear and fix.

    Hmmm ... I wonder what that R100 developer would do to ordinary B&W film.
