There is an Arista high speed darkroom duplicating film that
I've used. Its intended to create contact-sized negatives
by enlarger projection from film negatives. It can be
processed, using a red safelight, in convetional b&w
paper chemistry. It works very well. The only
drawback is that it beats up on chemistry,
particularly fixer, as there is a lot of silver.
