acetate 'printing paper' for masks and bi-chromate printing

I'm starting to experiment with gum-bichromate printing and need some
material on which I can produce print-sized negs - an acetate coated
with print emulsion. Is there such a thing, which can be tray
developed under a safe light? What makes are there etc.? any info,
thoughts or recommedations welcome.

Also, can such material be used for things such as un-sharp masks, or
contrast masks, but in contact with the printing paper rather than the
negative?

all the best

"Acetate coated with emulsion" usually goes by a much simpler name -- "film"


You're looking for film with an emulsion that resembles enlarging paper.


Kodak Fine Grain Release Positive 5302 film is this material in 35-mm
format:

It is used for making black-and-white movies from negatives.


They used to make it in sheet format, but I don't think they still do.

You could try T-Max 100 sheet film, handled in total darkness of course.<!-- ~MESSAGE_AFTER~ -->
