I've seen the "slide duplicating film" on eBay so I assume this is perhaps what you mean? Or is that different?

Slide duplicating film is/was used to make duplicate slides ("dupes") from original slides.

Think salespeople being sent out on the road with a slide presentation to be shown to prospective customers.

The original slides stay at the home office, while each of the various reps have their own set of dupes.

The slides that used to be sold at souvenir shops were probably dupes as well.

The duplicating film is/was inherently low in contrast, in order to minimize contrast build-up.
