Nothing like that around now.
You could get Ektaflex film for making prints from both negatives and slides, both went through the same processor/chemistry.
I used Ektaflex in the mid 1980s for making OHP slides.
The material used a dye diffusion process. You exposed the film sheet and then fed it with the receiver sheet through the processor that contained a single bath of activator solution.
All the silver stayed in the film layer where the activator released water soluble dyes from the image which diffused to the receiver sheet where they reacted with another chemical that made them insoluble.

As far as I can remember the process was withdrawn in the early 1990s after Kodak lost a legal battle with Polaroid over patent infringement.
