Sulfite, not sulfate!
I don't know for sure if that's the same kind of film, but it might be similar. IDK how this film works exactly, only that if you look at the curves, it's pretty much a vertical line instead of a curve. So it's really tailored to give no greyscales whatsoever - which is exactly what you need in its intended application. It's possible that they accomplish this in part by incorporating a developer in the emulsion itself, or something that interacts with the developer. This is what I take from the Reddit post and it makes sense to me. The sulfite pre-bath might act to get rid of those compounds in some way. I'm just familiar enough with this product by far to say anything more sensible about it.
Well, $125 for a roll really isn't too expensive, so I'd just give it a go. Why not? Easy enough and it won't break the bank. It'll be challenging to cut sheets from it without creating kinks in the film, which will likely show up as crescents in the photos. Given its sensitivity there's a good chance you can process the film under green light. There may be safelight instructions to go with it. I doubt you'll be able to use white light because of the blue component, which the film is probably innately sensitive to as well.
It's funny that it comes up because a few months ago I was looking for something like this, but couldn't easily find a roll for purchase locally (without jumping through hoops of making business accounts with b2b distributors etc.), at least not attractively. My idea was to use it to somehow print a halftone pattern on it without using an imagesetter. I have some ideas for that and I'm quite sure that this would in principle work for stuff like carbon transfer. Just one of those many, many things I haven't gotten round to - and likely never will.
