FUJIFILM Fujicolor Crystal Archive Type II Paper (8 x 10", Lustre, 100 Sheets)

This is color photo paper. It is light sensitive and is only used for making darkroom prints.

You could, just laminate the photos for repelling liquid, etc...

Yes, this would.

I've tried it in a pinhole camera with a direct positive alternative process. From memory, I tried with a exposure index of around 5, so that could be a starting point for experimentation. However, you need to do color filtering in-camera, or your print will be mostly cyan. With an actual lens, a cokin #002 orange filter gave OK-ish results; the same filter with a pinhole still gave a mostly cyan image, so there may be some color-dependent reciprocity failure once your exposure gets long enough. (The process I used was BW paper development in the dark, stop, turn on lights, wait a bit, then RA-4 development and bleach/fix with the lights on.) I haven't tried using it for paper negatives, but I'd expect similar problems at typical pinhole exposure times. (Of course, you could then at least try to color correct when contact printing afterwards.) The paper works very well as a normal RA-4 color darkroom paper, though.
