Arista EDU Fiber Paper

[djklmnop]

Used up more than 25 sheets of Arista EDU Fiber paper to test out two negatives. I've found that that there is a light sensitive dye on the paper. When I turn on the white light the base started to yellow up. I was so worried at first that my fixer had gone wrong somewhere. But in the end, this starts to wash off as it sits in the holding bath. Any idea what this additive is?

I do not know what it is, but I know that it also happens with Oriental VC fiber. Usually washes out in a few minutes. I try to remove as much as possible before determining the right exposure.
