Premier Art has told me they are using some titanium dioxide in some
coatings, but I could not get details.  That is not a fluorescing OBA, but
just very white and stable.

The Premier Art Smooth BW that I'm using with the Eboni-6 inkset is the
brightened version of the Hot Press, which is the archival standard as far
as I can tell.  The BW is also made to be as stable as possible.  It has
probably at most a third of amount of OBAs as the Matte BW you tested, and
it's a better paper, so I'm hoping it'll be quite stable.  I have not tested
it yet, however.  On the good papers the fading is usually not more on the
brightened than the natural versions, it's just a matter of the OBAs fading.
