Do they state that on their web page or elsewhere?  I've never seen that claim.  It could be very interesting if true (as opposed to what some salesman says at a booth).

I think the approach I'd like to see more of is balancing the paper bleaching with an OBA that fades at the same rate.  I called the ink version of this a "counter-fade" strategy when I incorporated  the concept in the original MIS FSN inkset.  HP may use it in their neutral inks -- at least it appears in their patent disclosures.  I think H Photo Rag gets its stability from such an approach also.

Like the Epson "Archival" 7500 inks -- just ignore the black end with its hybrid pigment-dye K and it looks a lot better.  Wilhelm has contributed a lot to the field, but to really know what is going on, we need the details.
