Wilhelm was giving color xerox materials good longevity several years
ago, about the same as Cibachrome prints, (which by the way aren't as
archival as many people believe them to be. They are archival if you
keep them in the dark, but in the light it's more like 25 years
according to Wilhelm) and longer by far than inkjet prints of the time
or most color photographs. And certainly longer than the SX-70 dyes,
which are notoriously fugitive.
