Not an endorsement, but interesting:
"Epson UltraChrome Inks are water resistant and offer lightfastness ratings
for color images up to 100 years, and greater than 100 years for black and
white prints, on specific Epson papers under non-UV glass.(a) When displayed
under UV-protected glass, color lightfastness is rated at more than 100
years for all Epson's leading professional papers. The quick drying nature
of Epson UltraChrome inks also makes it possible to handle prints the moment
they come off the printer."
