Carl,

John Paul Caponigro gave the following values in his review of the
Ultrachrome in the Sept./Oct. issue of Photo Techniques:

Preliminary Henry Wilhelm "longevity ratings" in 7-color mode:

Premium Glossy Photo Paper - 90+ years
Somerset Velvet for Epson - 80+ years
Premium Luster Photo Paper - 50+ years
Premium Semimatte Photo Paper - 40+ years
Enhanced Matte Paper - 30+ years

I gather the "+" signs indicate that testing is still in progress.
