The longevity of RC prints is the subject of some controversy. There are
a couple of good papers about the problems on the web page of Thom Bell at:

Thom is with Kodak's
professional customer service department.
Evidently, most of the trouble was caused by oxidation of the Titanium
Dioxide contained in the polyethylene layer just beneith the emulsion. A
scavenger is added to current papers to avoid this problem.
In general, there are a lot of conflicting statements in the literature
about the requirements for long life of silver-gelatin prints and
negatives. :-(
