Inkjet dispersants, need to keep the pigments in better suspension
than "fine art grade" colors. But Wilhelm says that HP inks are pretty
darn near indistructable, giving them over a 200 year fade resistant
rating. 

Some of the most high-tech developments in archival, large gamma
colors have come because of the ink jet industry in the last 10 years.
It's hard to predict exactly how "archival" our products really will
be. I guess we'll find out in another 100 years or so. Amazing, how
well some of the pigments from early art have stood up to the ravages
of time and light.
