i'll admit. i'm a total noob when it comes to printing. But there is somthing i dont get. on the wilhelms research site , their test show that the picturemate from epson last longer then the Fuji Frontier minilabs. Aren't those chemical ? and how can a pigment out last them ?

Depending on the type and materials used color chemical prints last anything from ~10-60 years
The Fuji Crystal Archives rate at over 60 years if produced properly.

Pigment prints on proper archival paper clock in at ~80-120 years.
Or so the accelerated tests seem to say. Come back and check them in 80-100 years to see what really happened.

Dye prints used to be very short lived but even those are claiming very respectable life times now.

Pigments are very stable, and the only real limit to their life is UV exposure, which tends to bleach things. If humidity is controlled, there will be very little chemical reaction with the paper, even if paper is not perfectly neutral.

Chemical process prints tend to keep reacting over time, though very slowly if temps and humidity are controlled, so even if kept in acid-free holders in albums, there is a tendency to yellow.
