>From wikipedia:

"...Although the permanency of acrylics is sometimes debated by
conservators, they appear more stable than oil paints. Whereas oil
paints normally turn yellow as they age/dry, acrylic paints, at least in
the 50 years since invention, do not yellow, crack, or change..."

I understand you: 50 years is not enough for having a reassuring feel of
permanence. After a quick search I learned that Getty will organize a
symposium about Modern Paints in May 2006. I bet research on acrylics
will exhibit they're good performers in the permanence department. Lets
see...

Pigment are a known quantity since they have been in used for centuries
and I could say the same about some binders like gum, tempera (eggs),
gelatin, etc. But acrylic as not been around that long and its
permanance isn't a kown quantity as it is for other stuff.
