	The reason Cibachrome dyes are more long lasting
is not for the reason stated in a previous article, but
rather that the Ciba dyes are based on inorganic chemicals,
whereas "standard" (i.e. Kodak) dyes are vegetable-based.
The vegetable based dyes fade pretty easily when placed in
the sun (or with age), whereas the inorganic ones don't.
