Let's just be grateful that most of Aunt Maude's vacation pictures have faded into oblivion, and also let us hope that most of today's artsyfied inkjet abominations will also fade prompty. Ciba certainly fades if subjected to strong UV commercial lighting or direct sunlight. It seems to be very permanent in the dark. The current Crystal Archive II medium is allegedly a lot more display permanent than Ciba, but
will probably start to discolor within several decades due to residual couplers, regardless of conditions
(except perhaps hermetically frozen). It therefore represents a good value. We all "fade" too.
