There was some recent discussion of dye stability in color printing.
The latest issue of Science-84 has an article on exactly that subject.
Overview:
1. Most color prints made today are very unstable, whether
stored in darkness or exposed to light. Cold storage
dramatically increases the life expectancy.
2. Instant print film is stable in the dark, but very unstable
in light.
3. Cibachrome is highly stable.
I have one question. What about the dyes in slide film? I use slide
film exclusively, printing my favorite shots. Are the slides subject
to fading as well? I haven't looked back at any of my old slides to
check this out.

As far as I know, the dyes used in chromogenic materials such as Koda- chrome, Ektachrome, Agfachrome, Fujichrome and most other "chromes" are some- what unstable. Chromogenic materials also contain residue color couplers that discolor with time. (I was going to say more, but it's almost 3 am). The bot- tom line is: Kodachrome dyes have good dark stability. Ektachrome dyes have better light stability. Cibachrome dyes have better light and dark stability than either of the other two. -jim@nosc (zaun)
