Actually, permanent means forever. After all, it is permanent. So how long
is permanent? Illfochrome has materials that they will guarantee for 150 -
200 years or more depending on how they are handled. these specialty
microfilm materials are, after all designed for permanence. Yes, some are
perminent...visit any museum that displays some of the Old Masters. Earth
pigments tend to be as permanent as possible.

My Dye Transfer Prints and many existing Technicolor Motion Picture Release
Prints are still with us, and in perfect condition. I have a Dye Transfer
that has been displayed in my parent's home for 20 years and it matches the
one that has never been displayed. Dyes are indeed stable. Unfortunately,
some believe that Dyes because they are Dyes, are not permanent. This is
far from the truth. There are a number of special dyes that have been
developed to withstand exposure to High Pressure Sodium Lamps without
loosing more than 3% density over an expected and Accelerated test lifetime
of some 100 years. Want to buy some, they are Spanart Dyes and cost about
$3,000.00 per dram.
Later on, Dye Transfer was developed and popularized by Eastman. Here

I did not say they were not, what I said - (clearly pasted above) is that
Fuji can't say that they have a proven track record for longevity.
Kodachrome came along before Fuji - excluding some of the early research
materials I have seen from Fuji. So far, my Kodachromes have not faded and
they are from the first materials that came off the production line. BTW: I
have some 8 X 10 Kodachromes used as display transparencies that are still
perfect, as are my Kodachrome Prints. So their track record is more or less
unbroken. After all, if you make something and it lasts till this very
moment without problems, it is as permanent as possible until it does fail.
BTW: Fuji has no materials suitable for long term archival storage of
images. They recommended that we use an archival Microfilm material, and
sugested that we search the Web for info.
