Yves,

Henry Wilhelm's research on the archival
qualities of pigment images on white polyester
(as in the Ultrastable printing system) was on
the order of 500 years.

What is the source of the information about the
fugitive nature of the transparency materials to
which you refer?

For sure, you pose an important question.
