Mark,

Sorry to hear about your problem. That is a really terrible thing to have
happen to you.

What kind of sleeves were the prints in? Type of plastic that is. Awhile
back there was an issue with the reaction of Somerset Velvet and the release
agents used in some plastic sleeves.

While the optical brighteners will fade an slightly yellow with time it
should take a long exposure to UV light. Had prints been stored with the
open end of the sleeves toward a strong light source?

I am curious as to why this happened to you. I don't use EAM or EEM for
finished prints preferring Photo Rag and German Etching but I do use a lot
of it for proofing and work prints. After 2.5 years I have not experienced
anything like you describe. I wonder if it a paper batch related problem or
something in your particular environment. In any case a change in paper
would seem to be in order.
