For your further information, the following is an abbreviated excerpt from
the SPNHC list server, NHCOLL regarding a source for archival-quality
ink:
"Phillip's Process Corp.'s black actinic ink is apparently a very long-lived
magnesium dioxide formulation (will survive a nuclear blast!). It's available
through University Products. No really good archival reds seem to be
available; we've had significant fading of red inks used in the past 50
years, even when stored in darkness. Phillip's (in Rochester, NY) will
make an ochre or a yellow titanium-based archival ink. And interestingly,
they also make (or used to) an archival invisible ink.

Pathology, and L.H. Bailey Hortorium Cornell University, Ithaca, NY

As mentioned in a previous email University Products offers archival quality
materials such as Resistall. Contact: <info at universityproducts.com>
