Dr. Martin's inks

I am looking for information on Dr. Martin's Inks (a.k.a. Dr. Ph.
Martin's/ Synchromatic Transparent Watercolors/ Analine Dyes).  They
are brightly saturated inks primarily used by commercial artists in
work that is to be reproduced for magazines, etc., and they are
extremely light sensitive and very soluble in water and ethanol (the
same inks are used in  food colors).  My main concern is with early
Andy Warhol prints (1950s) of shoes, cats, and flowers that are most
likely painted with these same inks and have faded to almost
invisible hues.  I would like to know if anyone has encountered
these faded inks on works by other artists (or Warhol), treatment
considerations, or research on the fading mechanisms of the dyes
themselves.
