   I have this material somewhere and will try to find it.
Kodak used two kings of laquer on Kodachrome slides and on
color prints. One can be removed using a mild soluton of
Sodium carbonate, its the solvent for the other I can't
remember. Nor which should be tried first if one does not
know for certain which laquer was used. The coating on
prints turns yellow with age. If you have old Kodachrome or
Kodacolor prints that have yellowed its probably only the
laquer coating.
   I don't know for certain but I don't think Kodak used
this laquer for any film other than Kodachrome.
