You could try it with fluorescein dye which can be bought online in various forms. Fluorescein looks like it is a basic dye so it might require a mordant on the print paper in order to transfer well--perhaps chrome alum? Other fluorescent dyes include Rhodamine which comes in two forms, one of which is available in art stores. You might also use a dye-toning method to create a photographic image in fluorescent dye, cf. J.S. Friedman "History of Color Photography." If Frizza is really interested in fluorescent images he might find it easier to start off with the materials commercially available than try to find compounds made of rare earths.

Try drawing with the dyes also. This will give you a sense of what the fluorescent images look like.
The Reason I don't want to initially start trying with fluorescein dye or the other commercially available products is because I'm not after something that renders a semi accurate colour or a basic rendition of reality Iam more interested in achieving a good natural luminescent colour from a totally clear / invisible coating.
as was hinted in this test.

PE one question I have is when such test items were made did kodak have a vault for all these such test items to be filed and cataloged if not simply for future reference? As in could the actual example you saw exist stored in a vault somewhere? I simply ask because I keep a process diary and often file away the more important things i make in tests. I wonder if kodak does the same of only keeps written records of their experimental items?
