I'm no chemist, but this sounds very much as a photographic layer, not a
photoresist. 

I've read - many years ago - that most photoresist layers are made with
albumine plus several other products to stabilize, sensitize and improve
contrast. A quick search for 'photoresist albumine' popped up several
patents with info on resists.
