So much for relying on memory.
After searching several sources I find that Agfa used a green sensitizer for several of its paper products. Some used Erythrosine and some used a dye which as I reported before is unknown (hier ist unbekannt) and they also used a method of applying the dye(s) either in overcoats or added to the emulsion just before coating. It is not clear regarding this either. In any event, at least two dyes were used in Agfa papers and up to two methods were used to incorporate them.
Sorry for the lack of clarity in the last post. I was working from memory. Now I have notes, such as they are.
