AFAIK, no publications were made externally on this subject. There might be a research disclosure, but no patent issued. I was not the originator of this idea anyhow, I just worked on it as one of the team members.Originally Posted by fparnold
Basically, it was cuprous oxide precipitated in the dark in a peptizing polymer and then coated. Exposure was normal (blue + uv light) and development was done with sulfuric acid at about 0.1 N. The image could be fixed with sodium hypo.
Hope that helps. It is just OTOMH, and very sketchy now after all of these years.
