To my knowledge (which may be faulty), "Contact Paper" means that it is intended for contact printing. There is no implication of the chemistry in the phrase. That Bergger's Contact paper contains Iodide is irrelevant to me - if it gives good results. If I insisted on using a pure AgCl paper, I would make my own Albumen paper...

But what I asked was not so much about the paper as about the developer. There is a wealth of information about Azo out there, it is probably the most written-about single silver-process paper in the world. If the question I asked had been the one Michael answered, I wouldn't have asked it but instead read it off his webpage.

So: Anyone have any experience with Bergger Contact G2 in Amidol?
