Okay, so I know that Azo is a silver chloride paper. Everyone is always talking about the joys and capabilities of silver chloride papers. But what's the significance of the name? Surely there's some azo compound in the paper? What is it? Is it in any way chemically similar to the azo dyes I read about in other photographic papers like ciba/ilfochrome? In general, are Azo papers (Kodak and non-Kodak) unique because of some combination of silver chloride and azo compounds, that might separate them from non azo containing silver chloride papers? Sorry, lots of technical questions I know.
