There's been much posting here and elsewhere about the elimination of cadmium from fiber-based printing papers. Discussions usually relate to possible effects on image quality. I'd appreciate anyone with detailed information on the chemistry involved sharing what they know about how unexposed paper storage life might be affected.
This question is posted with an eye toward acquiring a large quantity of Azo. Although it is an extremely slow paper, and has a reputation for lasting virtually forever without fogging (suffering only a slight reduction in contrast after many, many years), I'm concerned that recent changes might have diminished its long-term keeping qualities.
Thanks in advance for your inputs.
