Drew, I knew the designer of Cibachrome and have coated my own versions of it for tests. We were working on a heat processed dye bleach print material at the time. The primary researcher gave a very nice talk at RIT during a convention here and I have copies of that work.

Kodak was working on a version as well, to be called Azochrome. It was coated on a support similar to that of modern Ilfochrome. I have a roll of the support here for my experiments in dye bleach if I ever get around to it. I have already posted single color Magenta here on APUG.
