That is the problem. No other company has admitted to using non-polar couplers and the data on that is not in the BIOS or FIAT reports. I have read them as pertaines to the German companies and have talked personally to the members of the Japanese photo industry. I have samples of Agfa, Fuji, Oriental and Konica films and their processes. The products used the same process at the time I last used them in 1960. So, I hesitate going beyond what I have read in the reports or heard from the actual individuals involved.
