I seem to remember a short UK ban on North Atlantic tinned Tuna due to Cadmium in the 11980s, while Cadmium levels in Tuna was properly assessed.
Record Rapid without Cadmium did not keep well.
Agfa used slightly different names in North America and Europe.
Here in the UK/Europe, Portriga Speed was the RC version of Record Rapid (Gloss FB), and Portriga was a Pearl/Satin not quite Matte FB paper. It was nor uncommon for products exported to North American to have slightly different names. It was about preventing Grey imports.
In the late 1970s I experimented with a Cadmium Toner, this gave White tones, you would ask why . . . . What about an emulsion on a black surface. at the time I had a business applying emulsion to painted surfaces, usually cars, vans, etc, for advertising. This was before Vinyl transfers.
