Mab, I would not say that..
Firstly, I am almost sure Adox DOES have coating facility, they are making an emulsion or two in Germany right now (e.g. the new Silvermax that was introduced this year on the Photokina) and they are making papers as well ( some of the brilliant Adox papers or google the process of reviving the FOrte Polywarmtone...) I could imagine that among their investments they could attempt a remake of some classic emulsion, or indeed use some of already made e.g. by Filmotec.
Honestly I don't believe Foma would made such a heavy investment in R&D to make a new emulsion, especially one they didn't manufacutre in recent history...
