The trade name Adox was owned bt Dupont, when they ceased manufacture of film & paper the machinery went to Croatia -the EFKE factory.
EFKE used to sell their films & papers using the Adox brand name. However this ceased in the 80's or 90's and the films were then branded as EFKE.
But thats to answer those that posted later.
You asked about Adox paper: I've ben using the Adox/Forte/Classic Arts/Berger Polywarmtone FB paper (its all the same) for nearly 2 years now, and it's superb. I just wish I'd started using it earlier.
