I read somewhere, of course I can't find the link now, that ADOX, as both a process and a brand name, had been owned by DuPont. Some time ago DuPont sold the process to Fotokemika, which manufactured the film under the Efke name. Now Fotokemika has purchased the brand name. Does this mean Efke will now become ADOX? Will there be two films under two different names? I don't know.
