The Adox 400 is based on the formulation of the Agfa APX 400, its emulsion is a little bit faster and anti-halation layer a bit better, it will be manufactured in Germany.
The big problem is, that it isn't possible for Adox to manufacture it at a competitive price at the moment. The 400ASA black and white range of films is still the most competitive section of the market,
we have TMY, TX, BW400CN, HP5+, Delta 400, XP2+, Fomapan 400 and even Fuji will continue to produce the Neopan 400. Actually there is no need of another 400ASA B/W film.
