MCC was an Agfa product so had no link to EFKE/Fotokemika.

The Adox name belonged to Dr C. Schleussner Fotowerke GmbH which was bought by Dupont, they later sold the plant and the rights to make the products under licence to EFKE/Fotokemika. The Adox brand name went out of use in the 1970's and was later resurrected by Mirko/Fotoimpex.
