View Full Version : Adox and Efke

Hi Mirko:

Is the Adox CHS 100 and the Efke 100 film made at the same plant using the same machines? Are the products exactly the same? Again-is there any discernible difference of any kind between the two films, i.e., does one have "built in" hardeners? I ask because there is apparently continuing confusion about the series of emulsions that are the same as the older Adox emulsions, and I would appreciate your "setting the record straight" once and for all.

Dear Mr. Mahler,

if you download our printed catalogue in German you find in respect to ADOX CHS films the following statement as the first sentence:
"These films were previously sold by us under the efke brandname".

The way you pose the question I cannot answer. Efke is a known trademark, so is ADOX and every partner does his business and we both respect the otherīs trademark.

Could you please post the link to the discussions you refer to ?
I would like to answer in detail to the respective customer clarifying the situation. There have been a few changes lately in Fotokemikas products and might have sold longer from stock out of known batches than other vendors.

Best regards,
