I have been interested in the Agfacolor type process (CN17/CNS negative & Agfachrome reversal process) and have done some research and found that after World War 2, the Agfacolor production methods and formulas were made freely available. I also found out that machinery and booty from the Agfa plant were taken east by the Soviets.

With the information and know how so freely available it's no wounder that film companies decided to produce their own films using the Agfacolor type process. Here is an example of different brands of film, all using the Agfacolor/Agfachrome type process.


Was the Agfacolor type process more popular that the Kodak?
If so when did the tables change?
If Kodak was the dominant film type then why did all the film brands in the photo above use Agfa?

I have shown below, my brief research concerning some of the film brands using the Agfacolor type process. This is not a complete list and I stand to be corrected on any points, so please feel free to do so.

In some cases I have only mentioned the colour negative type Agfa film, this is because I could find no information about the reversal, Agfachrome type. I am sure that the film manufactures listed below did produce their own reversal film and that they did use the Agfachrome type process.

Again any information anyone can give would be greatly appreciated

1949 Agfa (Leverkusen) introduced their first colour negative film and in 1952 their first reversal film. In 1978 Agfa introduce their first AP70/C41 negative colour film

1949 Ferrania (Italy) produced their first Agfacolor type negative film. In 1971 they are taken over by 3M, so do they change to a Kodak negative type film when C41 is introduced in 1972?

1951 Telko (Switzerland) introduced Telecolor, an Agfacolor type negative film with the help of Wilhelm Schneider and Alfred Frohlich, both of whom left Agfa (Wolfen) just after the end of World War 2. In 1960 Telko was taken over by Ciba so was that the end of the Agfacolor negative type film?

1957 ICI (England) produced cut sheet colour negative film, called ICIcolor, based on Agfacolor and in 1959 they joined forces with Ilford Ltd and the film was called Ilfocolor. Was this Ilfocolor film an Agfacolor type or Kodak type negative film?

1950's in Japan, Fuji, Sakura and Oriental Photo Industries are producing film and paper based on the Agfacolor process. So when did they change to Kodak process?

In the late 1940's Ansco (Agfa-Ansco USA and later GAF) produced transparency film, Anscochrome based on Agfachrome. I also heard that Ansco produced a negative colour film based on Agfacolor. In the early 1970's they tried to change to a Kodak C22 type film and suceeded only for Kodak to then introduce in 1972 C41 type film. To try and change again to the new C41 would prove too costly (from what I have read) and so GAF, as it was then, bowed out of the film market in the late 1970's.

1953 in East Germany the Agfa (Wolfen) plant becomes state property. They produce film based on the Agfa process both in colour negative and colour reversal films. From my research, it appears that they continued with the same Agfa type films, unchanged, until the early 1990's and after the merger of East and West Germany.

After 1945, Svema (Ukraine/former USSR) and Tasma (Russia/former USSR) receive production methods, formulas, machinery and booty from Agfa and go on to produce Agfacolor negative film and Agfachrome reversal film. This continues until the early 1990's and after the disolution the the Soviet Union.

1962 Gevaert (Belgium) launch Gevacolor-S reversal film. This was not an Agfa type process but a Kodak type process as the film was designed for the US market. In 1964 Gavaert join Agfa to become Agfa Gevaert. So were all the film prior to 1962, Geracolor (not the S type) and Gevachrome based on the Agfa type process or were they Kodak type process.

If you can add to or correct this list then please feel free to do so.
