Ansco Color

Agfacolor was the name of a series of color film products made by Agfa of Germany. The first Agfacolor, introduced in 1932, was a film-based version of their Agfa-Farbenplatte (Agfa color plate), a "screen plate" product similar to the French . In late 1936 Agfa introduced Agfacolor Neu (New Agfacolor), a pioneering color film of the general type still in use today. The new Agfacolor was originally a reversal film used for making "slides", home movies and short documentaries. By 1939 it had also been adapted into a negative film and a print film for use by the German motion picture industry. After World War II, the Agfacolor brand was applied to several varieties of color negative film for still photography, in which the negatives were used to make color prints on paper. The reversal film was then marketed as Agfachrome.

Agfacolor Neu, called simply Agfacolor after its predecessor had been retired, was the German response to Technicolor and Kodachrome. Like Kodachrome, introduced by Eastman Kodak in 1935, the new Agfacolor film was an "integral tripack" with three differently color-sensitized emulsion layers. Unlike Kodachrome, the corresponding color-forming dye couplers were made integral with each layer during manufacture, greatly simplifying the processing of the film: with Kodachrome, the dye couplers had to be introduced one at a time during a very complicated development procedure that required special equipment and could only be done at a Kodak processing plant.

Realizing they were at least one year behind their American competitors, German technicians decided to steer away from Kodak’s approach to capturing color images on film and invested on their own technology. Their work bore fruits in the summer of 1936, when chemical engineers of the Agfa company in Germany tested their new material Agfacolor at the swimming competition of the 1936 Summer Olympics in Berlin. Although the German technology promised the use of one and the same material for different purposes, ranging from photographic negative film for prints to photographic slides and motion picture films, it took another three years—until July 1939—for any German motion picture film studio to experiment with the film.
