“The Konicolor system, introduced by Konishiroku Shashin Kogyo (Now Konica Minolta Holdings, Inc.), split the image into three colors and shot them separately onto three b&w films. In that sense it had something in common with the US ‘Technicolor system’, but this was not a contact print with color dye to create positive film, but used coated emulsion to develop each color in a triple process, which is peculiar. […].”
“In 1930 Mannes and Godowsky were invited to join the staff of the Kodak Research Laboratory, where they concentrated on methods of processing multilayer films, while their colleagues worked out ways of manufacturing them. The result was the new Kodachrome film, launched in 1935. Three very thin emulsion layers were coated on film base, the emulsions being sensitised with non-wandering dyes to red, green and blue light, the red-sensitive layer being at the bottom.” (Coe, Brian (1978): Colour Photography.
