In 1941, Kodak made it possible to order prints from Kodachrome slides. The print "paper" was actually a white plastic coated with a multilayer emulsion similar to that on the film. These were the first commercially available color prints created by the chromogenic dye coupler method. In the following year, Kodacolor film was introduced. Unlike Kodachrome, it was designed to be processed into a negative image which showed not only light and dark reversed but also complementary colors. The use of such a negative for making prints on paper simplified the processing of the prints, reducing their cost.
