The first Polacolor was a post-World War II process for making 35mm color motion picture prints for theatrical use. It was a three-color dye coupler process that produced full-color images in a single photographic emulsion. As an alternative to the dominant Technicolor printing process, Polacolor had advantages over the contemporary Cinecolor process, which yielded two-color prints that reproduced only a limited range of colors and had the two component dye images in separate emulsions on the front and back of the film base.
The second Polacolor was an instant film product introduced in 1963 for use in Polaroid instant cameras for still photography. It produced small one-off color prints on paper.
