Ilfochrome, (more popularly known as Cibachrome) is a dye destruction positive-to-positive photographic process used for the reproduction of slides on photographic paper. The prints are made on a dimensionally stable tri-acetate polyester base, essentially a plastic base opposed to traditional paper base. Since it uses azo dyes on a polyester base, the print will not fade, discolor, or deteriorate for a long time.
