Abstract
reversal color images are produced in photographic elements which contain a ballasted primary aromatic amine and conventional ballasted color couplers. The photographic element is imagewise-exposed and a negative silver image is formed without forming a dye image. The residual silver halide in the photographic element is then fogged and developed to silver while concurrently forming a color dye image in the nonimagewise-exposed areas of the element. The developed silver is removed without removing the dye image.
