Abstract of the Disclosure This invention relates to photographic film structures for forming color transfer images viewable by reflected light without separation of the photosensitive and image-receiving components and to diffusion transfer processes employing these unitary film units wherein a dye is initially positioned in the image-receiving component to offset the color stain that tends to form in the high- lights of the transfer image during aging. Any dye or mixture of dyes may be employed which are capable of absorbing visible light in a wavelength range comple- mentary to the wavelength range absorbed by the color stain and are used in a concentration such that the high- lights, i.e., Dmin areas of the transfer image, appear substantially white after aging, as observed by the eye. In a preferred embodiment, the dye employed is a dye developer.
