摘要： This invention relates to diffusion transfer processes and products wherein the transmission density of the pigmented processing composition layer is increased by employing an alkali earth metal salt to increase the light-absorbing ability of a carboxynaphthol phthalein optical filter agent within said processing composition layer. In another embodiment, a carboxyindole phthalein optical filter agent also is included in said processing composition layer, and a zinc or cadmium salt is employed to shift the spectral absorption of the carboxyindole phthalein into the green region of the visible spectrum. In a further embodiment, a calcium salt is employed in a viscous pigmented processing compositon comprising a light-reflecting pigment, colloidal silica and a metal chelating agent, e.g., an alkylene polyamine polyacetic acid to stabilize the spreading characteristics of the compositions.

摘要： An image-receiving element for use in photographic and photothermographic diffusion transfer film units of the type where the image-receiving element is designed to be removed, or “peeled-apart” from a photosensitive element following exposure and photographic processing. The present image-receiving element comprises, in sequence, a support, an image-receiving layer and a strip-coat layer which serves to facilitate separation of the image-receiving element from the photosensitive element after photographic processing. The strip-coat layer comprises an anion of poly(acrylic acid), or a salt thereof, complexed with a cationic quaternary salt. In a preferred embodiment, the strip coat layer may include an ethoxylated alcohol.
