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.
