Diffusion transfer photographic elements with polymer grafted pigment

摘要

A diffusion transfer photographic element composed of a photosensitive sheet, a cover sheet, and a processing composition contained in a rupturable container in such a manner that the processing composition is spread between both sheets after exposing the photosensitive sheet is disclosed. The whiteness of highlights of images obtained is improved by incorporating a graft carbon black polymer prepared by graft polymerizing a monomer to carbon black in the photographic element, in particular, in the light-shielding layer of the photosensitive sheet. The graft carbon black polymer prepared by graft polymerizing a monomer to carbon black can be uniformly dispersed in an aqueous medium and thus the photographic properties of a diffusion transfer photographic element can be improved using the graft carbon black polymer.
