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.
摘要翻译：公开了一种由感光片，覆盖片和包含在可破裂的容器中的处理组合物构成的扩散转印照相元件，使得处理组合物在曝光感光片之后在两片之间展开。通过引入通过在照相元件中，特别是在感光片的遮光层中将单体接枝聚合到炭黑上而制备的接枝炭黑聚合物来改进获得的图像的亮度的白度。通过将单体接枝聚合成炭黑制备的接枝炭黑聚合物可以均匀地分散在水性介质中，因此可以使用接枝炭黑聚合物改善扩散转印照相元件的照相性能。
