  The present invention provides a dye diffusion transfer imaging process for the production of retained images, comprising the steps of: - applying an alkaline aqueous processing composition to an image-wise exposed photographic element that contains in operative association with an alkali-permeable silver halide hydrophilic colloid emulsion layer a redox-activatable compound that initially is immobile in an aqueous alkali-permeable colloid medium and is capable of releasing under alkaline conditions in reduced state a diffusible dye moiety, - providing a silver halide developing agent in said photographic element for being present therein during application of said alkaline aqueous processing composition to cause as a function of development of said silver halide emulsion layer the release of said diffusible dye moiety from said redox-activatable compound upon reduction thereof at the non-silver image areas or the loss of the capacity of said redox-activatable compound of releasing said diffusible dye moiety upon oxidation of said redox-activatable compound at the silver image areas, and - allowing diffusion of said diffusible dye moiety into an extracting liquid or disposable receptor medium and leaving in said photographic element a silver image as well as an UV-absorbing dye image retained congruously with said silver image, said redox-activatable compound comprising at least two dye units together absorbing radiation all over the range between 300 and 450 nm. The present invention also provides a photographic silver halide element comprising such a redox-activatable compound.

  本发明提供了一种用于制作保留图像的染料扩散转移成像工艺，包括以下步骤： - 将碱性水溶液冲洗组合物应用于图像曝光的感光元件，该感光元件含有与透碱卤化银亲水胶体乳剂层有效结合的可氧化还原活化的化合物，该化合物最初在水性透碱胶体介质中不移动，并能在碱性条件下以还原状态释放可扩散的染料分子、 - 在所述感光元件中提供一种卤化银显影剂，以便在使用所述碱性水性冲洗组合物期间存在于其中，从而在所述卤化银乳剂层的显影过程中，使所述氧化还原活化化合物在非银图像区域还原时从所述氧化还原活化化合物中释放所述可扩散染料分子，或使所述氧化还原活化化合物在银图像区域氧化时失去释放所述可扩散染料分子的能力，以及 - 允许所述可扩散染料扩散到提取液或一次性受体介质中，并在所述感光元件中留下银图像以及与所述银图像一致保留的紫外线吸收染料图像、 所述氧化还原活化化合物由至少两个染料单元组成，共同吸收 300 至 450 纳米波长范围内的辐射。本发明还提供了一种包含这种可氧化还原活化化合物的照相卤化银元件。
