摘要： A self-contained silver halide diffusion transfer imaging sheet is provided which contains three layers on a substrate. The first layer is a silver halide emulsion formed in a non-ionic material. The intermediate layer is a water barrier. The third layer is a nucleating region which contains collodial silver. A developer, base and silver transport agent can also be located in these layers. For example, the base and silver transport agent can be located in the nucleating layer, with the developer located in the emulsion layer. After the emulsion is exposed to actinic radiation, a non-aqueous activating medium is supplied which initiates the development and diffusion transfer processes. The final result is a positive image in the nucleating layer.
摘要翻译： 提供了独立的卤化银扩散转印成像片，其在衬底上包含三层。 第一层是在非离子材料中形成的卤化银乳剂。 中间层是水屏障。 第三层是含有胶体银的成核区域。 开发商，基地和银运输代理也可以位于这些层。 例如，碱和银输送剂可以位于成核层中，显影剂位于乳剂层中。 在乳液暴露于光化辐射之后，提供非水活化介质，其启动显影和扩散转移过程。 最终结果是成核层中的正像。
