DEFINITION

Classification: 430/41

Migration imaging, process, composition, or product, e.g., electrosolography, etc.:

(under subclass 31) Processes, compositions, and products wherein a latent electrical image formed on an element having particulate marking material embedded in or overlying a softenable insulating material and wherein the element is subject to a softening treating step which causes the particles to migrate in an imagewise configuration in the softened material to produce an image. Usually, the particulate marking materials are electrically radiation-sensitive particles and the latent electrical image is formed by electrically charging and imaging the element with radiation. The compositions and products always contain electrically radiation-sensitive particles. These processes are sometimes referred to as electrosolography.
