ABSTRACT:
A migration layer comprising migration material and softenable material, said migration layer having a set electrical latent image. The process of setting the electrical latent image comprises providing an imaging member comprising the above migration layer, electrically latently imaging the migration layer and setting the electrical latent image by either storing the migration layer in the dark or applying heat, applying vapor, or applying partial solvents in a pre-development softening step. After setting of the electrical latent image, the migration layer can be exposed to activating electromagnetic radiation without loss of the latent image and permitted long delays of up to years between formation of the electrical latent image and the development step which allow selective migration in depth.
