Abstract An imaging method is disclosed comprising providing an imaging member comprising a first layer of softenable material containing migration material overlying a second layer of softenable material which is substantially free of migration material wherein at least one of the layers of softenable material contains a surface skin located at the interface between the layer of softenable material. This member is latently imaged and developed by softening whereby the migration material migrates through the first layer of softenable material and the interface, where the surface skin is located, and in depth in the second layer of softenable material thereby forming an imaged member. Background of the migration material is then removed from the imaged member by splitting the member at the interface thereby obtaining an image with excellent imaging properties.
An imaged member comprising: a first layer of softenable material containing a background of migration material, said first layer of softenable material overlying a second layer of softenable material, said softenable material being either electrically photosensitive or substantially electrically insulating, said second layer of softenable material containing migration particles distributed in depth in said second layer of softenable material in image pattern configuration, at least one of said layers of softenable material containing a surface skin located at the entire surface of at least one of said softenable layers and at the interface between said layers of softenable material, said surface skin formed by exposing said surface of at least one of said layers of softenable material to hardening radiation sufficient to form said surface skin having a thickness from about 0.01 to about 0.5 micron.
