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.
