Abstract
Abstract An imaging system comprising providing an imaging member comprising an agglomerable layer in contact with an imagewise hardenable-softenable layer and imagewise hardening said member. An image is developed by imagewise softening said member to cause relative transparentizing in the imagewise softened areas due to an agglomeration of the agglomerable layer in the imagewise softened portions of said member.
