ABSTRACT:
An imaging member comprising an agglomerable layer on a substrate is agglomerated in image configuration to cause the formation of larger agglomerates in the agglomerated areas which usually produces a relative transparentizing or a color change in the agglomerated areas. This imaging process is followed by contacting the imaged member, usually uniformly, with a solvent for the agglomerable material or a chemical reactant for the agglomerable material to dissolve away agglomerable material in the unagglomerated (which herein includes relatively unagglomerated compared to the agglomerated areas) areas or chemically react with agglomerable material in the unagglomerated areas, respectively at a faster rate than in the agglomerated areas.
