Abstract: An imaging system wherein a migration-type imaging member comprising a softenable layer containing agglomerable migration marking material is provided, and the member is exposed to an image pattern of electromagnetic radiation of sufficient energy to cause a simultaneous imagewise migration at least in depth in the softenable layer and agglomeration of the agglomerable migration marking material in the imagewise exposed areas of the imaging member. In another embodiment, a microscopically discontinuous layer of imaging material on a stable substrate is agglomeration or evaporation imaged by the inventive system.

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.

Abstract: An imaging member comprising an agglomerable layer on and not embedded in a substrate is agglomerated in image configuration to cause relative transparentizing or a color change and the formation of larger agglomerates in the agglomerated areas. This imaging process is followed by removal of the agglomerates from the agglomerated areas.
