ABSTRACT:
A continuous tone dry process imaging film includes a solid, high optical density and substantially opaque film of dispersion imaging material deposited on a substrate. Energy is applied to the film of dispersion imaging material, in an amount sufficient to increase the absorbed energy in the material above a certain critical value, to change the same to a substantially fluid state in which the surface tension of the material acts to cause the film, where subject to the applied energy, to disperse and change to a discontinuous film comprising openings and deformed material which are frozen in place following the application of said energy and through which openings light can pass. Means are associated with the film of dispersion imaging material for retarding the change to the discontinuous film, caused by the surface tension, and for controlling the amount of such change in accordance with the intensity of the applied energy above said certain critical value to increase the amount of such change and the area of the openings in the film and decrease the area of the deformed material in the film and, therefore, the optical density in accordance with the intensity of the applied energy above said certain critical value for providing continuous tone imaging.
