Abstract
The invention described in the specification relates to latent image printing and developing systems and to substrates containing latent images. High quality latent images are prepared by a printing method which deposits a layer containing organic-based dye particles and organic-based developer particles, each having a particle size of from about 2 to about 6 microns, on a substrate. The image is then developed by contacting the substantially invisible image of dye and developer particles with an oxygenated solvent from an imaging device. Multicolor, vivid images are obtained as a result of the image printing and developing system of the invention.
