Abstract
Abstract Process and articles for forming line, halftone or continuoustone images which comprises: exposing to actinic radiation in image-receiving manner a solid, positive-acting or negativeacting light-sensitive organic layer having a thickness of at least 0.1 micron, said layer being capable of developing a Rd of 0.2 to 2.2; continuing the exposure to either clear the background of positive-acting light-sensitive layers or to establish a potential Rd of 0.2 to 2.2 with negative-acting light-sensitive organic layers; applying to said layer of organic material, free-flowing powder particles having a diameter, along at least one axis of at least about 0.3 micron but less than 25 times the thickness of said organic layer; while the layer is at a temperature below the melting points of the powder and of the organic layer, physically embedding said powder particles as a monolayer in a stratum at the surface of said light-sensitive layer to yield images having portions varying in density in proportion to the light exposure of each portion; and removing nonembedded particles from said organic layer to develop an image.
