Multi-color reproductions

Abstract

Abstract THE METHOD OF FORMING A MULTICOLOR REPRODUCTION WHICH COMPRISES: COATING A SUBSTRATE BEARING A FIRST COLOR FUSED IN IMAGE-WISE CONFIGURATION TO SAID SUBSTRATE WITH A SOLID, LIGHT-SENSITIVE ORGANIC LAYER HAVING A THICKNESS OF AT LEAST 0.1 MICRON WHILE MAINTAINING SAID FIRST COLOR IN ITS IMAGE-WISE CONFIGURATION, SAID LIGHT-SENSITIVE ORGANIC LAYER BEING CAPABLE OF DEVELOPING A RD OF 0.2 TO 2.2; EXPOSING SAID LIGHT-SENSITIVE ORGANIC LAYER TO ACTINIC RADIATION IN IMAGE-RECEIVING MANNER TO ESTABLISH A POTENTIAL RD OF 0.2 TO 2.2; APPLYING TO SAID LAYER OF ORGANIC MATERIAL, FREE FLOWING POWDER PARTICLES OF A SECOND COLOR 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 A THE SURFACE OF SAID LIGHT-SENSITIVE LAYER TO YIELD AN IMAGE HAVING PORTIONS VARYING IN DENSITY IN PROPORTION TO THE EXPOSURE OF EACH PORTION; AND REMOVING NON-EMBEDDED PARTICLES FROM SAID ORGANIC LAYER TO DEVELOP A MULTICOLOR REPRODUCTION.
