ABSTRACT:
Process for formation of white opaque image in the toned areas of a photopolymer composition which comprises a leachable monomer, photoinitiator, organic polymer binder and optionally a plasticizer wherein the toned image areas are treated with a leaching solution, e.g., mixtures of organic solvents or mixtures of water and organic solvents; washing the treated areas, e.g., with water; and drying at a temperature up to 70.degree. C., e.g., with hot air dryer. The process is useful for the preparation of overlay exhibits and direct positive image for microfilm.
