ABSTRACT:
Method of forming a color image of a graphic object pattern directly on a support medium. A water-soluble photosensitive stencil material is coated on the support and exposed imagewise to actinic radiation. The exposed photosensitive stencil material is developed to remove the water-soluble, unexposed stencil material. A layer of water-permeable, water-insoluble color medium is applied. The color medium is treated with water or an aqueous solution to permeate the color medium and soften the stencil material which is removed by mechanical action. Alternatively, a water-insoluble photosensitive stencil material, which becomes water-soluble on exposure to actinic radiation, may be coated on the support.
