A color image forming process wherein images are formed by reaction of cyan, magenta and yellow color precursors with a developer material, the reaction is image-wise controlled by image-wise exposure of a photosensitive composition encapsulated in pressure rupturable capsules, image-wise exposure of the photosensitive composition and rupture of the capsules releases the color precursor for patterned reaction with the developer material.

An imaging process employing: a first imaging sheet comprising a support and a coating composition adhered to one surface of said support, said coating composition including a first color precursor selected from a cyan, magenta and yellow color precursor, and a radiation curable photosensitive composition, wherein at least said photosensitive composition is encapsulated in pressure rupturable capsules and said first color precursor is soluble in said radiation curable photosensitive composition or a solvent for said first color precursor is encapsulated with said radiation curable photosensitive composition, a second imaging sheet comprising a support and a coating composition adhered to one surface of said support, said coating composition comprising a second color precursor selected from a cyan, magenta and yellow color precursor other than said first color precursor, and a radiation curable-photosensitive composition, wherein at least said photosensitive composition is encapsulated in pressure rupturable capsules and said second color precursor is soluble in said radiation curable photosensitive composition or a solvent for said second color precursor is encapsulated with said radiation curable photosensitive composition, a third imaging sheet comprising a support and a coating composition adhered to one surface of said support, said coating composition comprising a third color precursor selected from a cyan, magenta and yellow color precursor other than said first and second color precursors, and a radiation curable photosensitive composition, wherein at least said photosensitive composition is encapsulated in pressure rupturable capsules and said third color precursor is soluble in said radiation curable photosensitive composition or a solvent for said third color precursor is encapsulated with said radiation curable photosensitive composition, a developer sheet comprising a support coated on one surface with a dry material capable of reacting with said color precursors and providing an image, comprising: (a) resolving a multi-color image into its red, green, and blue images, (b) translating, individually, each of said red, green and blue images into a radiation which is actinic with respect to the radiation curable photosensitive composition on said imaging sheet bearing the color precursor compliment of said image, (c) image-wise exposing said first imaging sheet to said radiation translated from said red, green or blue image which is complimentary to said first color precursor, to form exposed and unexposed areas in said first sheet, (d) image-wise exposing said second imaging sheet to said radiation translated from said red, green or blue image which is complimentary to said second color precursor to form exposed and unexposed areas in said second sheet, (e) image-wise exposing said third imaging sheet to said radiation translated from said red, green or blue image which is complimentary to said third color precursor to form exposed and unexposed areas in said third sheet, (f) rupturing the capsules in at least the unexposed areas of said first imaging sheet, (g) rupturing the capsules in at least the unexposed areas of said second imaging sheet, (h) rupturing the capsules in at least the unexposed areas of said third image sheet, (i) transferring said first color precursor from the unexposed areas of said first sheet to said developer sheet to form an image, (j) transferring said second color precursor from the unexposed areas of said second sheet to said developer sheet to form an image and (k) transferring said third color precursor from the unexposed areas of said third imaging sheet to said developer sheet to form an image, and thereby obtaining a full color image.
