Multi-color image-forming method with microcapsule positive diazotype color image formation and positive light-solubilizing color image formation

Claim 1

A multi-color image-forming method comprising the steps of: (a) using a positive image, imagewise-exposing with light, a light-sensitive heat-sensitive material comprising a support having provided thereon, a recording layer comprising a diazonium compound and a coupling component capable of forming a dye upon coupling with the diazonium compound, wherein at least one of the diazonium compound and the coupling component are present in microcapsules, and developing said light-sensitive heat-sensitive material to form a positive color image of said positive image; (b) using a positive image, imagewise-exposing with light, a light-solubilizing color image-forming material comprising a substantially transparent support having provided thereon a light-sensitive layer comprising a light-solubilizing image-forming material and a polymeric binder, and a coloring layer comprising a coloring material, and developing said light-solubilizing color image-forming material to form a positive color image of said positive image; (c) superimposing the resulting light-solubilizing color image-forming material of step (b) on the resulting light-sensitive heat-sensitive recording material of step (a) to provide a superimposed material (d) heat-pressing the resulting superimposed material of Step (c).
