    • A method for forming images on plain paper is disclosed, comprising the steps of: image-wise exposing an imaging sheet, said imaging sheet comprising a support having a layer of photosensitive microcapsules on the surface thereof, said microcapsules containing a photohardenable or photosoftenable composition including a photoinitiator, and a color precursor; assembling said image-wise exposed imaging sheet with a sheet of plain paper; subjecting said assembly of said imaging sheet and said plain paper to a uniform rupturing force to cause said photosensitive microcapsules to rupture and transfer an image-wise pattern of said color precursor to said plain paper thereby forming a latent image thereon; separating said imaging sheet from said plain paper; assembling said plain paper bearing said latent image with a developer-donor sheet comprising a support having a layer of a developer on the surface thereof to form a second assembly; subjecting said second assembly to a uniform force to transfer said developer to said plain paper bearing said latent image whereupon said developer reacts with said color precursor to form a visible image.
    • 公开了一种在普通纸上形成图像的方法,包括以下步骤:成像片曝光成像片,所述成像片包括其表面上具有感光性微胶囊层的支持体,所述微胶囊含有可光硬化或可光软化的组合物,包括 光引发剂和彩色前体; 用一张普通纸组装所述成像曝光的成像片; 使所述成像片和所述普通纸的组件经受均匀的破裂力,以使所述感光微胶囊破裂并将所述彩色前体的成像图案转移到所述普通纸,从而在其上形成潜像; 将所述成像片与所述普通纸分离; 用显影剂供体片组装所述潜影的所述普通纸,所述显影剂供体片包括其表面上具有显影剂层的支撑体,以形成第二组件; 使所述第二组件经受均匀的力以将所述显影剂转移到所述潜在图像上,所述显影剂与所述彩色前体反应形成可见图像。
