A method for forming an image comprising the steps of: (a) imagewise exposing a light-sensitive material comprising a support having thereon a light-sensitive layer containing an image-forming material encapsulated in microcapsules comprising a polymer; (b) superposing thereon an image-receiving material comprising a support having thereon an image-receiving layer in contact with the outermost layer of said light-sensitive material; (c) applying sufficient pressure to said superposed materials to imagewise rupture at least part of said microcapsules, to transfer an image from said light-sensitive layer to said image-receiving layer, and to adhere said light-sensitive material and said image-receiving material to form a unitary structure; at least one of said support for said light-sensitive material and said support for said image-receiving material being transparent.

DETAILED DESCRIPTION OF THE INVENTION In the process of this invention, by forming images using a light-sensitive material and an image-receiving material, at least one of these materials having a transparent support, the images formed can be viewed through the light-sensitive material or the image-receiving material without separating the light sensitive material from the image-receiving material after transferring the images.
In addition, the term "light-sensitive material" as used herein means a material for forming latent images by imagewise exposure and a material further capable of forming visible images by applying pressure to the latent images formed.
Furthermore, the process of this invention can be applied to both a system of hardening the exposed portions by polymerization and a system of softening the exposed portions by depolymerizing the exposed portions.
In this specification, while the invention will be explained by reference to the photopolymerization example, the invention is not to be construed as being limited thereto.
In this case, the process of this invention may include a stop of heat development or wet development before applying pressure to the materials containing the latent images formed.
An example of a light-sensitive material for imagewise hardening a copolymerizable compound to form latent images and visualizing the latent images by applying pressure thereto is disclosed in Japanese Patent Application (OPI) No.
179836/82 by Fuji Photo Film Co.
, Ltd.
The light-sensitive material is composed of a support having thereon synthetic high molecular resin capsules containing a vinyl compound, a photopolymerization initiator, and a coloring material precursor.
Also, a light sensitive material containing silver halide, which is imagewise exposed, heat-developed to develop silver halide and at the same time to harden a polymerizable compound corresponding to the development, and then applying pressure to obtain visible images, is disclosed in Japanese Patent Application (OPI) No
