Abstract
Abstract An image-forming method which comprises: imagewise exposing a light-sensitive material comprising a light-sensitive layer provided on a support wherein the light-sensitive layer contains silver halide, a reducing agent and a mixture of at least two polymerizable compounds to form a latent image of the silver halide; simultaneously or thereafter developing the light-sensitive material to polymerize the mixture of the polymerizable compounds within the area where the latent image of the silver halide has been formed; and pressing the light-sensitive material on an image-receiving material to transfer the unpolymerized mixture of the polymerizable compounds to the image-receiving material.
