Abstract
Abstract A method is described for forming an image by transferring an image layer formed on a transferable light-sensitive material to an image-receiving sheet, and then further transferring the image to a permanent support, wherein the image-receiving sheet comprises a support, a first layer on the support, said first layer being made of a first organic polymeric substance, and a second layer on the first layer, said second layer being made of a second organic polymeric substance, wherein in peeling apart the image-receiving sheet from the transferable light-sensitive material, P.sub.1, P.sub.2, P.sub.3 >P.sub.4 wherein P 1 is an adhesion force between the support and the first layer, P 2 is an adhesion force between the first and second layers, P 3 is an adhesion force between the second layer and the image layer, and P 4 is an adhesion force between the transferable image layer and the support of the image, and in re-transferring the image layer to the permanent support and peeling apart the image-receiving sheet from the permanent support, P.sub.5, P.sub.1, P.sub.2 >P.sub.3, or P.sub.5, P.sub.1, P.sub.3 >P.sub.2 wherein P 5 is an adhesion force between the permanent support and the transferable image layer.
