ABSTRACT:
A method for producing a photocured image structure, comprising providing a selectively photocured elastomer composition layer having a photocured image portion and an uncured portion, and contacting the selectively photocured elastomer composition layer with a developer comprising a specific ester and optionally a specific alcohol in a specific volume ratio, to wash-out the uncured portion and develop the photocured image portion, thereby obtaining the photocured image structure. By this method, not only is the swelling of the image structure minimized but also the danger of relief breakage and orange peel formation is eliminated, so that an excellent photocured image structure can be produced by a simple operation.
