  • Patent number: 5397683
    Abstract: A photochemical method of making a tactile design comprises the steps of exposing to light a selected portion of photo-sensitive layer-supported by a substrate; applying a decorative coating to the photo-sensitive layer; applying a photo-sensitive emulsion over the decorative coating; exposing to light the same selected portion of the photo-sensitive emulsion; and removing the photo-sensitive emulsion, the decorative coating, and the photo-sensitive layer from the non-selected portions. The tactile design comprises a layer of photo-sensitive material fixedly attached to a selected portion of a substrate wherein the layer has been exposed to light and the layer projects away from the surface of the substrate a sufficient distance to be sensitive to the touch. At least one decorative coating is fixedly attached to the photo-sensitive layer.
