Abstract: Process of manufacturing a metal pattern provided with at least one aperture through which light may be transmitted to project an image on a surface in the shape of the aperture, may include the steps of providing at least a first member extending upwardly from the top surface of a substrate in the shape of the aperture and where the aperture is to be formed in the metal pattern, applying a layer of electrically conductive material to the top surface of the substrate at least around the first member, forming a layer of metal on the layer of electrically conductive material, and peeling the substrate, the upwardly extending first member and the layer of electrically conductive material away from the layer of metal to provide the aperture in the layer of metal and to thereby form the pattern.

Abstract: Retroreflective material, and articles of manufacture made therefrom and process of making the same, wherein the color of an underlying colored material, such as colored thermoplastic film, is visible, in visible light, through the portion of an overlying substantially clear material, such as clear thermoplastic film, which clear material is sealed such as by heat sealing, to the colored material, the sealing obliterates or removes the retroreflective surface intermediate the materials at the place of sealing making the color of the underlying colored material visible through the sealed portion; the retroreflectivity of the remaining intermediate retroreflective surface is undiminished. Upon the entire periphery of the overlying and underlying layers of material being sealed, the remaining retroreflective surface intermediate the layers is completely sealed against contamination and the retroreflectivity of the remaining intermediate surface is undiminished.
