A RETROREFLECTIVE SHEETING AND A METHOD FOR MAKING THE SAME

Abstract The invention provides a retroreflective sheeting and a method of making the same. The retroreflective sheet comprises a support layer, at least the back stratum of which is a vulcanizable or curable elastomer. A monolayer of retroreflective elements are partially embedded in and protruding form said support layer. At least some of said retroreflective elements are oriented such that the front surfaces of said retroreflective elements protrude from said support layer permitting light incident thereto to be retroreflected by said retroreflective elements. A dimensionally stable premask is releasably adhered to the front surfaces of said retroreflective elements.
