    Abstract: The invention relates to articles comprising a sheeting having a microstructured surface that reflects light in a moirnull-like pattern. The invention further relates to methods of making a master and replicas thereof including tooling that results in sheeting having such pattern. A preferred method comprises forming V-shaped grooves in a substrate (e.g. metal plate) wherein the intersections of three grooves form cube-corner elements. The cube-corner elements are formed in such a manner that adjacent parallel grooves have substantially the same groove spacing and groove depth throughout the array. The master as well as corresponding tooling and sheeting preferably have a groove spacing within the range of about 0.0005 inches (0.0127 mm) to about 0.007 inches (0.1778 mm) throughout the array and more preferably a groove spacing of less than about 0.004 inches (0.1016 mm).

    Abstract: The invention relates to methods of making a master and replicas thereof including tooling and retroreflective sheeting. The invention further relates to the corresponding master, tooling and in particular retroreflective sheeting. The method comprises forming V-shaped grooves in a substrate (e.g. metal plate) wherein the intersections of three grooves form cube-corner elements. The cube-comer elements are substantially the same size throughout the array. The master as well as corresponding tooling and sheeting preferably have an average groove spacing within the range of about 0.0005 inches (0.0127 mm) to about 0.007 inches (0.1778 mm) throughout the array and more preferably an average groove spacing of less than about 0.004 inches (0.1016 mm).

    Abstract: A retroreflective article 10 has a body portion 14 and a multitude of cube-corner elements 12 that project from a rear side 20 of the body portion 14. The body portion 14 includes a body layer 18 that contains a light-transmissible polymeric material having an elastic modulus less than 7null108 pascals. The cube-corner elements 12 contain a light transmissible polymeric material having an elastic modulus greater than 16null108 pascals. A retroreflective article of this construction can be highly flexed while maintaining good retroreflective performance.

    Abstract: A process for making molds for retroreflective sheeting and like articles includes making a substrate having a structured surface of geometric structures such as cube corner elements. The structured surface is in one embodiment partially replicated from a previous generation structured surface, and partially machined in the substrate. At least one of the faces of the structured surface is a compound face that has one machined portion and one non-machined portion, such as a replicated portion. The process can be used to manufacture substrates with desirable geometry cube corner elements, such as cube corner elements having a hexagonal outline in plan view, without requiring the use of pin bundling techniques or laminae. The process can also be used to manufacture articles having cube corner elements in which at least one face of the cube corner element has two constituent faces disposed on opposed sides of a transition line that is nonparallel to a nondihedral edge of such cube corner element.

    Abstract: Retroreflective sheeting includes a body layer having a structured surface with recessed faces forming cube corner cavities. A reflective film is disposed at least on the recessed faces, and a fill material fills the cube corner cavities. The fill material comprises radiation-curable materials, adhesives, or both, and preferably transparent radiation-curable pressure-sensitive adhesives. The fill material preferably forms a continuous layer covering both the recessed faces and upper portions of the structured surface. A transparent cover layer preferably contacts the fill material layer.
