Conformable cube corner retroreflective sheeting

Abstract

Conformable cube corner retroreflective sheetings comprising a plurality of discrete cube corner segments which are conformably bonded together, each cube corner segment comprising a plastic body portion having a substantially planar front major surface and at least one minute cube corner retroreflective element projecting rearwardly from the body portion and defining a cube corner point side of the cube corner segment. The peripheries of the cube corner segments can be defined by a plurality of separations extending from the cube corner point sides to the front major surfaces, the separations being disposed between adjacent cube corner segments. Adjacent cube corner segments are conformably bonded together in the sense that they are either: (1) separated by a gap of less than about 1 millimeter and bonded together through a conformable carrier layer; or (2) separated by a gap which is substantially filled with a conformable resin that bonds the side walls of adjacent cube corner segments together. Alternatively, a conformable cube corner retroreflective sheeting can comprise a plurality of connecting bridges disposed between adjacent cube corner segments, the connecting bridges being at least one of fractured and frangible, and spanning grooves which extend vertically from the cube corner point sides toward the front major surfaces and terminate at the connecting bridges. Also, methods for making such conformable sheetings.
