    Abstract: A cube-corner retroreflective sheeting (60) includes an array of cube-corner elements (30) that are defined by three sets of intersecting parallel grooves (45, 46, 47). The cube-corner elements (30) are arranged in the array such that the sheeting (60) glitters when exposed to light. The glitter is in the form of many discrete points of light (68) that tend to blink on and off when viewed by the nacked eye. The array may be configured such that a dihedral angle alpha varies between adjacent cube faces (31) of adjacent cube-corner elements (30) in each groove in one of the groove sets (45, 46 or 47) and such that base planes (36) are not parallel to each other when the sheeting (60) is laid flat. Preferably, the dihedral angle alpha between faces (31) of adjacent cube-corner elements (30) varies in essentially all of the grooves such that the cube-corner elements are randomly tilted throughout the array. The sheeting glitters very well under daytime viewing conditions and also to some extent under nighttime or retroreflective conditions. The glittering effect can enhance the sheeting's conspicuity, and hence highlight a person's presence to give them improved safety and security.

    Abstract: A glittering non-reflective sheeting (60) includes an array of cube-corner elements (30) that are arranged in the array such that the sheeting glitters when light is incident thereon. The glitter is in the form of many discrete points of light (68) that tend to blink off and on. The array may be configured such that a dihedral angle alpha varies between adjacent cube faces (31) of adjacent cube-corner elements (30) in each groove in one of the groove sets (45, 46, or 47) and such that the base planes (36) are not parallel to each other when the sheeting (60) is laid flat. Preferably, the dihedral angle alpha between faces (31) of adjacent cube-corner elements (30) varies in essentially all of the grooves such that the cube-corner elements are randomly tilted throughout the array. The glitter can make the sheeting very useful for aesthetic or decorative applications.

    Abstract: A retroreflective article comprising an ultra-flexible structured retroreflective sheeting having a front surface and a back surface, the sheeting retroreflecting light entering through the front surface, wherein the sheeting comprises an overlay film, a two-dimensional array of substantially independent structured elements, the structured elements bonded to the overlay film, and a sealing film forming the back surface of the sheeting and bonded to the overlay film between the structured elements; a plurality of indentations in the sealing film; and a seal coat located on the sealing film, wherein the seal coat at least partially fills the indentations in the sealing film.

    Abstract: Retroreflective sheeting and articles are formed in which the size of the retroreflective and non-retroreflective surfaces may be varied across an array of microprisms. This is accomplished by varying the location of the reflective coating applied to the microprism side facets, such that, some prism side facets are completely coated with reflective material while others are coated only at the apex area; and still others are coated with a non-reflective coating, such as, a colored adhesive.
