METHOD OF MAKING GLITTERING CUBE-CORNER RETROREFLECTIVE SHEETING

摘要

A method of making a glittering cube-corner sheeting, which method comprises: a) providing a first retroreflective sheeting that includes an array of cubecorner elements arranged in a repeating pattern; and b) exposing the first retroreflective sheeting to heat, pressure, or a combination thereof to produce a second retroreflective sheeting that comprises an array of cubecorner elements that are randomly tilted, the cube-corner elements becoming randomly tilted from the heat, pressure or the combination thereof other than through securing a seal film to the array that is arranged in the repeating pattern; or which method may comprise: forming a cube-corner sheeting from a mold that has a structured surface that includes a multiplicity of cube-corner elements, the cube-corner elements each including a base plane and three faces, the cube-corner elements being arranged such that the base planes do not reside in the same plane when the sheeting is laid flat.
