Abstract (en)

[origin: WO9934241A1] Retroreflective sheeting comprises (a) a flat reflector having at least one primed or unprimed specularly reflective surface, the reflector being selected from the group consisting of metallized paper and metallized polymer; and (b) a dispersion of substantially spherical, substantially transparent microparticles in a light-transmissive, non-pressure-sensitive adhesive binder layer, the dispersion being adjacent to and in direct contact with at least one specularly reflective surface; wherein the microparticles are embedded in the binder layer and are spaced from the reflector by an essentially uncontrolled distance. The sheeting exhibits good retroreflective properties while being cost-effective to manufacture.
