Patent ID: 7587845

Claim:
A nautical sign having reflective and luminescent qualities which comprises: a front rigid sheet having an upper surface and a lower surface; a first retroreflective layer comprising a first plurality of reflective disks having an upper surface and a lower surface, the first retroreflective layer is positioned such that the upper surface of the first plurality of reflective disks of the first retroreflective layer contacts the lower surface of the front rigid sheet; a luminescent layer comprising a photoluminescent film having an upper surface and a lower surface, wherein the photoluminescent film absorbs photons from a light source and remains glowing when the light source is removed, the luminescent layer is positioned such that the upper surface of the photoluminescent film contacts the lower surface of the first plurality of reflective disks of the first retroreflective layer; a second retroreflective layer comprising a second plurality of reflective disks having an upper surface and a lower surface, the second retroreflective layer is positioned such that the upper surface of the second plurality of reflective disks of the second retroreflective layer contacts the lower surface of the photoluminescent film; and a back rigid sheet having an upper surface and a lower surface, the back rigid sheet is positioned such that the upper surface of the back rigid sheet contacts the lower surface of the second plurality of reflective disks of the second retroreflective layer.
