Retroreflective sheet

Abstract

A retroreflective sheet 9 of the present invention includes; a surface layer 1; a glass bead holding layer 5 containing glass beads 3 that are located randomly as viewed cross-sectionally; and a metal reflective layer 4 on a back surface side of the glass bead holding layer 5. The surface layer 1 is a vinyl chloride resin layer. The retroreflective sheet further includes, between the vinyl chloride resin layer and the glass bead holding layer, a barrier layer 2 for preventing deterioration of the metal reflective layer. The barrier layer 2 is preferably an alkyd-melamine resin layer. Thereby, it is possible to provide a retroreflective sheet that can prevent the degradation of, e.g., the reflective function of the metal reflective layer on the back surface side of the glass bead holding layer and thus maintaining high weather resistance and wide-angle reflectivity, and that can exhibit high surface printability.
