Retroreflective sheet for security and method for manufacturing the same

Abstract

The present invention is directed to providing a retroreflective sheet for security that is difficult to be counterfeited, cannot be reused if once released, includes a printed image that can be identified visually regardless of an object to be attached such as a colored glass and also can be identified visually clearly even in the night time, and is directed to providing a method for manufacturing the same. The retroreflective sheet for security of the present invention includes: a surface layer 1; a binder layer 2; high-refractive-index glass beads 3; a print resin layer 4; a focusing layer 5; a metal layer 6; and a pressure-sensitive adhesive layer 7 in this order, wherein the print resin layer 4 forms a mark, the high-refractive-index glass beads 3 are disposed in the binder layer 2, a position for disposing the high-refractive-index glass beads 3 does not coincide with a position of the print resin layer 4, when being observed from the surface layer 1 side in a thickness direction of the retroreflective sheet for security, and the print resin layer 4 is made of a composition containing a room temperature curing resin as a main component.
