摘要： The present invention is directed to providing a security sticker which is hard to be counterfeited, cannot be reused if being released and includes a printed image that is stable over a long period of time, and is directed to providing a method for manufacturing the same. The security sticker of the present invention includes: a surface resin layer (A)1 that has a weak affinity with a sublimable dye and allows the dye to penetrate; a print layer (B)2 that contains a low-molecular-weight compound with a molecular weight of 1300 or less in an amount of 0% to 20 wt % inclusive, has an affinity with the dye, and includes an image formed in a thickness direction of the layer by the dye; a self-destructive film layer (C1)3; and a pressure-sensitive adhesive layer (D1)4 in this order, wherein the self-destructive film layer (C1) includes a dye migration preventive resin layer (E) for preventing migration of the dye and a self-destructive layer (F), and the dye migration preventive resin layer (E) is a resin layer containing a certain kind of a vinyl resin as a main component, or a certain kind of a biaxially stretched film.

摘要： The hue variable retroreflective sheet of the present invention includes: a surface layer (1) composed of at least one layer; and a plurality of retroreflective elements (3, 4, 5) that are positioned beneath the surface layer, wherein the retroreflective elements (3, 4, 5) retroreflect incident light toward a light source direction, at least one layer of the surface layer (1) is an optical coherent layer that changes in color depending on a point of view, and in which an optical coherent coloring material with a core material having a surface that is covered with one or more substantially transparent coating layer is dispersed, and mirror-reflects the incident light toward a direction opposite to the light source side, at least one layer of the retroreflective sheet is a colored layer containing a coloring material that colors retroreflected light, and the retroreflected light and the mirror-reflected light provide different hues. Thereby, the present invention provides the hue variable retroreflective sheet that provides hues in two or more different colors by the interference of light in daylight, provides retroreflected light in color with a hue that is different from the hue in the daylight when light is projected at night, and provides a color that has still different from the hue of the retroreflected light on the other side of an incident light beam.

摘要： The retroreflective sheet of the present invention comprises a surface layer (1) including at least one layer, a focusing layer (2) containing glass spheres (3), and a metal reflective layer (4) on the back side of the focusing layer (2), wherein the glass spheres (3) are disposed at random locations in the thickness direction of the focusing layer (2). The external illumination system of the present invention comprises a sign having a sign face including the above-mentioned retroreflective sheet, and an external illumination source, and the distance from the illumination source to the sign face is within a range of at least 1 m and no more than 100 m. The present invention thereby provides a retroreflective sheet and an external illumination system with which wide-angle reflective performance with a wider incidence angle and observation angle can be ensured.
