PROBLEM TO BE SOLVED: To provide a retroreflective material which exhibits high color saturation to wide-angle incident light, can change color hues of reflected light according to an incident angle of the incident light, and suppresses color unevenness of the reflected light.SOLUTION: In an open type retroreflective material, a transparent resin layer and a reflective layer formed of a transparent metal thin film are laminated between transparent microspheres and a fixed resin layer and a layer thickness of the transparent resin layer is set so as to satisfy a predetermined condition, and thereby the retroreflective material exhibits high color saturation to wide-angle incident light, can change color hues of reflected light according to an incident angle of the incident light, and can suppress color unevenness.SELECTED DRAWING: None |
