Abstract
A retroreflective article with excellent wide-angle characteristics is provided. Entrance angle characteristics, observation angle characteristics, and rotation angle characteristics are improved. In a retroreflective article, an assembly of multidirectional retroreflective elements is formed, in which either five, or seven or more unit elements are formed so as to share two common base edges forming the triangular base face of the unit elements and a common vertex at which the common base edges intersect, with an adjacent retroreflective element.
