Abstract

L'invention concerne une structure rétroréfléchissante. Structure rétroréfléchissante qui comprend une couche de prismes trianges-rectangles réfléchissant la lumière supportés par une couche de base transparente. Les côtés triangulaires d'extrémité opposés des prismes adjacents sont espacés les uns des autres pour assurer la réflexion interne de la lumière incidente sur la couche de base aux angles d'incidence élevés. Application notamment à la fabrication de revêtements de signalisation.
