Beschreibung
Zusammenfassung:	Optical structures and sheeting that include polyurea and method for forming same are proposed in accordance with aspects of the present invention. One and two-component layers can be used to form the optical structures. The optical structures can include microstructures formed from polyurea. The sheeting can include at least one of cube-corner prisms, open-faced cube-corner prisms, linear prisms, lenticular lenses, moth-eye structures, lenses, Fresnel lens arrays, lenses, and fish-eye lens arrays. Des aspects de la présente invention concernent une feuille et des structures optiques à base de polyurée, ainsi qu'un procédé de production de cette feuille et de ces structures. Lesdites structures optiques peuvent être formées au moyen de couches à un et à deux composants. Ces structures optiques peuvent comprendre des microstructures composées de polyurée. La feuille peut comprendre au moins un des éléments suivants : prismes en coin de cube, prismes en coin de cube à face ouverte, prismes linéaires, lentilles lenticulaires, structures de type moth-eye, lentilles, mosaïque de lentilles de Fresnel, mini-lentilles et mosaïque de lentilles de type fish-eye.
