Zusammenfassung:	The disclosed retroreflective element includes a highly durable core with an ionic copolymer and a plurality of beads. These disclosed retroreflective properties remain intact even after continued application of external forces and stresses. Further, the ionic copolymer allows for beads to be loaded into the ionic copolymer of the core, securely disposed around the perimeter of the core, or both. La présente invention concerne un élément rétroréfléchissant qui comprend un noyau hautement durable comprenant un copolymère ionique et une pluralité de billes. Ces propriétés rétroréfléchissantes selon l'invention restent intactes même après une application continue de forces extérieures et de contraintes. En outre, le copolymère ionique permet aux billes d'être chargées dans le copolymère ionique du noyau, disposées solidement autour du périmètre du noyau, ou les deux.
