Beschreibung
Zusammenfassung:	The invention relates to a retroreflective element comprising: a) a core element comprising elastic thermoplastic material and pigment; and b) optical elements coated on the core element, wherein the optical elements cover greater than 50 % of the projected surface area of the core element; wherein the retroreflective element is substantially spherical, disk-shaped or dome-shaped. The invention further relates to a retroreflective element comprising: a) a core element in the form of a pellet or small piece, the core element comprising elastic thermoplastic material; and b) optical elements coated on the core element wherein the optical elements have been treated with a coupling agent. The invention also refers to a retroreflective element comprising: a) a core element in the form of a pellet or small piece comprising elastic thermoplastic material and thermoset resin; and b) optical elements coated on the core element, wherein greater than 50 % of the projected surface area of the core element is covered with optical elements and the core element is capable of undergoing a change of shape upon coating of the optical elements.
