DIRECTION-INDICATING PAVEMENT MARKING HAVING RAISED PROTUBERANCES AND METHOD OF MAKING

Retroreflective article (10), e.g., in the form of a pavement marking, having raised, nonintegral protuberances (16) that exhibit good dry retroreflectivity and recover retroreflectivity quickly after exposure to water. The protuberances may comprise a thermoplastic polymer body and have at least tw...

Beschreibung
Zusammenfassung:	Retroreflective article (10), e.g., in the form of a pavement marking, having raised, nonintegral protuberances (16) that exhibit good dry retroreflectivity and recover retroreflectivity quickly after exposure to water. The protuberances may comprise a thermoplastic polymer body and have at least two different portions. Partially embedded in the protuberances are different sets of optical elements (14) which are in optical association with a light scattering agent. The protuberances are disposed on top of a comformable base sheet (12). Article rétroréfléchissant (10), qui se présente par exemple sous forme de signalisation horizontale et qui comporte des protubérances (16) formées de plusieurs éléments, possédant un bon pouvoir rétroréfléchissant qu'elles retrouvent rapidement après exposition à l'eau. Les protubérances peuvent être constituées d'un corps en polymère thermoplastique et d'au moins deux parties différentes. Différents groupes d'éléments optiques (14) sont partiellement incorporés aux protubérances et associés optiquement à un agent diffusant la lumière. Les protubérances sont disposées sur une couche de base souple (12).
