PAVEMENT MARKING HAVING RAISED PROTUBERANCES AND METHOD OF MAKING

摘要

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 protuberance comprise a thermoplastic polymer body. Partially embedded in the protuberance are optical elements (14) which are in optical association with a light scattering agent. The protuberance is disposed on top of a conformable base sheet (12).
