    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 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 conformable base sheet (12).
