    摘要: A retroreflective sheeting comprising a substantially transparent face member, an encapsulating member having a front and a back side, the front side of the encapsulating member being sealed by a network of interconnecting bonds to the face member, and retroreflective elements disposed between the face member and the encapsulating member in substantially a monolayer with an air-interface. The encapsulating member comprises a plasticizer-resistant barrier layer which prevents migration of plasticizer therethrough, thereby protecting the aforementioned elements of the sheeting therefrom.
