RETROREFLECTIVE SHEETING AND METHODS FOR MAKING SAME

摘要

A relatively flexible retroreflective laminate sheet construction includes a thermoplastic web (26) a light-receiving and transmitting front side (28) and a reverse side (30) co-extensive with the front side (26), a retroreflective pattern being formed on the reverse side (30). A layer (34) is deposited on the reverse side (30) to cover selected portions of the formed retroreflective pattern with the remaining portions of the formed pattern devoid of the granular material. A layer (32) of back coating material is deposited on the reverse side to overlay the granular material (34). The back coating material contacts the remaining portions of the formed pattern and is fixedly secured thereto, thereby encapsulating the granular material between the reverse side (30) and the back coating layer (32).
