摘要：
A retroreflective sheeting (10) comprising a cube layer (20) having a front light-receiving surface (30) and a rear retroreflecting surface (32), and a metallic layer (22) covering the rear retroreflecting surface (32). The rear surface (32) comprises an array of retroreflective elements (34) and diffusing patches (36) within such array (without retroreflective elements (34)). The metallic layer (22) covers the retroreflective elements (34) and the diffusing patches (36), whereby diffusing patches (36) scatter incoming light increasing daytime brightness to a desired level.
