摘要

Retroreflective pavement marking sheet (10) exhibiting improved retroreflective brightness at high incidence angles, the sheet comprising a binder layer (12) having first and second major surfaces (14, 16) and plurality of microspheres (18) partially embedded in and partially protruding from the first major surface, the binder layer comprising a binder material and pigment particles (20), wherein: (1) the binder layer comprises a selected quantity of pigment particles, (2) the microspheres have a selected average index of refraction, (3) the microspheres are present in selected quantity, and in some embodiments the microspheres are embedded to a selected depth. Flat and patterned pavement markings are disclosed.
