ABSTRACT:
A retroreflective article and a method for making same are taught. The retroreflective article comprises transparent microspheres and both specular and diffuse reflective pigments dispersed in a binder layer. The utilization of both types of pigments results in improved retroreflectivity over a greater range of entrance angles than if only one or the other pigment alone were used.
