Abstract

A reflective article has a structured surface which includes a first and second array of reflective elements. The first array includes elements which have at least a first, second, and third reflecting face arranged to retroreflect incident light in a retroreflected beam. The second array includes elements which have at least a fourth, fifth, and sixth reflecting face arranged to reflect incident light in a second beam at an observation angle greater than 2 degrees. In signing applications, the second beam can be light originating from a stationary light source, the second beam having a direction and beam width suitable for illuminating an observation zone of interest. The retroreflected beam can be light originating from a moving light source such as a vehicle headlamp. Sheeting comprising such an article can be used both where external lighting from a suitable stationary light source is available and where it is not available.
