Abstract (en)

A high-brightness all-weather type pavement marking sheet material (A) is composed of a reflex-reflecting sheet (1) and a base sheet (2). The reflex-reflecting sheet (1) comprises a layer of glass microspheres (4) of a relatively large diameter which are at least partially exposed in air and bonded to one another by a transparent resin, a layer of glass microshperes (5) of a relatively small diameter which are buried and fixed in a transparent resin layer behind the glass microspheres (4) of a large diameter with an interval between the glass microspheres (4) of a large diameter and the glass microspheres (5) of a small diameter, and a reflecting layer consisting of a metallized film or the like material provided behind the glass microspheres (5) of a small diameter. The base sheet (2) is made of rubber or synthetic resin and is bonded to the lower surface of the reflex-reflecting sheet (1). The pavement marking sheet material (A) has an excellent brightness in reflection during night and particularly when it is raining.
