ALL-WEATHER TYPE SHEET MATERIAL FOR MARKING ROAD SURFACE

摘要

In an all-weather type pavement marking sheet material, glass microspheres having refractive index of 1.5 - 1.9 (A) and glass microspheres having refractive index of 2.0 - 2.4 (B) are embedded mixedly and at least partially in a portion of a base sheet (1) made of rubber, synthetic resin or the like. This portion (S) is formed at intervals in the longitudinal direction of the base sheet or continuously in the longitudinal direction of the base sheet in a part of the base sheet as viewed in the transverse direction of the base sheet. The pavement marking sheet material has an excellent visibility during night and particularly when it is raining.
