<p>A transparent or translucent sheet comprising a substrate having on the outer surface facing the atmosphere a coating composition having a hydroxy-functional silicone modified acrylate polymer additive in sufficient amount to allow ease of removing solid particles (dirt) and/or liquids on the surface by reducing the adhesion of such particles and/or liquids to the substrate. The coating composition used for manufacturing the sheet also has in combination therewith an ultra violet absorber along with a polymer matrix such as an acrylate polymer and a solvent such as methoxypropanol and eventually a mar resistant coating. The amount of silicone modifier acrylate polymer may range from about 0.5 to about 6.0 weight % based on the total weight of the coating composition. A preferred ultra violet absorber is a polybenzoylresorcinol. The preferred substrate is a transparent aromatic polycarbonate resin sheet or multiwall polycarbonate at least two polycarbonate sheets having interdisposed there between and joining said sheets a structure of essentially any configuration.</p> |
