ABSTRACT:
The invention relates to a vinyl polymer composition suitable for outdoor use in the sunlight. The heat buildup in articles made from the composition is lowered without changing the ultraviolet protection or the color of the articles. This is accomplished by employing in the composition a black infrared reflecting pigment, such as a mixture of Cr.sub.2 O.sub.3 and Fe.sub.2 O.sub.3, and other infrared reflecting pigments.
