  The novel transparent polyolefin or polyamide article disclosed is stabilized against the effects of light, oxygen, heat and agressive chemicals by addition of 0.005-0.30% by weight the polymeric substrate of a hydroxyphenyl triazine UV absorber, and is characterized by its thickness between 1 and 500 μm. Preferred polyolefin articles thus stabilized are agricultural films containing as further stabilizer a sterically hindered amine. The novel compositions act as selective UV filter especially useful in agriculture.

  所披露的透明聚烯烃或聚酰胺材料经过添加0.005-0.30%重量的羟基苯基三嗪紫外线吸收剂进行稳定，以抵抗光、氧、热和侵蚀性化学物质的影响，并以其厚度在1至500μm之间的特点而闻名。因此，优选稳定的聚烯烃材料是农业薄膜，其中还包含了一个立体阻碍胺作为进一步的稳定剂。这种新型组合物作为选择性紫外线过滤器，在农业中特别有用。
