  Novel ultraviolet absorbing compounds that are liquid in nature, are low in color (and thus permit use without the concomitant necessity of adding large amounts of other coloring agents to combat such discoloring), and are highly effective in providing protection in wavelength ranges for which previous attempts at low-color ultraviolet absorbers have failed are provided herein. Such compounds provide such excellent, inexpensive, and beneficial protection from ultraviolet exposure within various media, including, but not limited to, clear thermoplastics. The particular compounds are generally polymeric in nature including various chain lengths of polyoxyalkylenes thereon and are liquid in nature to facilitate handling and introduction within the target media. In addition, such ultraviolet absorbers also exhibit extremely low migratory properties thereby providing long-term protective benefits to the target media as well. This invention also concerns the end products, specific broadly defined types of compounds providing such beneficial characteristics, methods of making such low-color compounds, and methods of producing such clear, UV protected end products.

  本发明提供了一种新型的紫外线吸收化合物，其为液态，颜色低（因此可以在不必添加大量其他着色剂的情况下使用，以对抗这种变色），并且在以前尝试使用低色紫外线吸收剂的波长范围内提供高效的保护，这些化合物在各种介质中提供了出色、廉价和有益的紫外线防护，包括但不限于透明热塑性材料。这些特定的化合物通常具有聚氧烷基链的不同长度，并且具有液态性质，以便于在目标介质中进行处理和引入。此外，这些紫外线吸收剂还具有极低的迁移性能，从而为目标介质提供长期的保护效益。本发明还涉及最终产品、提供这种有益特性的特定广义化合物类型、制造这种低色化合物的方法以及生产这种透明的紫外线保护最终产品的方法。
