This invention relates to compositions containing N-(benzimidazol-2-yl)arylcarboxamides as ultraviolet (UV) light absorbers. The compounds are useful to protect UV sensitive materials, particularly plastic compositions, or ingredients thereof such as dyes, anti-microbial agents, or plasticizers from attack by ultraviolet light. The compositions are suitable for those uses where UV protection is required only for short periods of time, for example in sun tan lotions, as well as for uses which require protection for extended periods of time.
本发明涉及含有N-(
苯并咪唑-2-基)芳基羧酰胺的组合物,作为紫外线(UV)吸收剂。这些化合物用于保护UV敏感材料,特别是塑料组合物或其成分,如
染料、抗微
生物剂或
增塑剂,免受紫外线的攻击。这些组合物适用于需要短时间UV保护的用途,例如在日晒油中,以及需要长时间保护的用途。
