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.
这项发明涉及含有N-(苯并咪唑-2-基)芳基羧酰胺的化合物作为紫外线(UV)吸收剂的组合物。这些化合物可用于保护对紫外线敏感的材料,特别是塑料组合物,或其中的成分,如染料、抗微生物剂或增塑剂,免受紫外线的侵害。这些组合物适用于那些仅需要短时间紫外线保护的用途,例如在防晒乳液中,以及需要长时间保护的用途。
