ABSTRACT:
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.
