Patent number: 7014797Abstract: Novel ultraviolet absorbing compounds that are liquid in nature, are extremely low in color 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.Type: GrantFiled: December 31, 2002Date of Patent: March 21, 2006Assignee: Milliken & CompanyInventors: Todd D. Danielson, Xiaodong E. Zhao, Mary E. Mason, Daniel M. Connor, Eric B. Stephens, Jason D. Sprinkle, Jusong Xia

Patent number: 6891058Abstract: Novel ultraviolet absorbing compounds that are liquid in nature, are extremely 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.Type: GrantFiled: January 3, 2003Date of Patent: May 10, 2005Assignee: Milliken & CompanyInventors: Xiaodong E.
