Patent number: 7772415Abstract: Infrared (IR) radiation absorbing compounds of metal or metalloids with ligands are beneficial for many applications. Schiff base biquinone (SBB) ligands surrounding a metal or metalloid center may be used for laser welding applications, as one example, wherein effective infared radiation absorption and heat resistance are required. These compounds may be known as Schiff base biquinone metal complexes (SBBC's). The compositions and methods of this invention provide examples of many different NIR absorbing compounds that exhibit high NIR absorbing strength, good thermal stability, and relatively low visible color. The IR absorbing compounds may employ one or more of the following elements: Si, Zr, Bi, Sb, Ce, Cs, K, Mo.Type: GrantFiled: June 12, 2006Date of Patent: August 10, 2010Assignee: Milliken & CompanyInventors: Keith A. Keller, Daniel M. Connor, John G. Lever

Patent number: 7097789Abstract: Novel thermoplastic articles that contain 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 any discoloring within clear, colorless applications), are substantially non-migratory from target resins, and are highly effective in providing protection in wavelength ranges for which previous attempts at low-color ultraviolet absorbers have failed are provided. In effect, the inventive thermoplastic articles, provide excellent protection for certain vitamins, flavorings, and colorants, for example, from ultraviolet degradation, particularly above the 370 nm wavelength that is typically the high end of protection for clear thermoplastics having low migratory, colorless UV absorbers therein.Type: GrantFiled: October 23, 2002Date of Patent: August 29, 2006Assignee: Milliken & CompanyInventors: Daniel M. Connor, Sean M. Bernhardt

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: 6635350Abstract: Red colorants comprising a chromophore having at least one poly(oxyalkylene) chain attached to the 1-position, as well as at least one poly(oxyalkylene) chain attached to either the 5-position or the 8-position of an anthraquinone backbone are provided. Such colorants exhibit excellent base stability, effective colorations, excellent low extraction rates, and high lightfastness levels, particularly when incorporated within certain media and/or on the surface of certain substrates, particularly polyesters. The poly(oxyalkylene) chains also increase the solubility in different solvents or resins thereby permitting the introduction of such excellent coloring chromophores within diverse media and/or diverse substrates as well as provides a liquid colorant which facilitates handling. Compositions and articles comprising such colorants are provided as well as methods for producing such inventive colorants are also provided.Type: GrantFiled: October 16, 2001Date of Patent: October 21, 2003Assignee: Milliken & CompanyInventors: Daniel M.
