摘要:
Disclosed are novel ultraviolet-absorbing compounds produced by two embodiments. By a first embodiment, the ultraviolet-absorbing compound is derived from at a first reactant being a UV absorber comprising a carbon-nitrogen triple bond and a second reactant having amine functionality. By a second embodiment, the ultraviolet-absorbing compound is derived from a first reactant being a UV absorber comprising amine functionality and a second reactant comprising a carbon-nitrogen triple bond. In both embodiments of the invention, the second reactant may be a small molecule, a monomer, a macromolecule, a biomolecule, or a polymer.The inventions ultraviolet-absorbing compounds are directed toward formulations and applications that serve to protect against UV radiation in any art. Exemplary uses of the ultraviolet-absorbing compounds are in adhesive, agriculture, cleaning/polishing, coating, containers, encapsulation, fragrances, imaging, hoses/tubing, household/industrial/institutional, medical, membrane, molded parts, oilfield, packaging, personal care, personal protective equipment, pharmaceutical, printing, veterinary, and wood-care applications. Highly preferred uses of the ultraviolet-absorbing compounds are in personal care and performance chemicals.wherein R═
