Abstract
This invention relates to novel ultraviolet absorbing methine-based compounds comprising polyoxyalkylene moieties. Such compounds provide excellent, inexpensive, protection from ultraviolet exposure within various media, including, but not limited to, thermoplastics. The presence of polyoxyalkylene chains on the methine backbone permits such an introduction within thermoplastics while simultaneously providing very low degrees of migration from the target substrate. This invention also concerns methods of making the aforementioned ultraviolet absorbing thermoplastic compositions.
