Novel ultraviolet absorbing compounds that are liquid in nature, are 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. This invention also concerns the end products, specific
broadly defined types of compounds providing such beneficial
characteristics, methods of making such low-color compounds, and methods
of producing such clear, UV protected end products.
