<p>A UV absorbing polymeric composition has an E<sub>308</sub>/E<sub>524</sub> ratio of greater than 10, and contains an organic resin and titanium dioxide particles. The composition is particularly suitable for use in producing an end-use product, preferably in the form of a polymeric film, exhibiting UV absorbing properties and improved transparency. In one embodiment, the composition may be produced from a masterbatch composition containing an organic resin, an organic dispersing medium and titanium dioxide particles. The masterbatch is preferably prepared by mixing a pre-dispersion of the titanium dioxide particles in the organic dispersing medium, with the organic resin.</p> |
