A UV absorbing polymeric composition has an E308/E524 and/or E36O/E524 ra tio of greater than 4, and contains an organic resin and zinc oxide particle s. 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 ma y be produced from a masterbatch composition containing an organic resin, an organic dispersing medium and zinc oxide particles. The masterbatch is pref erably prepared by mixing a pre- dispersion of the zinc oxide particles in t he organic dispersing medium, with the organic resin.
