Abstract

A dispersion includes a zinc oxide component, and an aromatic polyol which is represented by Formula (I) and which has terminal hydroxyl groups that form chelating bonds with zinc atoms of the zinc oxide component, wherein p and q are independently integers ranging from 1 to 40. A method for preparing the dispersion includes heating a composition including the aromatic polyol and a zinc-containing salt, so that the zinc-containing salt undergoes nucleophilic reaction and condensation reaction to form the zinc oxide component. A composition for preparing the dispersion is also disclosed.
