Abstract

A UV light-curable composition comprises: (a) a first component, said first component being UV light-polymerizable polymer having a first index of refraction; and (b) a second component, the second component being UV light-polymerizable monomer having a second index of refraction, the second index of refraction being higher than said first index of refraction; wherein the first component polymerizes slower upon exposure to UV radiation than the second component.
