Abstract
Molded optical articles and methods of making them are disclosed herein. Optical articles comprise a photopolymerizable composition disposed on a major surface of a substrate. The photopolymerizable composition comprises: a silicon-containing resin comprising silicon-bonded hydrogen and aliphatic unsaturation, and a platinum catalyst providing from about 0.5 to about 30 parts per million of platinum. The major surface imparts a positive or negative lens to the photopolymerizable composition. Optical articles also include those that have been photopolymerized using actinic radiation having a wavelength of 700 nm or less.
