Abstract
The invention provides improved high contrast, photopolymerizable compositions suitable for producing high contrast waveguides. The high contrast, photopolymerizable compositions of this invention include a nitrone compound component. The photosensitive composition is an admixture of a free radical polymerizable acrylate or methacrylate component having at least two ethylenically unsaturated groups, a photoinitiator, and a nitrone compound.
