Protection coating for optical discs, aspherical lenses, and optical waveguides

Photopolymerizable acrylic coatings are widely used in present day optical devices. However they usually failed on the inadequate optical parameters and low water resistance. A novel class of the photopolymerizable coatings on the basis of multifunctional carbonate methacrylates with unique combination of properties is described. Their applications range from optical discs to different kinds of lenses and gradient elements for optical waveguides.
