ABSTRACT:
The present invention relates to optical elements, such as ophthalmic elements, including a substrate, a compatiblizing coating that optionally includes a dendritic polymer on at least a portion of the surface of the substrate and a functional organic coating, such as, but not limited to, an alignment coating, a photochromic coating, or an aligned liquid crystal coating, in contact with at least a portion of the compatiblizing coating opposite the substrate. The present invention also relates to compatiblizing coating compositions of dendritic polymers that may be used to form compatiblizing coatings on the surface of an optical element, and methods of making optical elements using the compatiblizing coatings.
