Zusammenfassung:The coating compositions which are curable upon exposure to ultraviolet radiation under a non- inert atmosphere, such as air, com- prise (a) one or more UV light cross- linkable polyfunctional acrylate monomers of specified formula, (b) colloidal silica, (c) an acryloxy functional silane of specified formula and (d) a combination of ketone- type and hindered amine-type photoinitiators. The compositions are used to form abrasion resistant coatings on substrates such as plastics or metal articles, particularly transparent polycarbonate articles.
