ABSTRACT:
An optical body and a method of producing oxidic, antireflective coatings on transparent plastic substrates of polydiethyleneglycoldiallylcarbonate comprising depositing a first coating having a high refractive index by vaporizing an oxide mixture of essentially zirconium dioxide with a content of 4 to 15 weight percent of aluminum trioxide and depositing a second layer having a low refractive index by vaporizing in a vacuum a borosilicate glass containing less than 5 weight-percent of alkali metal oxides. The depositing of at least the first coating is performed in an oxidizing residual gas atmosphere.
