Abstract

The present invention provides an acid-resistant protective coating, preferably an acid- and abrasion-resistant protective coating, for thermoplastic transparencies, particularly aircraft transparencies. The coating is prepared from a silica-free protective coating precursor composition comprising a multifunctional ethylenically unsaturated ester of acrylic acid, a multifunctional ethylenically unsaturated ester of methacrylic acid, or a combination thereof; and an acrylamide.
