<p>The purpose of the present invention is to provide novel primer compositions for use in bonding an electroconductive film, particularly an electroconductive metal oxide film, to the surface of a polymeric substrate. The novel primer compositions of the invention comprise copolymers of acrylic acid and substituted acrylate monomers such as methyl methacrylate. The construction of the article of the present invention preferably comprises a transparent polymeric substrate, such as acrylic or polycarbonate, on a surface thereof a primer composition of a copolymer of acrylic acid and a substituted acrylate monomer such as methylmethacrylate and deposited on the primer an electroconductive film, such as tin oxide. The effect of the primer composition of the present invention is to provide adequate adhesion of the electroconductive film to the polymeric substrate, as well as to prevent crazing and/or cracking of the electroconductive film or the polymeric substrate. The resulting article is particularly useful as a transparency in aircraft.</p> |
