ABSTRACT:
In a transparent glass article comprising an electrically conductive, transparent, metal-based coating on a glass substrate and polyvinyl butyral material (PVB) bonded thereto, adhesion between the coating and the PVB is improved by a thin chromium-based film on the metal-based coating interfacing with the PVB. Adhesion is particularly improved in its resistance to exposure to UV radiation. In an electrically heated windshield application, the adhesion is improved by chromium-based film (24) between the metal-based coating (22) on a first glass template (12) and a PVB interlayer (26) mediate the first glass template and a second glass template (28). The glass article is produced according to a method aspect of the invention.
