  • Patent number: 5093153
    Abstract: A coated object comprising a glass substrate and an organomineral film, such as an organosilicon compound, deposited upon at least a portion of the glass substrate wherein the coating is of a sufficient thickness and has a sufficient refractive index so as not to absorb energy within the visible spectrum. The object may additionally comprise at least one coating layer interposed upon the substrate beneath the organomineral film to improve the optical properties of the coated object. A method for making the coated object of the invention is described wherein a plasma deposition process is utilized to deposit the organomineral film upon the surface of the glass or glass-based substrate.
