<p>The green reflection colour of back surface mirrors produced by deposition of a reflecting layer over two reflection enhancing layers on a glass substrate is controlled by selection of the layer materials and thicknesses to provide a reflection colour having an a* value greater than -6, with a light reflection of at least 65%, preferably at least 70%. The inner reflection enhancing layer and reflecting layer are preferably of silicon, with the inner reflection enhancing layer having an optical thickness less than 125 nm; the intermediate reflection enhancing layer, which may be of silicon oxide, preferably has an optical thickness greater than 125 nm. The mirror may be produced by depositing the successive layers on a hot ribbon of glass during the glass production process.</p> |
