Abstract
This invention relates to a pane comprising a glass substrate (1) coated with at least one transparent, thin, low-emissivity and/or conducting 'functional' film (3), and with an 'intermediate' film (2) disposed between substrate (1) and functional film (3). The intermediate film (2) has an optical thickness between 150 and 195 nm, preferably at approximately 168 or 185 nm, so that the residual color of the reflected appearance of the substrate from the 'film side' of the pane is in the range of the blues.
