Process for the production of panes pare - sun a neutral color in transmission, reflection color and pharmacological determined by reflection of heat, and the panes obtained by this

摘要

Process for manufacturing the glass panes having a coefficient of transmission of 5 to 40 in the region of the visible spectrum and the reflection properties of the heat by radiation respect which are transparent supports by the cathodic sputtering. / p & & p & is applied by the cathodic sputtering, a first layer of oxide 1 of the optical thickness 20 at 280 nm in the atmosphere containing oxygen and in the second layer, a layer of chromium nitride, 2 of the background [0001] 10 to 40 nm thickness in the atmosphere of rare gas and of nitrogen.
