SCREEN FOR SILK-SCREEN PRINTING AND METHOD FOR OBTAINING GLAZING UNITS PROVIDED WITH ELECTRICALLY CONDUCTIVE PATTERNS

摘要

The invention concerns a screen (1) for silk-screen printing, intended for printing electrically conductive patterns (5, 6, 7, 8) on glass sheets and comprising a main mesh (2), the aperture size of the main mesh (2) being larger in a side portion (C) than in the central portion (A), said screen (1) further comprising, on at least a double mesh area located in said central portion, at least one secondary mesh (3) attached to one face of the main mesh (2), the aperture size of the secondary mesh (3), or of each of the secondary meshes, being larger than that of the main mesh (2) in the central portion, and the aperture of the secondary mesh (3), or of each of the secondary meshes, forming, with that of the main mesh (2), an angle α of 1 to 89°. The invention also relates to a method for obtaining this screen, a method for producing glazing units and a glazing unit (4) coated on one face thereof with electrically conductive patterns (5, 6, 7, 8).
