The present invention relates to a method of manufacturing electrically conducting tracks on a transparent substrate, by screen printing with an electrically conducting paste, and to the transparent substrate provided with said tracks. According to the invention, conducting tracks are formed with a width less than or equal to 0.3 mm by applying, by screen printing, a thixotropic electrically conducting paste having a ratio of the viscosity without shear stress to the viscosity under shear stress under screen-printing conditions of at least 50 and having a silver content greater than 35% and of which at least 98% of the particles which form it have a size less than 25 &#x3bc;m, by means of a screen having at least 90 threads per cm, the coating of said screen being provided with slots, the narrowest width of which is equal to 0.25 mm&#xb1;0.05 mm, and by subjecting said tracks to baking.

Transparent substrate provided with electroconductive strips

The invention relates to a motor-vehicle window (,) provided with a peripheral region which engages, at leas in places, with a sealing element (,). The motor-vehicle window (,) can be fitted both in a fixed manner and in a moveable or sliding manner. The surface of the motor-vehicle window (,) is provided, at least in the peripheral region of contact with the sealing element (,), with a structurization (,) which produces a large number of locally delimited areas of contact between the sealing element (,) and the motor-vehicle window (,). In this way, excessively high adhesion forces, with the occurrence of noise during a relative movement between the window (,) and the sealing element (,), are avoided.

Motor-vehicle window with a structured surface in the peripheral region

A roof window pane for automobiles possesses, on the face towards the passenger compartment, a grating-type pattern of a material which impedes the passage of radiation, especially a baking finish. The grating-type pattern consists of superimposed gratings and has a moire structure.

Glazing pane with reduced light transmittance and method of

In the application of a decorative coating onto a glass pane by the silk screen printing process, a printing screen (2) is used, the printing surface of which extends beyond the peripheral face (9) of the glass pane (1). The printing ink situated in the meshes of the printing screen outside the glass surface in the printing operation is blown away or is sucked away by a suction nozzle (23), which is guided over the printing screen (2) behind the scraper (21).

Screen printing a glass pane with a decorative coating including blowing

In a method of making a glazing pane (1), printed with a decorative frame (15), in which the decorative frame (15) extends right to the peripheral surface (6) of the glass pane (1) independently of edge tolerances of the glass panes and of positioning tolerances of the glass pane and of the printing tools during the printing operation, a profiled strand (13), which extends the surface of the glass pane (1) beyond its peripheral face (6) is integrally formed immediately adjoining the peripheral face (6). The decorative frame (15) is printed on beyond the peripheral edge of the glass pane (1) and onto the profiled strand (13). After the printing ink has dried, the profiled strand (13) is removed from the glass pane (1).

Method of printing a glass pane with a decorative coating reaching the

To print on a glass sheet (42) with an edge-flush peripheral decorative frame (43, 45) the printing of decorative frame (43, 45) takes place with a silk-screen printing process in two printing operations, in which two partial areas (43, 53) of decorative frame (45) complementary to each other are printed consecutively. In the first printing operation a first partial area (43) of decorative frame (45) is aligned along two adjacent edges flush with corresponding glass sheet edges (46, 47), and in the second printing operation a second partial area (53) of decorative frame (45) is aligned edge-flush with the two other glass sheet edges (48, 49). The two partial areas (43, 53) of the decorative frame complementary to each other mutually overlap by measurement (D), which corresponds to the area tolerances of the glass sheets.
