Abstract: A method for producing a windshield includes providing a sodium-containing outer and inner panes having, respectively, a glass transition temperature of Tg1 and Tg2, applying a functional agent including alkali metal ions having a larger cation radius than that of sodium ions within at least one subregion of the outer pane or over the total area of the outer pane and within at least one subregion of the inner pane or over the total area of the inner pane at a plurality of points, forming defect areas at the points of the outer pane containing the functional agent at a temperature of at least Tg1 and at the points of the inner pane containing the functional agent at a temperature of at least Tg2, removing the remaining functional agent, forming a layer stack from the outer pane, a thermoplastic intermediate layer and the inner pane and laminating the layer stack.

Abstract: A method for producing a windshield, includes (a) providing an outer pane and an inner pane, (b) heating the outer pane and the inner pane to at least their softening temperature, (c) jointly bending the outer pane and the inner pane or individually bending the outer pane and the inner pane, (d) cooling the outer pane and the inner pane, and (d) laminating the outer pane and the inner pane with the interposition of a thermoplastic intermediate layer to form a composite pane, wherein in procedure d) the outer pane and/or the inner pane are/is cooled in the first surface region at a first cooling rate and the outer pane and/or the inner pane are/is cooled in the second surface region at a second cooling rate, and the absolute value of the first cooling rate is greater than the absolute value of the second cooling rate.

Abstract: A method for producing a vehicle composite pane with improved impact protection, wherein at least a) an outer pane and an inner pane are provided, b) in at least a first partial region defect areas are introduced into the outer pane and/or inner pane, c) the outer pane and the inner pane are bent congruently together, d) a thermoplastic intermediate layer is placed onto the outer pane or the inner pane, e) the layer stack is completed with the inner pane or outer pane, and f) the layer stack composed of at least the outer pane, thermoplastic intermediate layer and inner pane is laminated to form a windshield, wherein the defect areas are introduced into the outer pane and/or inner pane by means of indentation.

Abstract: A windshield having an engine edge, a roof edge, and two side edges running between them, includes an outer pane made of glass with an outer surface and an interior-side surface and an inner pane made of glass with an outer surface and an interior-side surface, wherein the interior-side surface of the outer pane and the outer surface of the inner pane are connected to one another via a thermoplastic intermediate layer, and the windshield includes a first partial region, in which a transparent cover print including enamel is applied to the outer pane and/or inner pane, the first partial region is arranged along the engine edge and extends from the engine edge in the direction of the roof edge of the windshield, and the windshield has a transmission of at least 70% in the visible range of the light spectrum in the first partial region, at least in portions.

Abstract: A windshield having a motor edge, a roof edge, and two side edges running therebetween, at least including a first pane having an outer surface and an interior-side surface and a second pane having an outer surface and an interior-side surface, wherein the interior-side surface of the first pane and the outer surface of the second pane are connected to one another via a thermoplastic intermediate layer, and wherein the first thermoplastic intermediate layer includes, at least in a first portion, a first polymer film with a first stiffness and in a second portion includes a second polymer film with a second stiffness, the second stiffness is greater than the first stiffness, the second portion is arranged along the motor edge and extends from the motor edge in the direction of the roof edge of the windshield.
