At one or more points in at least a part of an area of the second area, a wedge angle δ.sub.g being a sum of respective wedge angles of the first and second glass sheets satisfies Formula (1): $\begin{array}{c}{\delta }_g=\frac{t}{R}\frac{\sin \mathrm{\phi cos\phi }}{n^2-{\sin }^2\phi }-\eta \frac{\cos \phi }{2\sqrt{n^2-{\sin }^2\phi }}-{\delta }_c\end{array}$

A composite pane having electrically controllable optical properties, includes an outer pane and an inner pane that are joined to one another via a thermoplastic intermediate layer, wherein a functional element having electrically controllable optical properties is embedded in the intermediate layer, the functional element including an active layer between a first carrier film and a second carrier film, wherein the intermediate layer contains a first thermoplastic material and the carrier films contain a second thermoplastic material, and wherein the first carrier film and the second carrier film are fused together along at least one region of the side edge of the functional element.

A laminated glass, includes an outer pane, an inner pane, at least two lamination layers arranged between the outer pane and the inner pane, and at least one design element, wherein the design element is formed on a partial region of a pane side of the outer pane or the inner pane from a pictorial black print having one or a plurality of unprinted regions, and an opaque, non-black underlay is arranged between the two lamination layers, which underlay is placed underneath the unprinted region(s) of the design element. The laminated glass has a design element with good contrast and good visibility and is suitable in particular as a vehicle window.

Provided is an interlayer film for laminated glass capable of enhancing the sound insulating property over a wide temperature range with width of at least 15 C. in a temperature region from 10 C. to 30 C. An interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass having a two or more-layer structure, the interlayer film includes a layer containing a cured product or a polyolefin resin, the cured product is a cured product of a photocurable compound or a moisture-curable compound, the layer containing a cured product or a polyolefin resin has a glass transition temperature of 10 C. or more and 0 C. or less, tan at the glass transition temperature of the resin layer of 2.5 or more, and a storage modulus G at 5 C. of the resin layer of 3.010.sup.4 Pa or more and 5.010.sup.6 Pa or less.

A vehicle glazing (10) wherein a light guide stack (22) is located between a portion of the inner transparency (26) and the outer transparency (28). The light guide stack includes a polycarbonate film (32) that is bonded to the transparencies by layers of PET (38, 40) that are secured to the polycarbonate film on one side by silicone (34, 36) and that are secured to the transparencies on the other side by PVB (42, 44). The terminal end of an extending tab of the polycarbonate film forms an edge that is connected to a light bar (14) that such visible light propagates through the light bar and into the polycarbonate film through the edge. Visible light propagates through etchings in the smooth surface of the polycarbonate film to form an image. An extension of one of the transparencies protects the polycarbonate tab and supports the light bar during installation of the glazing into the vehicle portal.

A film contains an electrically actuated liquid having variable optical opacity under the influence of an electric field. The film comprises first and second spaced apart substrates defining a first cavity therebetween in which some or all of the liquid is contained. The film also comprises a liquid trap in fluid communication with the first cavity via a first opening. The liquid trap contains liquid that may flow from the first cavity through the first opening due to the volume of first cavity decreasing. The film may be included in a laminated glazing. A method of preparing a cell for a liquid is also described, and such a cell may be part of a film having variable optical opacity.
