A laminated glazing comprising first and second sheets of glass joined together by an interlayer structure comprising at least a first layer of adhesive interlayer material is disclosed. The surface compressive stress in a central region of a first major surface of the first sheet of glass is dependent upon the thickness of the first sheet of glass. For a thickness t of the first sheet of glass between 1.4 mm and 2.6 mm the minimum surface compressive stress CS.sub.min (in MPa) in the central region of the first major surface of the first sheet of glass is given by CS.sub.min(MPa)=21.0×t.sup.3−118.6×t.sup.2+236.9×t−a.sub.1, wherein a.sub.1 is between 135 MPa and 140 MPa. The second sheet of glass may be a sheet of chemically strengthened glass having a thickness between 0.3 mm and 1.0 mm. The laminated glazing may be fixed or movable in an aperture in a vehicle.

A manufacturing method of laminated curved glass includes steps: (1) providing a flat first glass plate and a flat second glass plate with a thickness of 0.1 mm to 2.2 mm; (2) impose the first glass plate and the second glass plate with strengthening treatment, the processed first glass plate and the processed second glass plate are in the shape of a flat plate, and the surface stress of the first glass plate or the second glass plate is 10-1000 MPa; and (3) Low temperature molding process, providing an adhesive film, and laminating the first glass plate processed in step (2), the adhesive film, and the second glass plate processed in step (2) in sequence, and then performing the low temperature press molding process to obtain the laminated curved glass. The method of the present bents the glass without high temperature to soften the glass.

An antireflection optical body formed on an adherend includes an adhesive other than an epoxy adhesive applied on the adherend, and a fine structure body fixed to the adherend by the adhesive. A thickness of the adhesive and the fine structure body is 5.5 μm or more and 8.6 μm or less.

A laminated glazing comprising first and second sheets of glass joined together by an interlayer structure comprising at least first and second layers of adhesive interlayer material with a support sheet therebetween is disclosed. The laminated glazing is arranged such that the first layer of adhesive interlayer material is between the first sheet of glass and the support sheet, the second layer of adhesive interlayer material is between the second sheet of glass and the support sheet support material and at least a portion of the second major surface of the first sheet of glazing material faces the first major surface of the second sheet of glazing material. In the event of breakage of the first sheet of glass, the second layer of adhesive interlayer material remains attached to the support sheet thereby keeping the second glass sheet from becoming detached from the laminated glazing.

A method of forming an antireflection optical body includes: an application step of applying a photocurable resin onto one surface side of an adherend; a pressing step of pressing a substrate film having a fine structure body at one surface side against the photocurable resin from an opposite surface side by a light guide; a curing step of curing the photocurable resin by transmitting light through the light guide; and a peeling separation step of releasing the pressing of the substrate film and peeling fixed fine structure body that is fixed to the adherend through the cured photocurable resin substrate film while separating the fixed fine structure body from fine structure body on the substrate film other than at a location fixed through the photocurable resin such that the fixed fine structure body is formed on the adherend as an antireflection optical body.

A circuit-including film comprising: a resin film (1); and a conductive fine wire circuit (A) and a conductive circuit (B) independent of the conductive fine wire circuit (A), which are arranged on one surface of the resin film (1), wherein the resin film (1) contains at least one resin selected from the group consisting of a polyvinyl acetal resin, an ionomer resin and an ethylene-(vinyl acetate) copolymer resin.

A disclosed laminated automotive glazing for displaying an image comprises a first glass sheet; a first interlayer; a luminescent film having luminescent capabilities; a second interlayer; and a second glass sheet, wherein the luminescent film is reactive to an activating light wavelength, and wherein the second interlayer is transparent to the activating light wavelength and the first interlayer has a transparency at the activating light wavelength of equal to or less than 1.0%.

A vehicle window pane having a plate-like window pane body which has an outer side facing the surroundings of the vehicle and an inner side facing away from the outer side and on whose inner side a shading arrangement is disposed, the shading arrangement being formed by a liquid crystal arrangement which has a liquid crystal cell. The liquid crystal arrangement has two films between which the liquid crystal cell is disposed, and the liquid crystal arrangement is connected to the window pane body via at least one longitudinal-expansion compensation layer.

An interlayer film for laminated glass of the present invention comprises: a resin; a colorant; and a heat shielding material, wherein the interlayer film for laminated glass has a colored region in which a visible light transmittance of a laminated glass is 6% or more and 50% or less, provided that the laminated glass is produced using two clear glass plates having a visible light transmittance of 90.4% in conformity with JIS R 3202: 2011.

A privacy glazing structure may include an electrically controllable optically active material that provides controlled transition between a privacy or scattering state and a visible or transmittance state. To make electrical connections with electrode layers that control the optically active material, the privacy glazing structure may include an offset pane arrangement. The structure may include first and second panes that contain an optically active material. The two panes may be sandwiched by two laminated outer panes. In some examples, the first and second panes are recessed relative to the laminated outer panes along their side edges to define recesses in which electrical connection features are positioned. While the side edges may be recessed, the bottom edges of all the panes may be positioned flush with each other.
