The present invention is a windshield on which an information acquisition device that acquires information from outside of a vehicle by emitting and/or receiving light can be arranged, the windshield including: an outer glass plate; an inner glass plate; an interlayer film arranged between the outer glass plate and the inner glass plate; and a mask layer laminated on at least one of a surface on a vehicle interior side of the outer glass plate and a surface on a vehicle exterior side of the inner glass plate, in which the interlayer film includes a colored shade region, a transparent non-shade region, and a transparent sheet member that is fitted into at least one through hole formed over the shade region and the non-shade region.

A polymer film and laminated glass manufactured using the polymer film. The polymer film includes a first and second layer, and a third layer disposed between the first and second layers, and the two surfaces of the third layer are in contact with the first and second layers, respectively. The surface of the first layer that is not in contact with the third layer is a first surface, and the surface of the second layer not in contact with the third layer is a second surface, wherein the first surface has a void volume (Vv) value at a material ratio of 10% ranging from 3 μm.sup.3/μm.sup.2 to 30 μm.sup.3/μm.sup.2 and a dale void volume (Vvv) at a material ratio of 80% less than 2 μm.sup.3/μm.sup.2, and the ratio of the maximum pit height (Sv) of the first surface to the thickness of the first layer is 0.2 or less.

A method of preparing a glazing, comprising: stacking a first glass sheet, a first interlayer, a photopolymer film, a second interlayer, and a second glass sheet to provide a lamination stack; &airing the lamination stack; autoclaving the lamination stack to provide a laminated glazing; applying a reactive light to the photopolymer film in the laminated glazing, wherein reactive light is applied to the laminated glazing through a master holographic film; and bleaching the laminated glazing such that the photopolymer film is no longer reactive to light exposure.

A packaged film assembly includes a packaging material and a switchable film. The switchable film is packaged in and attached to at least a portion of the packaging material.

The present invention provides a windshield on which an information acquisition device that acquires information from outside of a vehicle by emitting and/or receiving light is disposable, the windshield including: a glass plate; and a heating wire that is provided on the glass plate and to which a current is applied. The glass plate includes at least one information acquisition region that faces the information acquisition device and through which the light passes, the heating wire includes a plurality of linear main body portions that pass through at least the information acquisition region and a linear linking portion for linking the plurality of main body portions, and at least one of the linking portions includes a heat generation suppressing means for suppressing heat generation when a current is applied.

A multi-layer laminate includes a glass panel unit, an intermediate film, and a transparent plate. The transparent plate is assembled to the glass panel unit via the intermediate film. The glass panel unit includes a first and second glass panel, and an evacuated space. The evacuated space is interposed between the first and second glass panel. A method for manufacturing the multi-layer laminate includes a step. The step includes exhausting a gas from a bag, loaded with the glass panel unit, the intermediate film, and the transparent plate, to cause the bag to shrink and thereby assembling, using the bag thus shrunk, the glass panel unit and the transparent plate via the intermediate film. The step includes raising a pressure inside the bag from a pressure at an initial stage of heating while increasing a temperature of the intermediate film to a predetermined temperature at which the intermediate film softens.

To improve the visibility of an image displayed on a display from the inside of a vehicle, in a vehicle window glass having the display.

The vehicle window glass has a glass member and a display mounted on said glass member, wherein the visible light transmittance T [%] of said vehicle window glass at the portion including said display and the luminance L [cd/m.sup.2] of the display satisfy T≤0.1×L.

Embodiments of a vehicle interior system are disclosed. In one or more embodiments, the system includes a base with a curved surface, and a display or touch panel disposed on the curved surface. The display includes a cold-bent glass substrate with a thickness of 1.5 mm or less and a first radius of curvature of 20 mm or greater, and a display module and/or touch panel attached to the glass substrate having a second radius of curvature that is within 10% of the first radius of curvature. Methods for forming such systems are also disclosed.

Provided is an interlayer film for laminated glass capable of effectively enhancing the sound insulating property at 6300 Hz while effectively preventing deterioration in sound insulating property at 3150 Hz in laminated glass. An interlayer film for laminated glass according to the present invention has a one-layer structure or a two or more-layer structure and includes a resin layer containing a resin and a plasticizer. The interlayer film has a resonance frequency X of 550 Hz or more and 740 Hz or less, a loss factor Y in a secondary mode of 0.35 or more, and satisfies a formula: Y>0.0008X−0.142 in a measurement of resonance frequency in a secondary mode in a damping test for laminated glass according to a central exciting method of laminated glass, when the laminated glass is obtained by arranging the interlayer film between two glass plates of 25 mm wide, 300 mm long and 2 mm thick.

Provided is a sodium-neutralized ethylene acid copolymer ionomer composition containing a specified silane additive in a specified amount and having enhanced adhesion properties to glass, a masterbatch composition suitable for producing such ionomer composition, an interlayer made from such ionomer composition, and a glass laminate comprising such interlayer.
