A laminate comprising a base material film, a resin layer (1) having a detachable surface, and a heat-generating conductive layer in this order.

The present invention relates to a window pane and to a corresponding production method. The window pane (1) for a motor vehicle of the invention has a first pane and a second pane arranged parallel to the first pane, at least one intermediate adhesive layer (4) arranged between the first and second panes for forming a laminate therewith, wherein the intermediate adhesive layer (4) comprises at least one layer opening (7) or recess which is surrounded by an inside opening wall (4.1) of the intermediate adhesive layer (4), and a reinforcing adhesive material (8) provided in the layer opening (7) of the intermediate adhesive layer (4) which shows a higher strength or hardness than the intermediate adhesive layer wherein the reinforcing adhesive material is coplanar to the intermediate adhesive layer.

A method for producing laminated glass or a precursor thereof using a first glass pane with a thickness of at least 1.4 mm and a second glass pane with a thickness of not more than 1.0 mm, the first and second glass panes differing in curvature and/or locally in shape, includes aligning an arrangement including the first and second glass panes and a laminating film by positioning a side edge of the arrangement against a stop element; pre-fixing the aligned arrangement at at least two locations on the positioned side edge of the arrangement by one or more fixing elements and heating, after which the fixing element or elements are removed again; and forming a fixed arrangement by passing the pre-fixed arrangement through a roller arrangement with the pre-fixed side edge of the arrangement ahead. The arrangement is heated in sections during passage.

Compositions, laminates, films and/or composites made from thermoplastic polymers, such as thermoplastic polyurethane (TPU) are described. The films have one or more optical layers made from materials that allow the transmission of visible light and reflect or absorb UV light. An optical film is made from one or more TPU resins including a first UV absorber of the benzotriazole family or the triazin family, a light stabilizer, and a second UV absorber selected from a group consisting of benzotriazoles, benzophenones, triazin or benzylidene malonate. The second UV absorber may be present in a base resin combined with the TPU resin. The optical film is capable of blocking at least 99% of light having a wavelength

Laminated glass having two glass sheets are laminated by an adhesive interlayer film with specific inks having a pH≥7 applied to at least one side of the interlayer.

Provided is an interlayer film for laminated glass capable of enhancing the pour stability at the time of extrusion during production of the interlayer film for laminated glass, and having excellent shape stability. An interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass having a one-layer or two or more-layer structure, and includes a first layer containing a thermoplastic (meth)acrylic polymer and satisfies at least one of a first configuration that the thermoplastic (meth)acrylic polymer contained in the first layer is a thermoplastic (meth)acrylic polymer having a molecular weight distribution ratio of weight average molecular weight to number average molecular weight of 1 or more and 6 or less, and a second configuration that the thermoplastic (meth)acrylic polymer contained in the first layer is a thermoplastic (meth)acrylic polymer having a gel fraction of 5% by weight or less.

The present disclosure relates to an optical functional film for a head-up display, having two or more slow axis zones different in slow axis angles in the same plane, wherein a maximum difference between slow axis angles is more than 5° and less than 30°.

The present invention provides an automobile window glass on which a device that acquires electromagnetic waves is disposable. The automobile window glass includes an outer glass plate, an inner glass plate, an intermediate film disposed between the outer glass plate and the inner glass plate, and a blocking layer that is disposed on at least one of a surface on the vehicle interior side of the outer glass plate and a surface on the vehicle interior side of the inner glass plate. The intermediate film includes a functional layer having a transmission region that allows transmission so as not to affect reception of the electromagnetic waves, and an adhesion layer that is disposed on at least one surface of the functional layer and does not affect reception of the electromagnetic waves. The blocking layer has at least one opening at a position corresponding to the transmission region.

A laminated glass, a method for producing a laminated glass, and a reflective film that has end parts where the generation of wrinkles is prevented in a case where the laminated glass is produced by sandwiching the reflective film between two glass plates and that has a reflection wavelength range with a small variation are provided. The reflective film has wavelength-selective reflectivity. A thermal shrinkage rate in a case where the reflective film is held at 140° C. for 30 minutes is greater than 0.5% and smaller than 2.0%. The reflective film has at least one cutout portion on a side edge of the reflective film.

A process for manufacturing a colored laminated glazing including first and second glass sheets, the two sheets being connected together by a thermoplastic interlayer, includes depositing a stack of layers including functional layer on a face of the first and/or of the second glass sheet, liquid deposition, on a face of the first and/or of the second glass sheet, of a polymer layer including a coloring agent and polymer compounds, drying and optionally curing of the polymer layer, assembling the glass sheet, coated with the colored polymer layer, with a colorless transparent thermoplastic interlayer and with the second glass sheet, so that the colored polymer layer is in direct contact with the interlayer, degassing, and heat treatment under pressure and/or under vacuum of the laminated glass at a temperature of between 100° C. and 200° C.
