A vacuum ring for deaerating a stack sequence includes a vacuum-stable flexible hose, which can be connected to a vacuum pump, has the shape of a closed ring, and has an opening to the interior such that the ring can hold an outer side edge of a stack sequence in order to form a deaeration channel along the side edge, wherein the vacuum ring has at least one electric heating element.

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.

The disclosure provides a method for manufacturing a heat insulated PVB film, in which insulated nanoparticles with a particle diameter of 1-800 nm are added in the manufacturing process of PVB film to allow production of a PVB film with high insulation and transmittance. The disclosure also provides a method for manufacturing heat insulated blast-resistant glass, in which two panes of glass are laminated and bound by the PVB film to obtain blast-resistant glass with high insulation and high transmittance. The method for manufacturing heat insulated blast-resistant glass needs not applying an additional insulation coating or insulation film on conventional glass products and therefore allows manufacturing process to be simplified and manufacturing costs to be reduced.

A process for the manufacture of a colored laminated glazing including at least two glass sheets connected together by a thermoplastic interlayer, includes deposition, by the liquid route, on a first glass sheet, of a polymeric layer including a coloring agent and polymeric compounds, drying and optionally curing of the polymeric layer, assembling of the glass sheet, coated with the colored polymeric layer, with a colorless transparent thermoplastic interlayer and with the second glass sheet, so that the colored polymeric layer is in direct contact with the interlayer, degassing, during which the air trapped between the glass sheets and the thermoplastic interlayer is removed, and heat treatment under pressure and/or under vacuum of the laminated glass at a temperature of between 60 and 200 C., during which the coloring agent present in the polymeric layer migrates toward the thermoplastic interlayer and during which the laminated glazing is assembled.

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.

Described herein is a transparent or translucent substrate at least partially coated with a quantum dot coating such that the coating is invisible in a first non-excited state of the coating and the coating is visible in a second excited state of the coating. Also described herein is a laminate, a glazing unit and a sunroof comprising the described coated substrate. A method of preparing the coated substrate is also described.

The present invention aims to provide an interlayer film for a laminated glass which is easily peelable without autohesion even after storage in a stacked state, and a laminated glass prepared using the interlayer film for a laminated glass. The present invention relates to an interlayer film for a laminated glass, having a large number of protrusions on at least one surface, the surface having an arrangement density of the protrusions of 3 protrusions/mm.sup.2 or more, and the protrusions having an area ratio of 15 to 75% to the surface.

Methods for preparing multi-layer optical laminates include placing an optical film that is free form an adhesive layer between first and second glass substrates that are free of an adhesive layer, placing this laminate under vacuum, and then heating the laminate under pressure to a temperature above the softening temperature of the optical film. The glass substrates are free of an adhesive layer but may include a silane surface treatment. The resulting multi-layer laminate is optically clear and does not show scattering of reflected light by the optical film.
