A glass laminate, in which an inorganic laminated film having a total thickness of 90 to 500 nm is laminated on a surface of a glass plate with an adhesive film including a resin film interposed therebetween, a carbon-containing film thinner than the inorganic laminated film is attached to a surface of the inorganic laminated film, a storage elastic modulus of an outermost surface on the inorganic laminated film side that is measured by a nanoindentation method using a flat punch indenter under conditions of 1 Hz and 28° C. is 50 MPa to 30 GPa, and a loss coefficient of the outermost surface on the inorganic laminated film side that is measured by the nanoindentation method using the flat punch indenter under conditions of 1 Hz and 28° C. is 0.005 to 0.14.

An electronic device may include electrical components and other components mounted within a housing. The device may have a display on a front face of the device and may have a glass layer that forms part of the housing on a rear face of the device. The glass layer and other glass structures in the electronic device may be provided with coatings. An interior coating on a glass layer may include multiple layers of material such as an adhesion promotion layer, thin-film layers of materials such as silicon, niobium oxide and other metal oxides, and metals to help adjust the appearance of the coating. A metal layer may be formed on top of the coating to serve as an environmental protection layer and opacity enhancement layer. In some configurations, the coating may include four layers.

A polyimide (PI) substrate, including a glass substrate is provided, wherein a first PI layer is disposed over the glass substrate, and a second PI layer is disposed over the first PI layer. The first PI layer is formed with a first PI material, and the second PI layer is formed with a second PI material. Disposal of the second PI layer over the first PI layer allows for manual and complete peeling of the second PI layer from the first PI layer.

A coating composition includes phosphorus pentoxide (P2O5), aluminum oxide (Al2O3), boron trioxide (B2O3), zinc oxide (ZnO), I group-based metal oxide, and II group-based metal oxide. The coating composition includes by weight based on a total weight of the coating composition 35 to 55% P.sub.2O.sub.5, 5 to 35% Al.sub.2O.sub.3, 5 to 40% I group-based metal oxide, 5 to 10% B.sub.2O.sub.3, 1 to 5% ZnO, and 1 to 10% II group-based metal oxide.

Deadfront articles that include a tactile element formed on a first surface of a substrate and a visual element disposed on a second surface of the substrate opposite the first surface. The tactile element is positioned on the first surface of the substrate in a complimentary fashion to the visual element disposed on the second surface of the substrate. The tactile element may include a surface roughness portion having a surface roughness different than the surface roughness of an area bordering the surface roughness portion. The deadfront articles may be incorporated into an automobile interior to provide a visual and haptic display interface for a user.

Provided is a substrate for transferring microstructures such as a micro LED including an engraved mark. The substrate for transferring microstructures is less likely to cause a recognizing error of the engraved mark to occur in a reading device, and makes it possible to stably and continuously read the engraved mark.

A substrate for transferring microstructures includes a synthetic quartz glass substrate and a silicone pressure-sensitive adhesive agent layer provided on a front surface of the synthetic quartz glass substrate. The substrate includes an engraved mark provided in the from surface.

A method for applying a coating to a surface includes the step of providing a reaction mixture comprising a silicon alkoxide and an alcohol. A reaction limiting amount of water is added. The silicon alkoxides and water are allowed to react to form silica precursor particles during an initial reaction period. A coating precursor composition is prepared by adding an acid soluble in the alcohol to the reaction mixture during a second reaction period after the initial reaction period. The precursor silica particles grow to form silica nanofeatures having a major dimension that is larger than a major dimension of the silica precursor particles. The coating precursor composition is applied to a surface, and the alcohol and water are allowed to evaporate and the silica nanofeatures to adhere to the surface and form a nanostructured layer on the surface. A coating precursor composition and a coated article are also disclosed.
