(Formula 1): Vx1={(VA1VB1)/VA1}100 (Formula 2): Vx2={(VA2VB2)/VA2}100

A method for obtaining a laminated curved glazing unit in which (a) a first glass sheet is provided, coated on at least part of one of its faces with a stack of thin layers, then (b), on part of the surface of the stack of thin layers, an enamel layer is deposited by screen-printing an enamel composition comprising 1 to 15% by weight of zinc oxide particles having a particle size distribution by volume such that the d90 is at most 5 m. After lamination (d) with an additional glass sheet, the enamel layer is turned towards a lamination interlayer.

Provided is a laminate and a hot melt-type adhesive label that suppress curling due to swelling while having a pulp-paper feel. The laminate includes a porous substrate layer and an adhesive resin receiving layer on one side of the porous substrate layer, and the adhesive resin receiving layer contains an amorphous resin.

Implementations for composite display cover are described and provide improved protection and durability to device displays as compared with conventional display protection technologies. The described composite display cover, for instance, utilizes an ultra-thin glass layer with a polymer film applied directly to the glass layer and a hard coat applied to the polymer film. The polymer film, for instance, is applied to the glass layer without an adhesive. Further, the composite display cover can be attached to a display, such as via an adhesive layer that adheres the glass layer to a surface of the display.

Disclosed is a method for preparing an eye-protecting screen protector, which aims to address the issues of reduced luminous efficiency, color fading and shortened life of nano-luminous materials in existing products due to moisture and oxygen penetration. This method involves binding inorganic nanoparticles with surface hydroxyl groups with nano-luminescent materials through cross-linking materials. After raw material preparation, adhesive mixing, coating and curing, and glass lamination, a dense microscopic barrier structure is formed after UV curing, effectively blocking moisture and oxygen. Nano-luminescent materials can absorb 400 nm-480 nm harmful blue light and convert it into 500 nm-750 nm beneficial spectra to achieve eye protection. The product structure from outside to inside consists of tempered glass, a light conversion layer, a PET transparent film, a silicone layer and a release film, and is suitable for electronic devices including mobile phones and tablets, combining long-term stability with efficient eye-protecting performance.
