Description

Non-planar tempered glass with grain decoration

The present invention relates to a non-planar tempered glass with textured decoration, and more particularly to a non-planar tempered glass that does not require the use of a substrate to carry a grain pattern.

For the appearance of the article, a 3D tempered glass film protective film containing a textured film was gradually developed. Since such a tempered glass protective film has a textured film and a glass film, it can simultaneously enhance the aesthetic appearance of the article and the effect of easy cleaning.

The existing 3D tempered glass protective film containing the grain film usually has the structure of the grain film structure composed of ink (20 μm), NCVM, UV grain (30 μm), PET (50 μm), OCA (25 μm), and the whole process. The thickness is about 125 μm. Moreover, when it is to be bonded to the glass substrate in the future, it is necessary to cut the grain film to a thickness of 0.05 to 0.1 mm from the single side of the glass to be applied to the glass substrate.

Therefore, the conventional 3D tempered glass protective film containing the grain film is not only inefficiently bonded to the glass substrate because the overall thickness is too thick. At the same time, because it needs to be cut, it cannot be aligned with the edge of the glass (white edge is produced), which affects the aesthetic problem.

Therefore, how to overcome the above-mentioned shortcomings through the improvement of structural design has become one of the important topics to be solved by this undertaking.

The glass The glass substrate has an inner surface and an outer surface opposite the inner surface. The solid optical adhesive layer is disposed on the inner surface of the glass substrate. The solid optical decorative layer is disposed on the solid optical adhesive layer, wherein a surface of the solid optical decorative layer has a specific grain pattern. The coating layer is disposed on the solid optical decorative layer to directly cover the specific texture pattern. The light shielding layer is disposed on the plating layer. Wherein the solid optical adhesive layer, the solid optical decorative layer and the coating layer are covered by the light shielding layer.

In order to solve the above technical problems, another technical solution adopted by the present invention is to provide a non-planar tempered glass with a decorative texture, including a glass substrate, a solid optical adhesive layer, a solid optical decorative layer, and a light shielding layer. The glass substrate has an inner surface and an outer surface opposite the inner surface. The solid optical adhesive layer is disposed on the inner surface of the glass substrate. The solid optical decorative layer is disposed on the solid optical adhesive layer, wherein a surface of the solid optical decorative layer has a specific grain pattern. The light shielding layer is disposed on the solid optical decorative layer to directly cover the specific texture pattern. Wherein the solid optical adhesive layer and the solid optical decorative layer are covered by the light shielding layer.
