BACKGROUND

[0002] It is known that inorganic glass-based coatings impart specific qualities to surfaces. The glass fraction of the coating, often referred to as glass frit or glass fluxing agent, imparts specific chemical and physical properties to the coating. These are, for example, chemical resistance, abrasion and scratch resistance, and thermal stability. Inorganic coatings are notable in comparison with coatings having an organic matrix in terms of higher gloss and greater resistance to UV radiation. By adding colour pigments, anti-reflection additives or matting additives, various possibilities are provided in terms of aesthetics and design for differentiating and structuring the coated panels and articles manufactured therefrom. The coating operation itself is often referred to as enamelling, glazing, decorating or printing. There are a variety of technically defined methods and apparatuses for coating. In addition to dry coating methods such as by electrostatic powder coating, there are many coating methods in which liquid or paste-like coating materials are applied. The paste can be applied to the surface of the panel by various methods, for example by silk screen printing, pad printing, transfer printing methods or by dipping and spraying methods. The paste is usually composed of ground glass powder, optionally added pigments and / or additives, and organic auxiliaries which are removed during the baking, flow and levelling of the coating. For the coating of glass, glass-ceramic or ceramic panels, there are a variety of known enamel compositions.

[0021] The glass panel further comprises a matte layer 100 formed on the front face 101 of the glass panel 10, a texture layer 11 formed on the matte layer 100 and a background layer 12 formed on the back face 102 of the glass substrate 10, wherein the texture layer 11 provides a metallic texture structure to the glass panel, which is generally applied at least partially, preferably entirely, in a regular or irregular pattern to the glass substrate 10. The background layer 12 provides a background color to the glass panel, which, in combination with the texture structure of the texture layer 11, enables the glass panel to exhibit a metallic effect in different colors. For example, if the background color is gray, the glass panel can exhibit a silver effect.

In this embodiment, the glass panel comprises a glass substrate 20 having a front face 201 facing the observer and a back face 202 opposite to the front face.

The background layer 22 provides a background color to the glass panel, which, in combination with the texture layer of the texture layer 21, enables the glass panel to exhibit an effect in different colors. For example, if the background color is gray, the glass panel can exhibit a silver effect.

In step S15 a heat treatment is performed to sinter the texture layer and the background layer.

[0025] More specifically, for the glass panel shown in Figure 1 In step Sll, a matte layer 100 is formed on the front side 101 of the glass substrate 10, which can be formed by acid etching, sandblasting, calendering, printing, etc. to form a matte structure, i.e. the matte layer 100, in the glass substrate 10.

[0026] In step S12, a background layer 12 is printed or sprayed on the back side 102 of the glass substrate 10, which is mainly formed by a high-temperature inorganic ink containing pigments to provide a background color for the glass panel. The obtained glass panel is subjected to a high-temperature heat treatment

[0027] Then in step S14, a texture printing is performed on the matte layer 100 using a high-temperature ink to form a texture layer 11. Finally, the obtained glass panel is subjected to a high-temperature heat treatment to enable the printed ink to penetrate into the glass substrate 10. The texture layer 11 and the background layer 12 in the glass panel thus obtained cannot be physically separated.

[0028] The matte layer can also be performed after the heat treatment of the background layer and the texture layer.

In step S21, a matte layer is formed on a glass substrate, in step S22 a texture layer printing is performed. In step S23 a background layer is applied, then a heat treatment is performed, in step S24 a heat treatment is performed to sinter the texture layer and the background layer.

In specific embodiments, the surface roughness Ra of the matte layer 100 is in the range of 0.1 µm to 5.0 µm, the glossiness is in the range of 0 to 100 GU, and the haze is in the range of 0 to 100 NTU.

[0031] In step S22, texture printing is performed on the back surface 202 of the glass plate using high-temperature ink to form a texture layer 21.

Finally, the obtained glass panel is subjected to high-temperature heat treatment to enable the printed ink to penetrate into the glass substrate 20. The texture layer 11 and the background layer 12 in the glass panel thus obtained cannot be physically separated.

[0032] The matte layer can also be formed after the heat treatment of the background layer and the texture layer.

[0033] In the present application, the high-temperature inorganic ink used for the texture layer comprises the following components, in wt%:

[0034] Component wt% F2O 0.5-2.5 Na2O 16-24 Al2O3 1-5 SiO2 35-45 K2O 0.5-2.5 TiO2 3-9 ZnO 11-19 Organic solvent 10~18
