Description
本發明關於塗料領域，具體關於應用於玻璃基材的抗指紋塗料。The present invention relates to the field of coatings, and specifically to anti-fingerprint coatings applied to glass substrates.
電子產品，諸如手機、電腦、電視機等，在日常的工作和生活中變得越來越不可缺少。這些電子產品包括觸控螢幕和顯示面板等玻璃表面，由於頻繁的觸碰容易被指紋弄髒，影響產品的外觀。並且，對於某些消費者來說，具有消光(matt)效果的電子產品表面更具有吸引力。Electronic products, such as mobile phones, computers, televisions, etc., have become more and more indispensable in daily work and life. These electronic products include glass surfaces such as touch screens and display panels, which are easily stained by fingerprints due to frequent touches, affecting the appearance of the products. Moreover, for some consumers, the surface of electronic products with matt effect is more attractive.
目前，市場上廣泛採用雙層的塗料系統來塗覆電子產品的玻璃表面，即，產生消光效果的第一層和塗覆於第一層之上的提供抗指紋性能的第二層。雖然，雙層的塗料系統滿足了性能和外觀需求，但是在施用時操作複雜，耗時且耗力，從而增加了施用的成本。然而，雙層的塗料系統中抗指紋性能基本來自於含氟成分，其難以相容於常規溶劑，從而無法在單層塗料系統中同時實現消光和抗指紋的效果。Currently, a two-layer coating system is widely used on the market to coat the glass surface of electronic products, that is, a first layer that produces a matte effect and a second layer that is coated on top of the first layer to provide anti-fingerprint properties. Although the two-layer coating system meets the performance and appearance requirements, it is complex, time-consuming and labor-intensive during application, thereby increasing the cost of application. However, the anti-fingerprint performance in a two-layer coating system basically comes from fluorine-containing components, which are difficult to be compatible with conventional solvents, making it impossible to achieve both matting and anti-fingerprint effects in a single-layer coating system.
因此，期望開發一種單層的塗料組合物，使其同時滿足電子產品玻璃基材應用的各項性能和外觀需求。Therefore, it is expected to develop a single-layer coating composition that can simultaneously meet various performance and appearance requirements for glass substrate applications in electronic products.
本發明人進行了大量研究並開發出一種的塗料組合物，其可應用於玻璃基材作為單一層，具有優異的性能和外觀，包括抗指紋性、高附著力以及優異的消光效果等。The inventors have conducted extensive research and developed a coating composition that can be applied to glass substrates as a single layer and has excellent performance and appearance, including fingerprint resistance, high adhesion, and excellent matting effect.

本發明提供了一種經塗覆的基材，包括基材和塗覆於至少一部分基材上的所述塗料組合物。The present invention provides a coated substrate, including the substrate and the coating composition coated on at least a portion of the substrate.
本發明還提供了一種塗料組合物在形成單塗層用於為玻璃基材提供抗指紋性能、高結合力及/或優異的消光效果中的用途。The present invention also provides the use of a coating composition in forming a single coating for providing anti-fingerprint properties, high adhesion and/or excellent matting effect to a glass substrate.
