[Prior Art]
[0002] 為了使電子裝置的外殼具有豐富色彩，傳統上可利用彩 色塑膠形成彩色塑膠外殼’或藉由喷漆方式在電子裝置 的外殼表面形成顏色層°然而’塑膠外殼與噴漆外殼不 能呈現良好的金屬質感。採用PVD轉膜技術可在外殼表面 形成具有金屬質感的顏色層。 [0003] 然習知技術中，利用PVD鑛膜技術於殼體表面形成的膜層 的色彩非常有限’目前能夠廣泛製備和使用'的PVD膜層主 要為金黃色、黑色等色系。與烤漆、陽極處理等工藝相 比，真空鍍膜層的顏色不夠豐富，嚴重限制了其在裝倚 鍍膜領域的競爭力。[0002] In order to make the outer casing of the electronic device rich in color, it is conventionally possible to form a colored plastic outer casing by using colored plastics or to form a color layer on the outer surface of the electronic device by painting. However, the plastic outer casing and the painted outer casing cannot exhibit good performance. metallic feel. A PVD transfer film technology is used to form a metallic layer of color on the surface of the outer casing. [0003] However, in the prior art, the color of the film layer formed on the surface of the casing by the PVD mineral film technology is very limited. The PVD film layer which can be widely prepared and used at present is mainly a color system such as gold yellow or black. Compared with the processes of baking varnish and anodizing, the color of the vacuum coating layer is not rich enough, which seriously limits its competitiveness in the field of coating.
