진공증착을하여반사율이높은반사막을형성하는것이공지되어있다.  It is known to form a highly reflective film by vacuum deposition.
페트 (PET)와같은플렉시블기재표면에반사율이높은은 (Ag),알루미늄 (A1), 니켈 (Ni),로듐 (Rh)등의금속을이용한진공증착을한후지지체에라미네이팅을 통한반사막의제조를할수있으나진공증착의경우고진공의챔버 (chamber)가 요구되며기재의형태및크기에제약을주고코팅두께가불균일하며많은 설비비로인한문제점이있다.  Manufacture of reflective film through lamination on support body after vacuum deposition using metal with high reflectivity (Ag), aluminum (A1), nickel (Ni), rhodium (Rh) on the surface of flexible substrate such as PET However, vacuum deposition requires a high vacuum chamber, constrains the shape and size of the substrate, the coating thickness is uneven, and there are problems due to the large equipment cost.
[6] 더불어,증착공정에서오는낮은수율과느린속도높은설비비용으로판단할 때높은가격으로산정되는한계를갖고있다. [6] In addition, there is a high price limit when judging from the low yields and slow speeds of the deposition process and high equipment costs.
[7] 따라서본발명자들은이러한문제점을해결하기위하여부단히노력한결과 성공적으로본발명에도달하게되었다.즉，본발명은코팅방법으로제조된 금속박막을형성하고표면처리를통하여내후성을확보하였으며，패턴형식의 점착제프린팅으로라미네이팅공정을가져가높은반사율과휘도를유지할수 있는내후성강한반사필름을개발하게되었다. [7] Therefore, the present inventors have made great efforts to solve these problems, and have successfully reached the present invention. The present invention has formed a metal thin film manufactured by a coating method and secured weather resistance through surface treatment. The adhesive printing resulted in a laminating process that developed a weather-resistant reflective film that can maintain high reflectivity and brightness.

[129] 이와같이,표면처리를하는경우금속층에대한우수한내후성을제공할수 있게되어물리적화학적내후성을동시에확보할수있게된다.여기에 접착제층을패턴인쇄하여접착제패턴층으로형성하는경우 air gap을유지하여 높은반사율과휘도를유지하는둥의우수한광특성을제공할수있다.  [129] In this way, the surface treatment can provide excellent weather resistance to the metal layer, thereby attaining physical and chemical weather resistance at the same time. When the adhesive layer is pattern-printed to form the adhesive pattern layer, the air gap is maintained. It can provide excellent light characteristics of the barrel, which maintains high reflectance and brightness.
