    Abstract: The present application relates to a method of preparing a metal pattern having a 3D structure, a metal pattern laminate, and use of the metal pattern laminate. According to the method of preparing a metal pattern, the metal pattern having a 3D structure can be effectively formed on a receptor. Especially, the metal pattern having a 3D structure can also be effectively and rapidly transferred to a surface of the receptor, such as, a flexible substrate, to which the metal pattern is not easily transferred. The metal pattern laminate prepared using the method can, for example, be usefully used for metal layers of flexible electronic devices or metal interconnection lines.

    Abstract translation: 本申请涉及一种制备具有3D结构，金属图案层压板和使用金属图案层压体的金属图案的方法。 根据制备金属图案的方法，可以在受体上有效地形成具有3D结构的金属图案。 特别地，具有3D结构的金属图案也能够被有效且快速地转移到金属图案不容易转印到的受体的表面，例如柔性基板。 使用该方法制备的金属图案层叠体可以例如用于柔性电子器件或金属互连线的金属层。
