CONDUCTIVE ELECTRICAL ELEMENT AND ANTENNA WITH INK ADDITIVE TECHNOLOGY

摘要

PROBLEM TO BE SOLVED: To form an electrical element or antenna by applying a conductive ink onto a pattern-printed coating. SOLUTION: A printing method is provided for printing the conductive ink on a printed pattern formed by a coating having additives for lowering a surface tension, the printed electrical element and the antenna (including an RFID antenna) are formed by using this method. The coating having the additives for lowering the surface tension is printed on a substrate in a prescribed pattern. Next the conductive ink is applied on this coating. Since the surface tensions of the coating and the substrate are different, the conductive ink flows away from the coating. This conductive ink is dried between printed coating pattern and a conductive element is formed.
