Abstract

A forming method of a conductive pattern including a base material and a pattern of a composition gradient layer in which the composition continuously changes from a metal to a resin in a thickness direction from the farthest side to the base material toward the nearest side to the base material, includes: ejecting at least two kinds of ink compositions of an ink composition containing a metal and an ink composition containing a compound capable of being cured with active energy ray, or a polymer or oligomer, onto the base material by an inkjet method to fabricate the composition gradient layer.

Description

technical field

[0001] The present invention relates to a method of forming a conductive pattern using inkjet system technology, the conductive pattern has excellent manufacturing adaptability and high adhesion and conductivity, and wherein the conductive pattern forming an image does not change until it is dried; A method of manufacturing a printed circuit board using the forming method; and a printed circuit board manufactured by the manufacturing method. Background technique

[0002] Metal materials such as gold, silver, copper, platinum, aluminum, palladium, and nickel have long been used as materials constituting electrical components. First, because copper or silver materials are inexpensive, highly versatile, and highly conductive materials, they are widely used even now as materials for ensuring electrical continuity, such as circuit-forming parts of printed circuit boards, various Electrical contact parts and external electrode parts (such as capacitors, etc.). ...
