Problems solved by technology

However, in this technology, there is a problem that large-scale processing such as plasma treatment must be performed
[0007] When the graft polymer is bonded to the surface of the substrate, sufficient adhesion between the substrate and the metal is obtained, but under conditions such as high humidity, the problem of peeling of the graft polymer from the metal occurs.

Further, 44.2 g (0.18 mol) of 11-bromo-1-undecene (95%) was added dropwise thereto, and the reaction was carried out at room temperature. The reaction was terminated after 1 h. The reaction solution was poured into ice water and extracted with ethyl acetate to obtain a mixture containing Compound a as a yellow solution. 37 g of this mixture were dissolved in 370 mL of acetonitrile, and 7.4 g of water were added. Add 1.85g p-toluenesulfonic acid monohydrate and stir at room temperature for 20min. The organic phase was extracted with ethyl ...

Abstract

A method for manufacturing a conductive pattern material is provided with a process of directly bonding a graft polymer, which has a functional group and a crosslinkable functional group that can mutually interact with conductive particles, on a substrate in a pattern; a process of forming a conductive particle adsorbing layer by permitting the functional group which can mutually interact with conductive particles in the graft polymer to adsorb conductive particles; and a process of forming a crosslinking structure in the conductive particle adsorbing layer by applying energy to the conductive particle adsorbing layer. In this method, a conductive pattern material provided with a conductive pattern which has a high resolution without interruption and has excellent durability can be manufactured. The conductive pattern material can be also obtained by introducing a functional group which can mutually interact with an electroless plating catalyst, instead of the functional group which can mutually interact with conductive particles, and by adsorbing the electroless plating catalyst and the like and performing electroless plating process.

Description

technical field [0001] The present invention relates to a method for producing a conductive pattern material, and more specifically, to a method for producing a conductive pattern material used as a printed wiring board. Background technique [0002] Conventionally, various conductive pattern materials have been used in the manufacture of wiring boards. As a representative of such materials, the general method is to place a conductive material formed by a known method such as vacuum evaporation deposition on an insulator, perform protection treatment on it, remove a part of the protection film previously formed by pattern exposure, and then perform etching treatment. Form the desired pattern. Such a method has at least four complicated steps as necessary steps. In particular, in this method, when wet etching is performed during the etching process, a step of treating the waste liquid is necessary, which is necessary but more complicated. [0003] As another method of form...
