Electromagnetic-wave shielding and light transmitting plate and manufacturing method thereof
First Claim
1. A method of manufacturing an electromagnetic-wave shielding and light transmitting plate comprising a transparent film and a conductive pattern made of a conductive material, wherein the conductive pattern is formed on a surface of the transparent film by plating, the method comprising:
- a step of forming a negative pattern to be an opposite pattern of said conductive pattern, wherein the negative pattern is formed on the surface of the transparent film having a relatively high affinity for the plated layer by using a transparent resin having a relatively low affinity for the plated layer, and a step of forming said conductive pattern by subjecting the transparent film to plating treatment with plating solution after the formation of the negative pattern so as to attach the conductive material only to the surface of the transparent film not covered by the negative pattern.

Abstract
To manufacture an electromagnetic-wave shielding and light transmitting plate having a conductive pattern of which line width is narrow and open area ratio is high, a negative pattern 2 composed of dots is printed on a transparent film 1 having a high affinity for a plated layer of a conductive material by using a transparent resin having a low affinity for the plated layer and a backside coating layer 3 is formed by printing a transparent resin on the entire back surface of the transparent film 1. Then, a conductive material layer is formed by electroless plating to cover the film exposed surface not covered by the negative pattern 2 of the film 1, thereby forming the conductive pattern 4. After that, the blackening treatment is conducted, thereby obtaining the electromagnetic-wave shielding and light transmitting plate.
