METHOD FOR FORMING IMAGE, METHOD FOR MANUFACTURING LIGHT-TRANSMISSIVE ELECTROMAGNETIC SHIELDING MATERIAL, AND LIGHT-TRANSMISSIVE ELECTROMAGNETIC SHIELDING MATERIAL

摘要

A method for easily forming a mesh-like image free of disconnection and a method for easily manufacturing a light-transmissive electromagnetic shielding material having a mesh-like conductive layer free of disconnection and an excellent electromagnetic shielding ability are provided. The image forming method comprises a step of forming a mesh-like image by forming a pattern on a base with an image-forming ink by intaglio printing using a cylinder having a mesh-like pattern of the recesses in the surface of the cylinder. The image forming method is characterized in that the areas of the bottoms of the recesses at the intersections of the mesh of the mesh-like pattern are reduced. The light-transmissive electromagnetic shielding material manufacturing method comprises a step of forming a mesh-like pretreating layer by forming a pattern on a transparent base with an electroless plating pretreating agent by intaglio printing using a cylinder having a mesh-like pattern of the recesses in the surface of the cylinder and a step of forming a mesh-like metal conductive layer on the pretreating layer by electroless plating. The manufacturing method is characterized in that the areas of the bottoms of the recesses at the intersections of the mesh of the mesh-like pattern on the cylinder are reduced.
