Process for preparing light transmissive electromagnetic wave shielding material, light transmissive electromagnetic wave shielding material and display filter

Abstract

The present invention provides a process for preparing a light transmissive electromagnetic wave shielding material having an excellent light transmissive property, an excellent electromagnetic wave shielding property, an excellent appearance property and an excellent legibility by a simple method. A process for the preparation of a light transmissive electromagnetic wave shielding material comprising; (A1) printing a pretreatment agent for electroless plating comprising a composite metal oxide and/or a composite metal oxide hydrate and a synthetic resin in a mesh pattern on a transparent substrate 11 to form a mesh-patterned pretreatment layer 12, and (A3) subjecting the pretreatment layer 12 to electroless plating to form a mesh-patterned metal conductive layer on the pretreatment layer 13.
