Abstract
An electromagnetic wave reflection-preventing material having a structure formed by successively laminating (A) an electromagnetic have reflecting metallic material layer, if needed, (B) a substrate layer, (C) a resin layer containing a powder of at least one selected from ferrite, carbon, metal powder and an electrically conductive metallic oxide, and, if needed, a good dielectric material, if needed, (D) a supporting film layer, and (E) a pattern coating layer prepared in the form of a geometrical pattern, containing a metal powder and having a volume resistivity of 10.sup.-3 to 10.sup.10 .OMEGA..multidot.cm, preferably further laminating (F) a clear or colored coating layer; and an electromagnetic wave reflection-preventing material which is obtained by substituting (G) a molded sheet layer formed by coating a coating composition prepared by dispersing the above powder into a binder onto a substrate having void, and molding under pressure for (C) a resin layer; and an electromagnetic wave reflection-preventing method which comprises applying the electromagnetic wave reflection-preventing material onto a structure, or which comprises applying a laminate obtained by removing the electromagnetic wave reflecting metallic material layer (A) from the electromagnetic wave reflection-preventing material onto an electromagnetic wave reflecting structure having a metallic surface.
