Patent ID: 8395059

Claim:
An electromagnetic wave shielding material comprising: a transparent substrate; a primer layer formed on the transparent substrate; and a convex pattern layer composed of a conductive composition formed in a prescribed pattern on the primer layer, wherein a thickness of a portion of the primer layer where the convex pattern layer is formed is thicker than a thickness of a portion thereof where the convex pattern layer is not formed; an interface between the primer layer and the convex pattern layer in the convex pattern layer-formed portion has any one or two or more sectional forms of (a) a sectional form where an interface between the primer layer and the convex pattern layer is complicated in a non-linear manner, (b) a sectional form having a layer where a component constituting the primer layer and a component constituting the convex pattern layer are mixed, and (c) a sectional form in which a component contained in the primer layer is present in the conductive composition constituting the convex pattern layer; the conductive composition contains conductive particles and a binder resin; and in observation by electron microscopic photography in a transverse cross section of the convex pattern layer, the conductive particles include those in which at least a part of the plural conductive particles has a fused continuation.
