ELECTROMAGNETIC WAVE SHIELD MATERIAL, COMPLEX FILTER AND IMAGE DISPLAY DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an electromagnetic wave shield material which has a large conductivity in spite of having a conductive pattern layer formed from a conductive ink, and which is reduced in reflection of external light from the side of a transparent base, and has an untinted adhesive layer made of acrylic resin on the side of the conductive pattern layer.

SOLUTION: An electromagnetic wave shield material includes: a transparent base; a primer layer formed on the transparent base; a conductive pattern layer formed on the primer layer and having a given pattern; and an adhesive layer made of a carboxyl group-containing acrylic resin and stacked on the side where the conductive pattern layer is formed. The conductive pattern layer contains metal particles and a binder resin. The distribution of the metal particles in the conductive pattern layer is relatively rough near the primer layer and dense near the top of the conductive pattern layer. The adhesive layer made of carboxyl group-containing acrylic resin contains 1H-benzotriazol.
