<P>PROBLEM TO BE SOLVED: To provide copper foil for a plasma display electromagnetic wave shielding filter having the characteristics that the color of a laminate face therein is a black system; there is no falling of fine roughened particles or the like; the laminate face has low roughness, and the laminate face has high smoothness which are particularly strongly required in the copper foil for a plasma display electromagnetic wave shielding filter. <P>SOLUTION: A fine roughened particle treatment layer of copper is applied to at least one side of copper foil, and also, ten point average roughness Rz is controlled to ≤2.0 μm. Then, the copper foil for a plasma display electromagnetic wave shielding filter having the characteristics of black color, low roughness and high smoothness in which surface system XYZ(Yxy)Y described in JIS Z8701 is ≤8.0, and also, specular gloss measured at Gs(60°) according to JIS Z8741 is ≥40, can be obtained. <P>COPYRIGHT: (C)2008,JPO&INPIT |
