Official abstract text for this publication.
Provided is a roughened plated sheet comprising a roughened plated layer having a roughened nickel plated layer and a zinc plated layer formed on at least one surface of a metal substrate in this order from the metal substrate side, wherein a ten-point average roughness Rzjis of a surface of the roughened plated layer, according to laser microscope measurement, is 3 μm or more.
Opening claim text (preview).
The invention claimed is: 1. A roughened plated sheet comprising a roughened plated layer having a roughened nickel plated layer and a zinc plated layer formed on at least one surface of a metal substrate in this order from the metal substrate side, wherein a ten-point average roughness Rz jis of a surface of the roughened plated layer, according to laser microscope measurement, is 3 μm or more; and a lightness L* of a surface of a roughened plated layer is 45 to 83. 2. The roughened plated sheet according to claim 1 , wherein a ten-point average roughness Rz jis of a surface of the roughened plated layer is 3 to 30 μm. 3. The roughened plated sheet according to claim 1 , further comprising another plated layer between the metal substrate and the roughened nickel plated layer. 4. The roughened plated sheet according to claim 3 , wherein the another plated layer is a nickel plated layer or a zinc plated layer. 5. The roughened plated sheet according to claim 1 , wherein an adhesion amount of the zinc plated layer forming the roughened plated layer is 3 g/m 2 or more. 6. The roughened plated sheet according to claim 1 , wherein the metal substrate is a metal sheet or metal foil comprising one pure metal selected from Fe, Cu, Al and Ni, or a metal sheet or metal foil comprising an alloy comprising one selected from Fe, Cu, Al and Ni.
