<P>PROBLEM TO BE SOLVED: To provide a conductive precoated aluminum alloy sheet excellent in electrical conductivity, scratch resistance and fingerprinting resistance. <P>SOLUTION: The conductive precoated aluminum alloy sheet 1 includes a substrate 2 comprising an aluminum alloy sheet, a chemical conversion film 3 formed on one or both surfaces of the substrate, and the conductive layer 4 formed on the chemical conversion film 3. The conductive layer 4 comprises 10-99 pts.wt. of a synthetic resin in which an acrylic resin and a urethane resin are blended at a prescribed blending ratio, and 1-90 pts.wt. of colloidal silica dispersed in the synthetic resin. The thickness T of the conductive layer 4 is 0.05 to 1.0 μm, the surface roughness Ra of the substrate is 0.1 to 0.8 μm, and the ratio of the thickness T of the layer 4 to the surface roughness Ra of the substrate (T/Ra) is 0.07 to 4.0. <P>COPYRIGHT: (C)2011,JPO&INPIT |
