PROBLEM TO BE SOLVED: To provide a laminate in which anode oxidation is combined with electrodeposition coating and which can have both of versatility being applicability to general composite coating films and multi-coloring properties being colorability in various colors and is used in aluminum building materials obtained by using aluminum or an aluminum alloy as a base material.SOLUTION: The laminate 10 is obtained by laminating an anodic oxide film 12, an electrodeposition coating film 13, a primer layer 14 comprising a polyolefin-based primer modified with a polar group, and a powder coating film 15 in this order on the surface of the base material 11 made of aluminum or the aluminum alloy. The polyolefin-based primer modified with the polar group is obtained by applying one or more modifications selected from the group consisting of acid modification, acrylic modification and polyester modification to an original polyolefin-based primer. The polyolefin-based primer is modified with maleic acid or/and chlorinated. |
