Abstract: A laminate includes a layer containing a polyaniline-based polymer and a phenoxy-based resin, and a layer containing zinc and/or a zinc alloy, a laminate includes, in sequence, a layer containing a polyaniline-based polymer and a phenoxy-based resin, a layer containing zinc and/or a zinc alloy, and an aluminum or aluminum alloy layer. A rust prevention method includes forming a layer containing a polyaniline-based polymer and a phenoxy-based resin on a layer containing zinc and/or a zinc alloy or on a layer containing zinc and/or a zinc alloy disposed on an aluminum or aluminum alloy layer. The laminates and the rust prevention method are for reducing the formation of rust on the layer containing zinc and/or the zinc alloy or the aluminum or aluminum alloy layer for a long period of time.

Abstract: An anti-corrosive coating composition having anti-corrosion performance which enables the anti-corrosive coating composition to reduce the generation of rust by salt water spray testing. The anti-corrosive coating composition contains polyaniline component and coating film component. The coating film component is composed of phenoxy resin.
