Document Type and Number:
Japanese Patent JP6983969
Kind Code:
B2
Abstract:
To provide a resin-coated metal laminate that has high designability, and can be formed in a thin film.SOLUTION: A resin-coated metal laminate 10 comprises at least a resin layer 11, a barrier layer 13 and a sealant layer 16 in this order. The resin layer 11 is made of polyimide resin containing colored pigment, and the resin layer 11 film thickness is 1 to 15 μm. Corrosion-preventing layers 12,14 are provided at least on a surface on the sealant layer 16 side of the barrier layer 13. An adhesive layer 15 is provided between the sealant layer 16 and the barrier layer 13 for which the corrosion-preventing layers 12,14 are provided. The corrosion-preventing layers 12,14 are layers made of corrosion-preventing treatment agent containing chromium fluoride, phosphoric acid and polyvinyl alcohol, and the adhesive layer 15 is a layer made of adhesive agent containing maleic anhydride modified polypropylene and epoxy resin.SELECTED DRAWING: Figure 1
