Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a resin-coated aluminum plate which has not such a problem that the appearance quality thereof is deteriorated due to crystallization of a coating resin during storage, the resin-coated aluminum plate having high adhesive strength between an aluminum plate and a resin layer, and the resin layer that has excellent alcohol resistance.SOLUTION: The resin-coated aluminum plate is obtained by coating the anodized surface of the aluminum plate, that is subjected to non-porous anodic oxidation treatment, with a polyamide resin layer which contains: a resin component comprising a mixed resin of 50-80 parts mass of aromatic polyamide (A), that contains 90 mol% or more of a structural unit produced by a polycondensation reaction of meta-xylylene diamine with adipic acid, with 50-20 parts mass of nylon 6 (B) (on condition that the total of (A) and (B) is 100 parts mass); and a crystallization accelerator of 0.01-1.0 part mass based on 100 parts mass of the resin component and which has 177-200°C crystallization start temperature, when heated, melted and cooled at 10°C/min for DSC measurement, and 2 minutes or shorter semi-crystallization time at a 120°C isothermal crystallization test. |
