Patent ID: 7745045

Claim:
A layered product comprising: at least a substrate layer, an aluminum foil, a chemical conversion layer, an olefinic resin layer having an adhesive property to metal, and a thermal bonding resin layer that are successively laminated, wherein a fluororesin layer, formed by a fluorine-containing copolymer having a crosslinking group and a curing agent that reacts with the crosslinking group, is interposed between the olefinic resin layer and the thermal bonding resin layer wherein the fluorine-containing copolymer contains as a monomer component, a fluoro-olefin monomer (1) represented by the formula; CF 2 ═CFX in which X indicates a fluorine atom, a chlorine atom, a hydrogen atom or a trifluoromethyl group, a hydroxyl-group-containing monomer (2) represented by the formula: CH 2 ═CHR 1 in which R 1 indicates —OR 2 or —CH 2 OR 2 (R 2 is an alkyl group having a hydroxyl-group) serving as a crosslinking group-containing monomer, a β-methyl-substituted α-olefin monomer (3) represented by the formula: CH 2 ═CR(CH 3 ) in which R indicates an alkyl group having 1 to 8 carbon atoms, a vinyl ether monomer (4) represented by the formula: CHR 3 ═CHOR 3 (CH 3 ) in which R 3 indicates an alkyl group having 1 to 8 carbon atoms, a monomer (5) represented by the formula: CH 2 ═CHR 3 in which R 3 is —OR 4 or —CH 2 0R 4 (R 4 indicates an alkyl group having a carboxyl group), and a monomer (6) which has no crosslinking functional group and is copolymerizable with any of the monomers 1), 2), 3), 4) and 5).
