Document Type and Number:
Japanese Patent JP6964808
Kind Code:
B2
Abstract:
Provided are: a composite laminate that makes it possible to endow the surface of a metal substrate such as aluminum with excellent adhesion with a resin material; and a method for producing same. The composite laminate comprises a metal substrate and one or more resin coating layers layered on the surface of the metal substrate. The resin coating layers are layered on a surface of the metal substrate that has been subjected to surface processing. At least one of the resin coating layers comprises a resin composition that contains a polyaddition-type linear macromolecule having as a constituent thereof a combination of polyaddition reactive compounds for generating a linear macromolecule. Either the combination is at least one of (1) and (2) indicated below or at least one of the resin coating layers comprises a resin composition containing a linear macromolecule that is a radical copolymer or a radical homopolymer of a monofunctional monomer having an unsaturated group. (1) A bifunctional isocyanate compound and at least one compound selected from the group consisting of bifunctional glycol compounds, bifunctional amino compounds, and bifunctional thiol compounds. (2) A bifunctional epoxy compound and at least one compound selected from the group consisting of bifunctional carboxy compounds and bifunctional thiol compounds.
