at least one layer of the resin coating layer being formed by polyaddition reaction of a resin composition containing an in situ polymerizable phenoxy resin on the surface-treated surface of the metal base material.

2. The composite laminate according to claim 1 ,

wherein the resin coating layer includes plural layers, at least one layer of which is formed of a resin composition containing a thermosetting resin, and

the thermosetting resin is at least one selected from the group consisting of a urethane resin, an epoxy resin, a vinyl ester resin, and an unsaturated polyester resin.

3. The composite laminate according to claim 1 ,

wherein the composite laminate comprises a functional group adherent layer between the surface-treated surface of the metal base material and the resin coating layer, the functional group adherent layer is laminated in contact with the metal base material and the resin coating layer, and

the functional group adherent layer has a functional group introduced from at least one selected from the group consisting of a silane coupling agent, an isocyanate compound, and a thiol compound.

4. The composite laminate according to claim 1 , wherein the surface-treated surface is formed by a surface treatment which is at least one selected from the group consisting of a blast treatment, a grinding treatment, an etching treatment, and a chemical conversion treatment.

5. The composite laminate according to claim 4 , wherein the metal base material contains aluminum, and the surface treatment includes at least one of the etching treatment and the chemical conversion treatment, wherein the chemical conversion treatment is a boehmite treatment.

6. The composite laminate according to claim 1 , wherein the metal base material contains aluminum.
