Claims12
A multi-layered finish coated product, comprising:
- an aluminum substrate comprising a 3xxx series aluminum alloy or a 5xxx series aluminum alloy, wherein the aluminum substrate comprises a beverage can end;
- a base coating layer adhered to the aluminum substrate, wherein the base coating layer has a thickness of 0.1 μm to 15 μm;
- and
- a clear coating layer comprising effects particles, wherein the clear coating layer is adhered to the base coating layer, and wherein the clear coating layer has a thickness of 1 μm to 20 μm.
