Claims15
An article comprising:
- a wood or wood veneer substrate
- a substrate contacting layer on the wood veneer substrate, wherein the substrate contacting layer is soft and has a thickness of 25 micrometers to 125 micrometers as measured from surface of the wood veneer to the outermost surface of the substrate contacting layer, and wherein the substrate contacting layer has a pencil hardness from HB to H;
- a middle layer on the substrate contacting layer, the middle layer comprising polyurethane, wherein the middle layer is soft and has a thickness of 100 micrometers to 250 micrometers;
- and
- a top layer on the middle layer, wherein the top layer is hard, and has a thickness of 100 to 250 micrometers.
