Laminated wood polymer composite article and method of making a laminated wood polymer composite article

1. A laminated composite article comprising:

a core component, the core component being a wood polymer composite component;

a laminate sheet disposed overlying at least a portion of the core component, the laminate sheet comprising:

an acrylic wear layer;

a polyurethane tie layer underlying the wear layer;

an ink layer underlying the polyurethane tie layer;

an acrylic or polyvinylchloride print substrate underlying the ink layer, the print substrate being a different composition than the wear layer; and

a polyurethane adhesive underlying the print substrate, the polyurethane adhesive being a different composition than the polyurethane tie layer;

wherein the laminate sheet comprises UV absorbers, the UV absorbers being arranged and disposed to provide ink stability to the ink layer;

wherein the wear layer comprises the UV absorbers in sufficient concentration to reduce or eliminate change in physical appearance of the laminated composite article.

2. The laminated composite article of claim 1 , wherein polyurethane adhesive underlying the print substrate is an adhesive layer disposed between the laminate sheet and the core component.

3. The laminated composite article of claim 1 , wherein the core component includes a coextruded wood polymer composite composition, wherein at least one coextruded layer comprises virgin or clean polyethylene material.

4. The laminated composite article of claim 1 , wherein the wear layer further comprises an additional coating layer disposed on the acrylic layer selected from the group consisting of a polyvinyldinefluoride-containing layer, a hard coat layer, a rigid acrylic layer, and combinations thereof.

5. The laminated composite article of claim 4 , wherein the additional layer includes inorganic, organic fillers or nanofillers.

6. The laminated composite article of claim 1 , wherein the wear layer includes a coating layer selected from the group consisting of a polyurethane layer, an ionomer layer, thermoplastic polyurethane layer, and combinations thereof.

7. The laminated composite article of claim 6 , wherein the wear layer further comprises a hard coat layer on the coating layer.

8. The laminated composite article of claim 7 , wherein the hard coat layer includes inorganic, organic fillers or nanofillers.

9. The laminated composite article of claim 6 , wherein the wear layer further comprises a tie layer between the coating layer and the ink layer.

10. The laminated composite article of claim 6 , wherein the laminated composite article further includes a printable film between the adhesive, the ink layer and the adhesive layer.

11. The laminated composite article of claim 10 , wherein the printable film comprises a layer selected from the group consisting of acrylic film, polyester film, polyvinyl chloride (PVC) film, thermoplastic polyurethane film, polyethylene (PE) film and combinations thereof.

12. A laminated composite article comprising:

a core component, the core component being a wood polymer composite component;

a laminate sheet disposed overlying at least a portion of the core component, the laminate sheet comprising:

an acrylic wear layer;

a polyurethane tie layer underlying the wear layer;

an ink layer underlying the polyurethane tie layer;

an acrylic or polyvinylchloride print substrate underlying the ink layer, the print substrate being a different composition than the wear layer; and

a polyurethane adhesive underlying the print substrate, the polyurethane adhesive being a different composition than the polyurethane tie layer;

wherein the laminate sheet comprises UV absorbers, the UV absorbers being arranged and disposed to provide ink stability to the ink layer;

wherein the laminated composite article resists a change in visual appearance for a period of at least 5 years.
