Abstract

A method may be provided for manufacturing a floor panel having a decorative upper side formed by a top layer. The top layer may have at least a decorative layer that includes a digital print and a transparent or translucent wear layer. The method may involve providing a plurality of pigmented liquid inks. The pigmented liquid inks may include a first binding agent. A film may be provided. The digital print may be provided on the film by jetting one or more of the pigmented liquid inks onto the film using a digital inkjet printer. A second binding agent may be provided on the top of the digital print or the bottom of the translucent or transparent wear layer. The film and the transparent or translucent wear layer may be laminated such that the digital print is in between the film and the transparent or translucent wear layer, and the second binding agent is between the digital print and the bottom of the transparent or translucent wear layer.

Claims (21)

1. A method for manufacturing a floor panel having a decorative upper side formed by a top layer, the top layer having at least a decorative layer that includes a digital print and a transparent or translucent wear layer, the method comprising:

providing a plurality of pigmented liquid inks, wherein the pigmented liquid inks include a first binding agent;

providing a film;

providing the digital print on the film by jetting one or more of the pigmented liquid inks onto the film using a digital inkjet printer;

providing a second binding agent on the digital print or the translucent or transparent wear layer;

laminating the film and the transparent or translucent wear layer such that the digital print is in between the film and the transparent or translucent wear layer, and the second binding agent is between the digital print and the transparent or translucent wear layer.

2. The method of claim 1 , wherein the first binding agent and the second binding agent are the same chemical substance.

3. The method of claim 1 , wherein the first binding agent and/or the second binding agent comprise VC-VAC.

4. The method of claim 1 , wherein the second binding agent is applied in an amount of 10 to 60 grams wet weight per square meter.

5. The method of claim 1 , wherein the second binding agent has a dry matter content of 30 percent by weight or more.

6. The method of claim 1 , wherein the film is a white or uniformly colored film.

7. The method of claim 6 , wherein the film is a thermoplastic film.

8. The method of claim 7 , wherein the film is a PVC film.

9. The method of claim 8 , wherein the PVC film includes less than 10% of plasticizer.

10. The method of claim 1 , wherein the pigmented liquid inks comprise an amount of the first binding agent of at least 2 percent by weight of the respective pigmented liquid ink.

11. The method of claim 10 , wherein the pigmented liquid inks comprise an amount of the first binding agent less than 20 percent by weight of the respective pigmented liquid ink.

12. The method of claim 1 , wherein the pigmented liquid inks comprise an amount of the first binding agent between 2 and 20 percent by weight of the respective pigmented liquid ink;

wherein the second binding agent is applied in an amount of 10 to 60 grams wet weight per square meter with a dry matter content of at least 30 percent by weight; and

wherein the first binding agent and/or the second binding agent include VC-VAC.

13. The method of claim 1 , wherein the pigmented liquid inks are water-based inks.

14. The method of claim 1 , wherein the translucent or transparent wear layer is a PVC film having a thickness of 150 micrometers or more.
