## Abstract

A disclosed method for manufacturing a floor covering includes the steps of vulcanising a support layer made of an elastomer and assembling an intermediate layer to the support layer during the step of vulcanising, wherein the intermediate layer is made of a material selected from the group that includes polyester, polyetheretherketone, polyetherimide, polysulfone, polyimide, polyamide, fluoropolymer, polyurethane, and paper. A print layer is printed either the intermediate layer or a transparent protective layer. When the print layer is printed on the intermediate layer, the protective layer is assembled to the print layer of a set that includes the print layer, the intermediate layer, and the support layer. When the print layer is printed on the protective layer, the print layer of a set that includes the print layer and the protective layer is assembled to the intermediate layer of a set that includes the intermediate layer and the support layer.

## Claims

### Claim 1

A floor covering, comprising:
a protective layer that is transparent;
a print layer comprising of an ink layer;
an intermediate layer made of a material selected from the group consisting of polyester, polyetheretherketone, polyetherimide, polysulfone, polyimide, polyamide, fluoropolymer, and polyurethane;
a print layer comprising of an ink layer printed on the intermediate layer; and
a support layer made of an elastomer,
wherein the intermediate layer and the support layer are bonded to each other by crosslinks.

### Claim 2 (depends on 1)

The floor covering according to claim 1, wherein the intermediate layer is made of polyester.

### Claim 3 (depends on 1)

The floor covering according to claim 1, wherein the intermediate layer and the support layer are assembled during vulcanisation of the elastomer of the support layer.

### Claim 4 (depends on 1)

The floor covering according to claim 1, wherein the print layer comprises an ink layer printed on the intermediate layer.

### Claim 5 (depends on 4)

The floor covering according to claim 4, wherein the print layer is disposed between the intermediate layer and the protective layer.

### Claim 6 (depends on 1)

The floor covering according to claim 1, wherein the print layer comprises an ink layer printed on the protective layer.

### Claim 7 (depends on 1)

The floor covering according to claim 1, wherein the intermediate layer is one of woven, non-woven, and in film form.
