## Abstract

The invention relates to a self-adhesive floor without release paper and the production method thereof. The self-adhesive floor without release paper includes a top coating layer, a substrate layer and a self-adhesive layer which are layered in sequence, wherein the said top coating layer prevents sticking. In the invention, the self-adhesive floor is free of release paper. The top coating layer can prevent sticking just like release paper, which can prevent the products from sticking to each other and protect the self-adhesive layer. The top layer includes both release material and ultra violet (UV) paint.

## Claims

### Claim 1

A self-adhesive flooring comprising a top coating layer, a substrate layer and a bottom self-adhesive layer which are sequentially layered, wherein the top coating layer has release material to prevent sticking.

### Claim 2 (depends on 1)

The self-adhesive flooring according to claim 1, wherein the said top coating layer is one layer which includes a mixture of release material and UV paint.

### Claim 3 (depends on 1)

The self-adhesive flooring according to claim 1, wherein the said top coating is two layers, one layer is a release material layer and a second layer is a UV paint layer.

### Claim 4 (depends on 1)

The self-adhesive flooring according to claim 1 wherein the surface of the substrate layer has a flat or deep emboss.

### Claim 5 (depends on 1)

The self-adhesive flooring according to claim 1, wherein the self-adhesive layer is monolayer or multilayer structure which can affix the self-adhesive floor to the ground.

### Claim 6

A method of producing the self-adhesive flooring comprising the steps without release paper includes:
a. preparing a substrate layer having a top surface and a bottom surface;
b. adding a top coating layer on the top surface of the substrate layer by spraying, rolling or scraping;
c. adding the self-adhesive layer to a bottom surface of the substrate layer.

### Claim 7 (depends on 6)

The method of producing the self-adhesive flooring according to claim 6, wherein the top layer is one layer which includes a mixture of release material and UV paint, and having a coating weight is 0.2-150 g/m2.

### Claim 8 (depends on 6)

The method of producing the self-adhesive flooring according to claim 6, wherein the said top layer has two layers, one layer is a release material layer and a second layer is a UV paint layer, the coating weight is 0.2-150 g/m2.

### Claim 9 (depends on 6)

The method of producing the self-adhesive floor without release paper according to claim 6, wherein flat or deep emboss is formed on the top surface of the said substrate layer using an embossment board.

### Claim 10 (depends on 6)

The method of producing the self-adhesive flooring according to claim 6, wherein the self-adhesive layer is monolayer or multilayer structure which can affix the self-adhesive flooring to the ground.
