## Abstract

The present disclosure relates to a decorative panel with a carrier plate comprising a multi-laminate plastic carrier material with a plurality N of layer sequences of the A-B-A type, wherein layer A comprises a first thermoplastic resin and layer B a second thermoplastic resin different from the thermoplastic resin of layer A and wherein N lies between ≥3 and ≤250.

## Claims

### Claim 1

A carrier plate, for a decorative panel, the carrier plate comprising a multi-laminate layer structure with a plurality N of layer sequences of the A-B-A type, wherein layer A comprises a first thermoplastic resin and layer B a second thermoplastic resin different from the thermoplastic resin of layer A and wherein N lies between ≥3 and ≤≥50, wherein layer B at least comprises a filler apart from the thermoplastic resin, wherein the filler is selected from the group comprising chalk, non-asbestos silicate, magnesium silicate, wood dust, expanded clay, volcanic ash, pumice, cellular concrete, inorganic foams, cellulose or a blowing agent and wherein the proportion of filler lies in a range between ≥1 wt.-% and ≤60 wt.-% related to the total mass of material forming layer B, wherein layer sequence A-B-A has in total a layer thickness between 100 μm and 2000 μm.

### Claim 2 (depends on 1)

The carrier plate according to claim 1, wherein the thermoplastic resin of layer B comprises an amorphous thermoplastic resin.

### Claim 3 (depends on 2)

The carrier plate according to claim 2, wherein the proportion of amorphous thermoplastic resin in layer B lies in a range between ≥10 wt.-% and ≤100 wt.-% related to the polymer proportion of layer B.

### Claim 4 (depends on 1)

The carrier plate according to claim 1, wherein the thermoplastic resin of layer A comprises a glycol-modified polyethylene terephthalate (PET-G).

### Claim 5 (depends on 4)

The carrier plate according to claim 4, wherein the proportion of glycol-modified polyethylene terephthalate lies in a range between ≥2 wt.-% and ≤10 wt.-% related to the thermoplastic resin of layer A.

### Claim 6 (depends on 1)

The carrier plated according to claim 1, wherein the layer thickness of layer B amounts to between 100% and 3000% of the layer thickness of layer A.
