## Abstract

A durable decorative sheet high in the ability to follow a curved surface with small appearance change by heat or elongation. A decorative sheet comprising a transparent resin film having two main surfaces, a transparent resin layer formed on the first main surface of the transparent resin film, a pattern printed layer arranged on the transparent resin layer, and a colored base film arranged on the second main surface of the transparent resin film. The transparent resin layer includes first beads, the pattern printed layer include second beads. The first beads are different from the second beads in content, color and/or particle size. The first beads and the second beads are embedded in the transparent resin layer and the pattern printed layer.

## Claims

### Claim at position 1

1-12. (canceled)

### Claim 13

A thermally moldable decorative sheet comprising:
a transparent resin film having two main surfaces;
a transparent resin layer arranged on the first main surface of the transparent resin film, with first beads embedded in the transparent resin layer;
a pattern printed layer arranged on the transparent resin layer, with second beads embedded in the pattern printed layer; and
a colored base film arranged on the second main surface of the transparent resin film;
wherein the first beads are different from the second beads in content, color and/or particle size, a pattern is formed by the contrast between the transparent resin layer and the pattern printed layer, and the appearance of this contrast hardly changes when exposed to the heating and elongation of a thermal molding process.

### Claim 14 (depends on 13)

A decorative sheet as set forth in claim 13, comprising a second pattern printed layer between the second main surface of the transparent resin film and the colored base film.

### Claim 15 (depends on 13)

A decorative sheet as set forth in claim 13, comprising an adhesive layer and a release sheet in that order on the surface of the colored base film opposite to the surface thereof in contact with the transparent resin film.

### Claim 16 (depends on 14)

A decorative sheet as set forth in claim 14, comprising an adhesive layer and a release sheet in that order on the surface of the colored base film opposite to the surface thereof in contact with the transparent resin film.

### Claim 17 (depends on 14)

A decorative sheet as set forth in claim 14, wherein grooves are formed on the surface of the adhesive, in contact with the release sheet, that allow air to bleed out from behind the decorative sheet when applied to a surface.

### Claim 18 (depends on 13)

A decorative sheet as set forth in claim 13, wherein the volume ratio between the first beads and the transparent resin in the transparent resin layer is 3:3.5 to 4:5.

### Claim 19 (depends on 13)

A decorative sheet as set forth in claim 13, wherein the amount of first beads in the transparent resin layer is 21 to 85 volume percent.

### Claim 20 (depends on 13)

A decorative sheet as set forth in claim 13, wherein the volume ratio between the second beads and the resin in the pattern printed layer is 3:35 to 4:5.

### Claim 21 (depends on 18)

A decorative sheet as set forth in claim 18, wherein the volume ratio between the second beads and the resin in the pattern printed layer is 3:35 to 4:5.

### Claim 22 (depends on 19)

A decorative sheet as set forth in claim 19, wherein the volume ratio between the second beads and the resin in the pattern printed layer is 3:35 to 4:5.

### Claim 23 (depends on 13)

A decorative sheet as set forth in claim 13, wherein the pattern printed layer is embedded in the transparent resin layer.

### Claim 24 (depends on 14)

A decorative sheet as set forth in claim 14, wherein the pattern printed layer is embedded in the transparent resin layer.

### Claim 25 (depends on 15)

A decorative sheet as set forth in claim 15, wherein the pattern printed layer is embedded in the transparent resin layer.

### Claim 26 (depends on 13)

A molded part comprising the decorative sheet as set forth in claim 13.

### Claim 27 (depends on 14)

A molded part comprising the decorative sheet as set forth in claim 14.

### Claim 28 (depends on 23)

A molded part comprising the decorative sheet as set forth in claims 23.

### Claim 29 (depends on 26)

A molded part as set forth in claim 26, wherein the decorative sheet is thermally molded in a three-dimensional curved shape.

### Claim 30 (depends on 28)

A molded part as set forth in claim 28, wherein the decorative sheet is thermally molded in a three-dimensional curved shape.

### Claim 31

A method for preparing a decorative sheet, said method comprising:
forming a transparent resin layer containing first beads, on a first main surface of a transparent resin film,
embedding a pattern printed layer containing second beads into the transparent resin layer, and
forming a colored base film on a second main surface of the transparent resin film by thermally laminating the colored base film on the transparent resin film,
wherein the content, color and/or the particle size of the first beads are different from those of the second beads.

### Claim 32 (depends on 31)

A method of fabricating a decorative sheet as set forth in claim 31, wherein a second pattern printed layer is formed on a second main surface of the transparent film, and the colored base film is thermally laminated on the transparent resin film.
