Abstract

A design transfer sheet of one embodiment of the present disclosure contains a release layer and a design transfer layer releasably mounted on the release layer, and the design transfer layer contains a thermally adherable first surface layer and a thermally adherable second surface layer in that order from the release layer side.

First claim

What is claimed is:

1. A design transfer sheet comprising:
a release layer; and
a design transfer layer releasably mounted on the release layer,
with the design transfer layer including a thermally adherable first surface layer and a thermally adherable second surface layer in that order from the release layer side,
wherein the first surface layer or the second surface layer or both has a design, or a design layer is disposed between the first surface layer and the second surface layer, and wherein at least one of the first surface layer and the second surface layer contains phenoxy resin and polyurethane, wherein the polyurethane has a glass transition temperature of not greater than 40° C.

2. The design transfer sheet according to claim 1 , wherein at least one of the first surface layer and the second surface layer contains at least one thermoplastic resin selected from the group consisting of vinyl chloride/vinyl acetate copolymer, polyurethane, polyester, (meth)acrylic resin and phenoxy resin.

3. The design transfer sheet according to claim 1 , wherein the polyurethane is polyester-based polyurethane.

4. The design transfer sheet according to claim 1 , wherein the mass ratio of the phenoxy resin and the polyurethane is from 99:1 to 30:70.

5. A decorative film comprising:
the design transfer layer described in claim 1 ;
a metal brightening layer;
a substrate layer disposed on the side of either the first surface layer or the second surface layer of the design transfer layer; and an outermost layer disposed on the outermost surface on the side of the other of the first surface layer or the second surface layer of the design transfer layer; of the first surface layer and the second surface layer of the design transfer layer, the layer that contains phenoxy resin being adjacent to the metal brightening layer.

6. A decorative film comprising: a design transfer layer comprising a thermally adherable first surface layer and a thermally adherable second surface layer, wherein the first surface layer or the second surface layer or both has a design, or a design layer is disposed between the first surface layer and the second surface layer; a substrate layer disposed on the side of either the first surface layer or the second surface layer of the design transfer layer; and an outermost layer disposed on the outermost surface on the side of the other of the first surface layer or the second surface layer of the design transfer layer, wherein the outermost layer comprises an acrylic resin, fluorine resin, polyvinyl chloride, polyurethane, polyolefin, or a copolymer or ionomer thereof, and wherein the outermost layer is capable of being processed by deep drawing.
