Abstract

A dyeing base body to be used in a dyeing step of dyeing a resin body by heating a sublimable dye attached to the dyeing base body by electromagnetic waves to sublime the dye toward the resin body. The dyeing base body includes a metal base made in sheet form and an electromagnetic wave absorption layer formed on at least an opposite side to the side to which the dye will be attached. The electromagnetic wave absorption layer has a higher electromagnetic wave absorption rate than the base.

First claim

What is claimed is:

1. A method for producing a dyed resin body, including:
placing a dyeing base body comprising a surface on which a sublimable dye is attached under a vacuum, the dyeing base body including a metal base made in sheet form and an electromagnetic wave absorption layer having a higher electromagnetic wave absorption rate than the base;
irradiating electromagnetic waves toward the electromagnetic wave absorption layer of the dyeing base body to heat the dye, thereby causing the dye to sublime and be deposited on a resin body that opposes the surface of the dyeing base body on which the dye is attached; and
heating the resin body on which the dye has been deposited to fix the dye to the resin body.

2. A method for producing a dyeing base body, the method including:
forming a dye layer containing a dye on a base body including a metal base made in sheet form and an electromagnetic wave absorption layer, the electromagnetic wave absorption layer having a higher electromagnetic wave absorption rate than the base,
wherein the dye layer is formed on a surface of the base, and the electromagnetic wave absorption layer is disposed on at least a surface of the base that is opposite to the surface of the base on which the dye layer is formed.

3. A dyeing base body comprising:
a metal base made in sheet form; and
an electromagnetic wave absorption layer having a higher electromagnetic wave absorption rate than the base;
wherein:
a surface of the base is configured to hold a dye layer containing a sublimable dye;
the electromagnetic wave absorption layer is formed on at least a surface of the base that is opposite to the surface of the base that is configured to hold the dye layer; and
the dye is configured to be sublimed by heating via electromagnetic waves and deposited on a resin body.

4. A dyeing base body comprising:
a metal base made in sheet form;
an electromagnetic wave absorption layer having a higher electromagnetic wave absorption rate than the base; and
a dye holding layer configured to hold a sublimable dye and formed on a surface of the base;
wherein:
the electromagnetic wave absorption layer is formed on at least a surface of the base that is opposite to the surface of the base on which the dye holding layer is formed; and
the dye is configured to be sublimed by heating via electromagnetic waves and deposited on a resin body.

5. The dyeing base body according to claim 4 , wherein the dye holding layer comprises a hydrophilic macromolecule material.

6. The dyeing base body according to claim 5 , wherein the hydrophilic macromolecule material comprises at least one of polyethylene oxide, polyethylene glycol, polyvinyl pyrrolidone, polyvinyl alcohol, and a copolymer of polyvinyl pyrrolidone and vinyl acetate.

7. The dyeing base body according to claim 4 , further comprising a coloring material; wherein:
the coloring material is in a layer interposed between the base and the dye holding layer, or is in the dye holding layer; and
the coloring material has a different color than the base.

8. The dyeing base body according to claim 4 , wherein the base has a thickness of 1 μm or more and 1,000 μm or less.

9. The dyeing base body according to claim 4 , wherein a material of the electromagnetic wave absorption layer comprises a black or dark color pigment and a heat resistant resin material.

10. The dyeing base body according to claim 4 , wherein the electromagnetic wave absorption layer is formed in a region occupying a part of one surface of the dyeing base body and covering a back side of a region to which the dye is to be attached.
