Abstract

A method of transferring a foil comprising: forming a foil transferring face on a photoreceptor employing a foil transferring face forming toner; transferring the foil transferring face onto a base substance, followed by fixing the foil transferring face; supplying a transfer foil having at least a foil and an adhesive layer on the base substance having the fixed foil transferring face, heating the transfer foil and the foil transferring face while the adhesive layer of the transfer foil is in contact with the foil transferring face to adhere the foil onto the foil transferring face; removing the transfer foil from the base substance while leaving the foil adhered onto the foil transferring face, wherein the foil transferring face forming toner comprises at least a binder resin, wherein the binder resin comprises a polymer formed by using a vinyl monomer comprising at least a carboxyl group.

Claims

1. A method of transferring a foil comprising the steps of:

(1) exposing a photoreceptor to form an electrostatic latent image;

(2) supplying a foil transferring face forming toner to a photoreceptor having thereon the electrostatic latent image to form a foil transferring face on the photoreceptor;

(3) transferring the foil transferring face formed on the photoreceptor onto a base substance;

(4) fixing the foil transferring face on the base substance;

(5) supplying a transfer foil having at least a foil and an adhesive layer on the base substance having the fixed foil transferring face;

(6) bringing the adhesive layer of the transfer foil in contact with the foil transferring face;

(7) heating the transfer foil and the foil transferring face while the adhesive layer of the transfer foil is in contact with the foil transferring face to adhere the foil onto the foil transferring face; and

(8) removing the transfer foil from the base substance while leaving the foil adhered onto the foil transferring face, wherein the foil transferring face forming toner comprises at least a binder resin,

wherein the binder resin comprises;

a polymer obtained by radically polymerizing at least a methacrylic acid and a polymer obtained by radically polymerizing at least a vinyl monomer which has two or more carboxyl groups;

or

a polymer obtained by radically polymerizing at least a methacrylic acid and a vinyl monomer which has two or more carboxyl groups.

2. The method of claim 1, wherein content of the carboxyl group comprised in the binder resin is 5.0×

10<sup>−

7</sup> mol/g to 5.0×

10<sup>−

5</sup> mol/g based on a mass of the binder resin.

3. The method of claim 1, wherein the content of the carboxyl group comprised in the binder resin is 5.0×

10<sup>−

6</sup> mol/g to 5.0×

10<sup>−

5</sup> mol/g based on a mass of the binder resin.

4. The method of claim 1, wherein an amount of the foil transferring face forming toner fixed on the base substance is 2.0 to 12.0 g/m².

5. The method of claim 1, wherein the step (7) is carried out using a heat roller and a pressure roller, wherein a contact face pressure obtained by using the heat roller and the pressure roller is 200 to 600 kPa.

6. A method of forming an image comprising the steps of:

preparing a base substance provided with a foil having an image, the foil having the image being transferred according to the method of claim 1; and

forming a visible image using a toner according to an electrophotographic method on the base substance provided with the foil having the image to manufacture a product having both the foil having the image and the visible image.
