Ink composition, ink jet recording device, ink jet recording method, and method for reusing recording medium
First Claim
1. A method for reusing a recording medium, in which the recording medium is reused while an image formed on the recording medium is removed, wherein:
- a coating layer is formed using an inkjet scheme on the recording medium by using a first ink containing a photocurable compound that is cured by receiving light irradiation,an image layer is formed on the coating layer by a second ink which is not dissolved by a solvent using an inkjet scheme,the image layer is removed from the recording medium by dissolving the coating layer by the solvent after having cured the coating layer,the first ink further contains a chain transfer agent which suppresses a molecular weight of a polymer of the photocurable compound, andthe image layer is formed by halftone printing the second ink.

Abstract
Recordation and removal of an image that can be removed from a recording medium are facilitated with suitable workability.
An ink composition for forming an image using an ink jet scheme on a recording medium, and removing the image from the recording medium by dissolving the image by a solvent after having fixed the formed image by light irradiation, and an ink composition that is to become a base of an image layer formed on the recording medium using the ink jet scheme, and that is for removing the image layer from the recording medium by dissolving the ink composition by the solvent after having fixed the formed image layer by the light irradiation that are according to the present disclosure include a photocurable compound that is cured by receiving light irradiation and dissolved by a solvent while in a cured state.

3. An ink jet recording device, which uses an ink that is dissolved by a solvent after curing, and contains a chain transfer agent which suppresses a molecular weight of a polymer of the photocurable compound as a first ink, comprising:
-
a recording head that forms a coating layer on a recording medium by the first ink that is cured by receiving light irradiation, and after curing the first ink, forms an image layer on the coating layer by a second ink that is not dissolved by a solvent; and an irradiation unit that irradiates the first ink on the recording medium with light, wherein the recording head forms the image layer by halftone printing. - View Dependent Claims (4, 5, 6)
