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.

Claims

1. An ink composition containing a photocurable compound that is cured by receiving light irradiation and is dissolved by a solvent while being in a cured state, the ink composition being used for forming an ink layer on a recording medium using an inkjet scheme and removing the ink layer from the recording medium by dissolving the ink layer by the solvent after having fixed the formed ink layer by the light irradiation.

2. The ink composition according to claim 1 that is for forming the ink layer on the recording medium using the inkjet scheme and removing the ink layer from the recording medium by dissolving the ink layer by the solvent after having fixed the formed ink layer by the light irradiation, the ink layer is an image.

3. The ink composition according to claim 2 that is for forming the ink layer on the recording medium using the inkjet scheme and removing the ink layer from the recording medium by dissolving the ink layer by the solvent after having fixed the formed ink layer by the light irradiation, the ink composition further containing a chain transfer agent.

4. The ink composition according to claim 2 that is for forming the ink layer on the recording medium using the inkjet scheme and removing the ink layer from the recording medium by dissolving the ink layer by the solvent after having fixed the formed ink layer by the light irradiation, wherein the solvent for dissolving the ink composition is water, a weakly alkaline aqueous solution, or an organic solvent.

5. The ink composition according to claim 1 that is for forming the ink layer on the recording medium using the inkjet scheme and removing the ink layer from the recording medium by dissolving the ink layer by the solvent after having fixed the formed ink layer by the light irradiation, the ink layer becomes a base of an image layer.

6. The ink composition according to claim 5 that is for forming the ink layer on the recording medium using the inkjet scheme and removing the ink layer from the recording medium by dissolving the ink layer by the solvent after having fixed the formed ink layer by the light irradiation, the ink composition further containing a chain transfer agent.

7. The ink composition according to claim 5 that is for forming the ink layer on the recording medium using the inkjet scheme and removing the ink layer from the recording medium by dissolving the ink layer by the solvent after having fixed the formed ink layer by the light irradiation, wherein the solvent used for dissolving the ink composition is water, a weakly alkaline aqueous solution, or an organic solvent.

8. A method for reusing a recording medium, in which an ink 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 and is dissolved by a solvent while being in a cured state, and the ink layer is removed from the recording medium by dissolving the first ink by the solvent after having fixed the formed ink layer by the light irradiation.

9. The method for reusing a recording medium according to claim 8, in which the ink layer becomes a coating layer, an image layer is formed on the coating layer by a second ink using the inkjet scheme, and the image layer is removed from the recording medium by dissolving the coating layer by the solvent after having fixed the formed image layer by the light irradiation.

10. An ink jet recording device comprising:

a recording head that forms a coating layer on a recording medium by a first ink that is cured by receiving light irradiation and dissolved by a solvent while in a cured state, and forms an image layer on the coating layer by a second ink; and

an irradiation unit that irradiates the first ink on the recording medium with light.

11. The ink jet recording device according to claim 10, wherein the recording head forms the image layer by halftone printing.

12. The ink jet recording device according to claim 10, wherein a size of a printable range of the coating layer is larger than a size of a printable range of the image layer.

13. The ink jet recording device according to claim 11, wherein a size of a printable range of the coating layer is larger than a size of a printable range of the image layer.
