Abstract

An image recording method including the steps of applying an ink containing a coloring material and anionic resin particles to a recording medium, and applying a liquid composition to the recording medium so as to at least partly overlap with an area where the ink is applied. The liquid composition destabilizes a dispersion state of the coloring material or of the anionic resin particles in the ink. The ink contains a block copolymer including a polyethylene oxide segment containing an ethylene oxide structure and a polypropylene oxide segment containing a propylene oxide structure, and the total number of the polyethylene oxide segments and the polypropylene oxide segments is 4 or more.

First claim

What is claimed is:

1 . An image recording method comprising the steps of:
applying an ink containing a coloring material and anionic resin particles to a recording medium; and applying a liquid composition to the recording medium so as to at least partly overlap with an area where the ink is applied, the liquid composition destabilizing a dispersion state of the coloring material or of the anionic resin particles in the ink, wherein the ink contains a block copolymer including a polyethylene oxide segment containing an ethylene oxide structure and a polypropylene oxide segment containing a propylene oxide structure, and the total number of the polyethylene oxide segments and the polypropylene oxide segments is 4 or more.

2 . The image recording method according to claim 1 , wherein a content of the anionic resin particles in the ink is 1.0% by mass or more based on the total mass of the ink.

3 . The image recording method according to claim 1 , wherein a content of the block copolymer is 0.6% by mass or more based on the total mass of the ink.

4 . The image recording method according to claim 1 , wherein a mass ratio of the content of the anionic resin particles relative to the content of the block copolymer based on the total mass of the ink is 0.5 or more and 25.0 or less in terms of mass ratio.

5 . The image recording method according to claim 1 , wherein the anionic resin particles comprise a polymer of a monomer composition containing at least one monomer selected from the group consisting of ester compounds of α,β-unsaturated carboxylic acids and α,β-ethylenically unsaturated compounds having an aryl group.

6 . An ink used for an image recording method, the image recording method comprising the steps of:
applying an ink containing a coloring material and anionic resin particles to a recording medium; and applying a liquid composition to the recording medium so as to at least partly overlap with an area where the ink is applied, the liquid composition destabilizing a dispersion state of the coloring material or of the anionic resin particles in the ink, wherein the ink contains a block copolymer including a polyethylene oxide segment containing an ethylene oxide structure and a polypropylene oxide segment containing a propylene oxide structure, and the total number of the polyethylene oxide segments and the polypropylene oxide segments is 4 or more.

7 . An image recording method comprising the steps of:
applying an ink containing a coloring material and anionic resin particles to a recording medium; and applying a liquid composition to the recording medium so as to at least partly overlap with an area where the ink is applied, the liquid composition destabilizing a dispersion state of the coloring material or of the anionic resin particles in the ink, wherein the liquid composition contains a block copolymer including a polyethylene oxide segment containing an ethylene oxide structure and a polypropylene oxide segment containing a propylene oxide structure, and the total number of the polyethylene oxide segments and the polypropylene oxide segments is 4 or more.

8 . The image recording method according to claim 7 , wherein a content of the block copolymer is 5.0% by mass or more based on the total mass of the liquid composition.

9 . The image recording method according to claim 7 , wherein the anionic resin particles comprise a polymer of a monomer composition containing at least one monomer selected from the group consisting of ester compounds of α,β-unsaturated carboxylic acids and α,β-ethylenically unsaturated compounds having an aryl group.

10 . A liquid composition used for an image recording method, the image recording method comprising the steps of:
applying an ink containing a coloring material and anionic resin particles to a recording medium; and applying a liquid composition to the recording medium so as to at least partly overlap with an area where the ink is applied, the liquid composition destabilizing a dispersion state of the coloring material or of the anionic resin particles in the ink, wherein the liquid composition contains a block copolymer including a polyethylene oxide segment containing an ethylene oxide structure and a polypropylene oxide segment containing a propylene oxide structure, and the total number of the polyethylene oxide segments and the polypropylene oxide segments is 4 or more.

11 . An image recording method comprising the steps of:
applying a clear ink containing anionic resin particles to a recording medium; and applying a liquid composition to the recording medium so as to at least partly overlap with an area where the clear ink is applied, the liquid composition destabilizing a dispersion state of the anionic resin particles in the clear ink, wherein the clear ink contains a block copolymer including a polyethylene oxide segment containing an ethylene oxide structure and a polypropylene oxide segment containing a propylene oxide structure, and the total number of the polyethylene oxide segments and the polypropylene oxide segments is 4 or more.

12 . A clear ink used for an image recording method, the image recording method comprising the steps of:
applying a clear ink containing anionic resin particles to a recording medium; and applying a liquid composition to the recording medium so as to at least partly overlap with an area where the clear ink is applied, the liquid composition destabilizing a dispersion state of the anionic resin particles in the clear ink, wherein the clear ink contains a block copolymer including a polyethylene oxide segment containing an ethylene oxide structure and a polypropylene oxide segment containing a propylene oxide structure, and the total number of the polyethylene oxide segments and the polypropylene oxide segments is 4 or more.
