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 destabilizing a dispersion state of the coloring material or of the anionic resin particles in the ink. The ink contains a trihydric or higher polyhydric alcohol compound having a group formed by substituting a hydrogen atom of a hydroxyl group by a structure represented by —R n —H, where R is an alkyleneoxy group including an ethyleneoxy group, and the number of Rs per molecule is 40 or more and 120 or less when the polyhydric alcohol is a trihydric alcohol and is 12 or more and 400 or less when the polyhydric alcohol is a tetrahydric or higher polyhydric alcohol.

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 trihydric or higher polyhydric alcohol compound having a group formed by substituting a hydrogen atom of a hydroxyl group by a structure represented by —R n —H, where R is an alkyleneoxy group including an ethyleneoxy group; and the number of Rs per molecule is 40 or more and 120 or less when the polyhydric alcohol is a trihydric alcohol and is 12 or more and 400 or less when the polyhydric alcohol is a tetrahydric or higher polyhydric alcohol.

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 polyhydric alcohol compound 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 polyhydric alcohol compound 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 the 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 trihydric or higher polyhydric alcohol compound having a group formed by substituting a hydrogen atom of a hydroxyl group by a structure represented by —R n —H, where R is an alkyleneoxy group including an ethyleneoxy group; and the number of Rs per molecule is 40 or more and 120 or less when the polyhydric alcohol is a trihydric alcohol and is 12 or more and 400 or less when the polyhydric alcohol is a tetrahydric or higher polyhydric alcohol.

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 trihydric or higher polyhydric alcohol compound having a group formed by substituting a hydrogen atom of a hydroxyl group by a structure represented by —R n —H, where R is an alkyleneoxy group including an ethyleneoxy group; and the number of Rs per molecule is 40 or more and 120 or less when the polyhydric alcohol is a trihydric alcohol and is 12 or more and 400 or less when the polyhydric alcohol is a tetrahydric or higher polyhydric alcohol.

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

9 . 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 the 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 trihydric or higher polyhydric alcohol compound having a group formed by substituting a hydrogen atom of a hydroxyl group by a structure represented by —R n —H, where R is an alkyleneoxy group including an ethyleneoxy group; and the number of Rs per molecule is 40 or more and 120 or less when the polyhydric alcohol is a trihydric alcohol and is 12 or more and 400 or less when the polyhydric alcohol is a tetrahydric or higher polyhydric alcohol.

10 . The image recording method according to claim 7 , wherein the anionic resin particles are 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.

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 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, where the clear ink contains a trihydric or higher polyhydric alcohol compound having a group formed by substituting a hydrogen atom of a hydroxyl group by a structure represented by —R n —H, where R is an alkyleneoxy group including an ethyleneoxy group; and the number of Rs per molecule is 40 or more and 120 or less when the polyhydric alcohol is a trihydric alcohol and is 12 or more and 400 or less when the polyhydric alcohol is a tetrahydric or higher polyhydric alcohol.

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 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, where the clear ink contains a trihydric or higher polyhydric alcohol compound having a group formed by substituting a hydrogen atom of a hydroxyl group by a structure represented by —R n —H, where R is an alkyleneoxy group including an ethyleneoxy group; and the number of Rs per molecule is 40 or more and 120 or less when the polyhydric alcohol is a trihydric alcohol and is 12 or more and 400 or less when the polyhydric alcohol is a tetrahydric or higher polyhydric alcohol.
