Abstract

Official abstract text for this publication.

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 polyamine compound having a group formed by substituting a hydrogen atom of an amino group by a structure represented by —Rn n —H, where R is an alkyleneoxy group including an ethyleneoxy group, and the number of Rs per molecule is 5 or more and 180 or less.

First claim

Opening claim text (preview).

What is claimed is: 1. An image recording method comprising the steps of: applying an ink comprising 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 comprises a polyamine compound having a group formed by substituting a hydrogen atom of an amino 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 5 or more and 180 or less. 2. The image recording method according to claim 1 , wherein a content of the anionic resin particles in the ink is 1% 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 polyamine 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 ratio of the content of the anionic resin particles relative to the content of the polyamine compound based on the total mass of the ink is 0.5 times or more and 25.0 times 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 that comprises the steps of applying the ink 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 a coloring material or of anionic resin particles in the ink, the ink comprising: a coloring material and anionic resin particles; and a polyamine compound having a group formed by substituting a hydrogen atom of an amino 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 5 or more and 180 or less. 7. An image recording method comprising the steps of: applying an ink comprising 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 comprises a polyamine compound having a group formed by substituting a hydrogen atom of an amino 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 5 or more and 180 or less. 8. The image recording method according to claim 7 , wherein a content of the polyamine compound 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 that comprises the steps of applying an ink comprising 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, the liquid composition comprising: a polyamine compound having a group formed by substituting a hydrogen atom of an amino 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 5 or more and 180 or less. 11. An image recording method comprising the steps of: applying a clear ink comprising 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, wherein the clear ink comprises a polyamine compound having a group formed by substituting a hydrogen atom of an amino 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 5 or more and 180 or less. 12. A clear ink used for an image recording method that comprises the steps of applying the clear ink 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 anionic resin particles in the clear ink, the clear ink comprising: anionic resin particles; and a polyamine compound having a group formed by substituting a hydrogen atom of an amino 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 5 or more and 180 or less. 13. The image recording method according to claim 1 , wherein the anionic resin particles are present in the state of particles having a particle size and dispersed in a solvent. 14. The image recording method according to claim 1 , wherein the anionic resin particles have a 50% cumulative volume average particle diameter (D 50 ) of 10 nm or more and 1,000 nm or less. 15.
