Image recording method, ink, and liquid composition
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.
1. An ink comprising:
(a) a coloring material;
(b) anionic resin particles; and
(c) a pentahydric or higher and a dodecahydric or lower 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 “R”s per molecule is 40 or more and 400 or less.
2. The ink according to claim 1 , wherein the R is the alkyleneoxy group including the ethyleneoxy group and a propyreneoxy group.
3. The ink according to claim 1 , wherein, in the structure represented by —R n —H, the n is 2.0 to 66.7.
4. The ink according to claim 1 , wherein a content of the anionic resin particles is 1.0% by mass or more based on the total mass of the ink.
5. The ink according to claim 1 , wherein a content of the pentahydric or higher and the dodecahydric or lower polyhydric alcohol compound is 0.6% by mass or more based on the total mass of the ink.
6. The ink according to claim 5 , wherein the content of the pentahydric or higher and the dodecahydric or lower polyhydric alcohol compound is 0.6% by mass or more and 10.0% by mass or less based on the total mass of the ink.
7. The ink according to claim 1 , wherein a mass ratio of the content of the anionic resin particles relative to the content of the pentahydric or higher and the dodecahydric or lower polyhydric alcohol compound based on the total mass of the ink is 0.5 or more and 25.0 or less.
8. The ink according to claim 1 , wherein the anionic resin particles comprise a polymer of a monomer composition comprising 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.
9. The ink according to claim 1 , wherein the coloring material is a pigment.
10. The ink according to claim 1 , further comprising water, wherein a content of the water is 50.0% by mass or more and 95.0% by mass or less based on the total mass of the ink.
11. The ink according to claim 1 , wherein the pentahydric or higher and the dodecahydric or lower polyhydric alcohol compound is represented by the following general formula A, B, or C:
wherein, in general formula A, m is 3 to 4;
general formula B:
wherein, in general formula C, m is 3 to 10.
12. The ink according to claim 11 , wherein, in general formula C, m is 4 to 10.
