Abstract
A reaction liquid containing a reactive substance that reacts with at least one component in an ink composition containing a coloring material in a dispersed state, in which the reactive substance is a polyvalent metal compound having multiple reactive sites in one molecule, a set of ink and a reaction liquid, and an image recording method for performing image recording by means of the set.
Claims9
A reaction liquid comprising a reactive substance that reacts with at least one component in an ink composition comprising a coloring material in a dispersed state,
- wherein the reactive substance is a polyvalent metal compound having multiple reactive sites in one molecule.
A set of an ink composition and a reaction liquid, comprising:
- an ink composition comprising a coloring material in a dispersed state;
- and
- a reaction liquid comprising a reactive substance that reacts with at least one component in the ink composition,
- wherein the reactive substance is a polyvalent metal compound having multiple reactive sites in one molecule.
An image recording method of recording an image by applying, to a recording medium, a set of an ink composition and a reaction liquid, the set comprising an ink composition comprising a coloring material in a dispersed state and a reaction liquid comprising a reactive substance that reacts with at least one component in the ink composition,
- wherein the reactive substance is a polyvalent metal compound having multiple reactive sites in one molecule,
- wherein the image recording method comprising the steps of:
- (i) applying the ink composition constituting the set of the ink composition and the reaction liquid to the recording medium by means of an ink-jet method;
- and
- (ii) applying the reaction liquid constituting the set of the ink composition and the reaction liquid to the recording medium,
- wherein the steps (i) and (ii) are performed in such a manner that the ink composition and the reaction liquid contact with each other on the recording medium.
A set of an ink composition and a reaction liquid, comprising:
- an ink composition comprising a coloring material in a dispersed state;
- and
- a reaction liquid comprising a reactive substance that reacts with at least one component in the ink composition,
- wherein the reactive substance is a polyvalent metal compound having multiple reactive sites in one molecule;
- and
- wherein when defining a flocculation value as a ratio of a height of an aggregate to a height from a bottom surface of a vessel having an inner diameter of 10 mm to a liquid level after 5 g of the reaction liquid 100-times diluted with water are charged into the vessel, 0.25 g of the ink composition is added dropwise to the vessel, and the whole is left standing for 60 minutes, the flocculation value is less than 0.5.
