Abstract
Disclosed herein is a water-based ink for ink-jet, comprising a liquid composition containing a coloring material and a liquid medium, wherein the ink comprises a polymer exhibiting a heat-reversible type thickening property and a compound having a light-heat converting function, or a polymer which exhibits a heat-reversible type thickening property and has a moiety capable of undergoing light-heat conversion.
Claims38
A water-based ink for ink-jet recording, containing a coloring material, a liquid medium, a polymer exhibiting a heat-reversible thickening property, and a compound having a light-to-heat converting function, wherein when the ink is exposed to visible light, the compound generates heat sufficient to cause the polymer to aggregate, thereby to increase a viscosity of the ink.
A water-based ink for ink-jet recording, containing a coloring material, a liquid medium, and a polymer which exhibits a heat-reversible thickening property and which has a functional group that undergoes light-to-heat conversion which, when the ink is exposed to visible light, generates heat sufficient to cause the polymer to aggregate, thereby to increase a viscosity of the ink.
