Abstract
Official abstract text for this publication.
There is provided an aqueous ink which contains a coloring agent, a polymer particle, water and an aqueous organic solvent, and a surface resistivity of a film obtained by film formation on a glass plate is 1×10 6 Ω/□ or less, and a recording method containing: a first discharge step that discharges the first aqueous ink on a front surface of a recording medium; a first drying step that dries the first aqueous ink discharged on the front surface of the recording medium after the first discharge step; and a second discharge step that discharges a second aqueous ink on a rear surface of the recording medium after the first drying step.
First claim
Opening claim text (preview).
What is claimed is: 1. An aqueous ink which comprises: a coloring agent, a polymer particle, water, and an aqueous organic solvent, wherein a surface resistivity of a film obtained by film formation on a glass plate is 1×10 6 Ω/□ or less. 2. The aqueous ink as claimed in claim 1 , wherein the polymer particle contains a polymer compound having an acid value of 10 mgKOH/g or more. 3. The aqueous ink as claimed in claim 1 , wherein the polymer particle contains a polymer compound having at least one of a sulfonic acid group and a carboxylic acid group. 4. The aqueous ink as claimed in claim 2 , wherein the polymer compound is a polyester. 5. The aqueous ink as claimed in claim 2 , wherein the polymer compound is a polyurethane.
