摘要

An ink for inkjet recording, which is used for recording on a paper having a concentration of an eluted Ca ion of from 1.0×10−4 to 5.0×10−4 g/g when dipped in pure water. The ink includes at least a pigment, a pigment dispersant, a water-soluble organic solvent and water. The pigment dispersant is a copolymer synthesized using at least (1) unsaturated ethylene monomer having a phosphoric acid group or a phosphonic acid group and (2) unsaturated ethylene monomer having an alkyl group having 12 to 22 carbon atoms.

1. An inkjet recording method, comprising:
applying a stimulation to an ink for inkjet recording such that the ink flies to record images on the paper having a concentration of an eluted Ca ion of from 1.0×10−4 to 5.0×10−4 g/g when dipped in pure water, wherein the ink for inkjet recording comprises: a pigment; a pigment dispersant; a water-soluble organic solvent; and water, wherein the pigment dispersant is a copolymer synthesized using at least the following monomers (1) and (2): (1) unsaturated ethylene monomer having a phosphoric acid group or a phosphonic acid group; and (2) unsaturated ethylene monomer having an alkyl group having 12 to 22 carbon atoms.
