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.
