Abstract:
1. An inkjet recording ink, comprising: water; a wetting agent; a colorant; and polymer microparticles, wherein the polymer microparticles are each a copolymer of a monomer represented by formula (1) or formula (2), a monomer represented by formula (3), and a macromonomer represented by formula (4): where “R1” is an alkyl group comprising 1 to 4 carbon atoms, where each “R” is independently an alkyl group comprising 1 to 4 carbon atoms, where “l” is the number of repeating units, and an integer of 1 to 100, and wherein an amount of the polymer microparticles relative to a total amount of the inkjet recording ink is 0.05% by mass to 2.0% by mass as a solid content of the polymer microparticles.
