<p>An ink jet aqueous ink including an ABC triblock polymer and a polymer emulsion, wherein the above-described ABC triblock polymer is formed from an A block having a unit represented by the following general formula (1), a B block having a unit represented by the following general formula (2), and a C block having a unit represented by the following general formula (3).
in the general formula (1), R A1 represents a hydrogen atom or a methyl group and R A2 represents an alkyl group having the carbon number of 1 to 8 or a cycloalkyl group having the carbon number of 4 to 8,
in the general formula (2), R B1 represents a hydrogen atom or a methyl group and R B2 represents an alkyl group having the carbon number of 4 to 8, a cycloalkyl group having the carbon number of 4 to 8, or a hydroxy alkyl group having the carbon number of 2 to 8, and
in the general formula (3), at least one of R C1 to R C4 is a -COOH group, an -R C5 -COOH group, or a salt thereof, the remainder is a hydrogen atom, an alkyl group having the carbon number of 1 to 8, or a cycloalkyl group having the carbon number of 4 to 8, and R C5 is an alkylene group having the carbon number of 1 to 5.</p> |
