ABSTRACT:
The present invention relates to an aqueous ink for ink jet recording and a water dispersion for ink jet recording, including water-insoluble vinyl polymer particles containing a colorant, the water-insoluble vinyl polymer being a water-insoluble vinyl polymer obtained by polymerizing a monomer mixture of:(A) a monomer represented by the formula (I):wherein R1represents a hydrogen atom or a lower alkyl group, R2represents an alkylene group having 2 to 18 carbon atoms or an alkylene group having 2 to 4 carbon atoms in which a phenyl group is substituted for a hydrogen atom thereof, n denotes a number from 2 to 30 and R3represents a straight or branched alkyl group having 8 to 30 carbon atoms;(B) a monomer containing a salt-forming monomer; and (C) a hydrophobic monomer.
