    • PROBLEM TO BE SOLVED: To provide an ink set for ink-jet recording suppressing adhesion and deposition of a coagulation body, excellent in removal property of the deposited coagulation body and capable of attaining image formation of high resolution by suppressing generation of image failure such as voids. SOLUTION: The ink set for ink-jet recording contains a water-based ink composition containing a pigment covered by a copolymer containing a repetition unit (a) represented by general formula (1) and a repetition unit (b) having an ionic group, an organic solvent, a neutralization agent and water, and a water-based liquid composition containing a component for coagulating the pigment in the water-based ink composition when it is mixed with the water-based ink composition. Wherein R 1 represents a hydrogen atom or a methyl group, L 1 represents a phenylene group, L 2 represents a single bond or a divalent connection group, and Ar represents a monovalent group derived from a 8 or more C ring-condensed aromatic ring, a hetero-ring having the ring-condensed aromatic ring or two or more-connected benzene ring.
