Abstract:
1. An ink-jet recording ink set comprising at least one first liquid A for at least forming an image and at least one second liquid B having a different composition from the composition of the first liquid A, wherein the first liquid A contains at least a polymer having a heterocyclic residue for forming a colorant, and a pigment, a sp value of the second liquid B is 35 or less and the difference of the sp value between the first liquid A and the second liquid B is 10 or less, the polymer contains a repeating unit represented by formula (1): wherein, in the formula, R represents a hydrogen atom or methyl group; J represents —CO—, —COO—, —CONR the second liquid B further contains a lipophilic solvent, and the content of the lipophilic solvent is 50% by mass or more of the total mass of the second liquid B, the lipophilic solvent is a high boiling point organic solvent having a boiling point higher than 100° C., the ink set is an ultraviolet light curable ink set, and the high boiling point organic solvent is a compound represented by one of the formulae [S-1] to [S-9]: wherein: in formula [S-1], R in formula [S-2], R in formula [S-3], Ar represents an aryl group, e represents an integer of 1 to 6, and R in formula [S-4], R in formula [S-5], g represents an integer of 2 to 6, R in formula [S-6], R in formula [S-7], R in formula [S-8], R in formula [S-9], R
