<P>PROBLEM TO BE SOLVED: To provide an ink-jet ink set and an ink-jet recording image forming method using the ink-jet ink set that can form a high-definition image having high scratch resistance and excelling in failure resistance, sharpness and granularity, on a water non-absorptive recording medium or a low water absorptive recording medium. <P>SOLUTION: The ink-jet ink set is composed of a water-based pigment ink containing fixing resin and a water-soluble solvent, and a water-based processing liquid containing at least organic acid. The fixing resin contained in the water-based pigment ink is a water-soluble copolymer obtained by carrying out neutralizing dissolution of a copolymer polymerized with unsaturated vinyl having a carboxyl group as a monomer component, using amine, and water dispersion type resin particles. The water-soluble solvent contained in the water-based pigment ink is glycol ether or 1,2-alkanediols, and the water-based processing liquid contains nonionic water dispersion type resin particles. <P>COPYRIGHT: (C)2010,JPO&INPIT |
