Abstract
An ink set includes a non-white ink composition and a white ink composition, and the non-white ink composition and the white ink composition are each an aqueous ink jet ink. The non-white ink composition contains a silicone-based surfactant A having a maximum peak within a molecular weight range of 3,000 to 20,000 within a molecular weight range of 300 or more in a molecular weight distribution in gel permeation chromatography, and the white ink composition contains a silicone-based surfactant B having a HLB value of 10.5 or less by Griffin method, but not having a maximum peak within a molecular weight range of 3,000 or more within a molecular weight range of 300 or more in a molecular weight distribution in gel permeation chromatography.
