Abstract
A main object of the present invention is to provide an ink composition for ink-jet recording capable of forming an ink film excellent in both film strength and scratch resistance. The present invention achieves the object by providing an ink composition for ink-jet recording comprising: an aqueous solvent including water and water-soluble organic solvent; a coloring agent; a resin emulsion; and a surfactant; wherein the resin emulsion includes a silicon-acrylic resin emulsion and a resin emulsion other than the silicon-acrylic resin emulsion; a content ratio of the resin emulsion to the coloring agent (content of the resin emulsion/content of the coloring agent) is 1/5 or more and 15/1 or less; and a content ratio of the silicon-acrylic resin emulsion to the coloring agent (content of the silicon-acrylic resin emulsion/content of the coloring agent) is 1/20 or more and 5/1 or less.
