    • PROBLEM TO BE SOLVED: To provide a liquid composition which can form an image with excellent glossiness and image clarity, using a colored ink jointly, in an inkjet recording method. SOLUTION: This liquid composition is used together with the colored ink and imparted to a recording medium. In addition, the liquid composition contains water, a water-soluble solvent and a block copolymer, and does not contain a colorant. The water-soluble solvent is at least, one kind of water-soluble solvent selected from the specific classification. Further, the content (A) of the water-soluble solvent is 2 mass% to 8 mass%, and the block copolymer is a copolymer which is selected from the specific classification and has an acid value of 150 mgKOH/g to 250 mgKOH/g. Besides, the content (B) of the block copolymer is 2 mass% to 4 mass%, and the ratio (A/B) of the content (A) of the water-soluble solvent to the content (B) of the block copolymer, is 1 to 2.
