    • PROBLEM TO BE SOLVED: To provide a water-soluble rust-preventive liquid composition having good rust-preventive performance and capable of controlling rust generation even under harsh environment such as an accumulated state of metals.
      SOLUTION: The water-soluble rust-preventive liquid composition is provided by compounding, in water, (A) ≥0.001 mol/L aromatic carboxylic acid represented by general formula (1) (X)
      m -Ar-(COOH)
      n (1) [in the formula, X is NO
      2 -, RO-, or R- (wherein, R is a 1-10C hydrocarbon group), Ar is an aromatic hydrocarbon group having 2-4 direct bonds, m and n are an integer number of 1 or 2, and, when m is 2, X may be the same or different], (B) 0-1 mol/L 8-24C aliphatic carboxylic acid, and (C) at least one basic compound selected from an alkali metal hydroxide and an alkanol amine.
