The present invention may provide an adhesive composition comprising lysine, itaconic acid and water, wherein the lysine and itaconic acid are in the form of aqueous salt solutions, and precipitates thereof are not formed in the aqueous solutions. In addition, the present invention may provide a method for preparing an adhesive composition, the method comprising the steps of: mixing lysine, itaconic acid and water; and stirring the mixture at 80°C or lower, wherein the lysine, itaconic acid and water content in the adhesive composition is controlled so as to prevent precipitates of the lysine and itaconic acid from forming. |
