PURPOSE: A retention label for blocking the infusion of ink is provided, to minimize the generation of floating material due to the ink contained in the label when it is dipped in NaOH solution and the label is removed. CONSTITUTION: The retention label comprises an adhesion part(120) which is made of pulp and the evaporated and deposited aluminium; the first intermediation part(122) which is placed on the adhesion part and intermediates the adhesion of the metal material on the adhesion part; a metal part(124) which is placed on the first intermediation part, and made of a metal, and whose appearance is visually contrast to the ink displaying the ad or brand; the second intermediation part(126) which is placed on the metal part, prevents the oxidation of the metal part, and intermediates the adhesion of the ink to the metal material; a print part(128) which is placed on the second intermediation part, and where the ad or brand is printed by using an ink; a coating part(130) which is placed on the print part and is friction-resistant to the ink of the print part; and an embossing part(132) which is placed on the coating part, protects all the members formed below the coating part, and reacts NaOH solution. Preferably the first intermediation part comprises 10-15 wt.% of acryl copolymer and the balance of a solvent; and the second intermediation part comprises 25-35 wt.% of polystyrene, 2-5 wt.% of acryl resin and the balance of a solvent.
