Abstract
Disclosed are a label and a method of manufacturing the same, the label comprising: a first base film; a first ink layer formed on the exterior top part of the first base film, and comprising a metal or metal oxide that changes from its original color to another color by being oxidized by a laser; and a resin coating layer coated on the first ink layer to protect the first ink layer, wherein the laser passing through a part or the whole of the resin coating layer is transmitted to the first ink layer. According to the present invention, there is no oxidation residue; thus, the efficiency of marking is excellent and any possibility of change in quality due to aging can be eliminated. In addition, the color rendering is excellent, and the scratch resistance, chemical resistance and heat resistance are superior.
