The present invention is a retention label that does not contain toluene, wherein the retention label includes an adhesive layer having a release layer formed on an upper surface thereof so as to be adhered to the container by an interview; A base layer formed on the lower surface of the adhesive layer and comprising pulp; A metal layer formed on a lower surface of the base layer; A printing layer formed on a lower surface of the metal layer and printed using an ink composition containing an alcohol-based solvent; It is formed on the lower surface of the printing layer and includes a protective coating layer that protects the surface of the retention label and prevents elution into an aqueous sodium hydroxide solution; The protective coating layer contains 10 to 40% by weight of a polyvinyl butyral resin, 1 to 20% by weight of a ketone resin, 0.01 to 1% by weight of an antistatic agent, 0.01 to 1% by weight of polyethylene wax, and 40 to 80% by weight of an alcohol-based solvent. Including coating compositions; The present invention relates to a retention label that does not contain toluene, which is environmentally friendly because it does not use toluene, which is highly carcinogenic and harmful as a solvent, and does not contain toluene, which can minimize the occurrence of contaminants in the process of removing the label. |
