Disclosed is a urethane adhesive comprising a urethane polyol, a polyisocyanate, a plasticizer, and a stabilizing agent, wherein the urethane polyol is a polymer of a polyethylene glycol and a polypropylene glycol with an isocyanate monomer, and the plasticizer comprises a castor oil-based compound. With regard to the adhesive, an adhesive layer formed on a substrate (for example, a plastic) is excellent in wettability to a surface of an adherend (preferably glass) and releasability is sufficiently maintained even when exposed to a condition of a high temperature and/or a high humidity for a long time, and also each component is excellent in compatibility. An adhesive film coated with the urethane adhesive is also provided. |
