A pressure-sensitive adhesive layer formed on a substrate (for example, plastic) has excellent wettability to the surface of an adherend (preferably glass), and adheres to the adherend in a high temperature state and / or a high humidity state. Provided is a pressure-sensitive adhesive in which removability is sufficiently maintained over time and the compatibility of each component is excellent. A urethane pressure-sensitive adhesive containing urethane polyol, polyisocyanate, a plasticizer and a stabilizer, wherein the urethane polyol is a polymer of polyethylene glycol and polypropylene glycol and an isocyanate monomer, and the plasticizer is castor. It is a urethane pressure-sensitive adhesive containing an oil-based compound. An adhesive film coated with this adhesive is also provided. [Selection figure] None |
