PURPOSE: To provide a protective film with proterties in retaining a quenching state even if a mold releasing film adheres, being made an inspection of inclusion of a foreign matter or the like to be simply, little deterioration of adhesion to an adhesive, in an inspection of a polarizing plate, a phase contrast polarizing plate, or a phase contrast plate involved optical evaluation between two polarizing plates in a crossed nicols state. CONSTITUTION: A protective film for an adhesive bond is a mold releasing film in order to protect an adhesive surface coated on a polarizing plate and a phase contrast plate of a liquid crystal display and the protective film comprises a laminated film provided with a mold releasing layer on a side surface of an in-plane refractive index isotropy biaxial orientation polyester film, the laminated film having residue adhesive index of at least 80%. The mold releasing layer preferably comprises a cured silicone resin as a principal component.
