Abstract
The present invention provides a laminated film including at least two layers of an outer layer having a printed portion on a surface and an inner layer subjected to an antifogging treatment in which principal resin comprising a solid content of the printed portion is made of chlorinated polypropylene-based resin or urethane-based resin. This antifog laminated film hardly degrades in an antifogging property even when the antifog laminated film subjected to printing on the outer layer of a surface subjected to the antifogging treatment and the printed surface are strongly brought into contact with each other due to an operation of winding the film into a roll or the like.
