PROBLEM TO BE SOLVED: To provide a laminate film manufacturing method, in which the characteristics of a base material film or the characteristics of a resin coating layer are further improved to dry efficiently, when a laminate film is manufactured by coating and drying a resin coating liquid containing liquid media of two kinds of different boiling points, wherein a phase difference development of the resin coating layer is enhanced in the laminate film having the resin coating layer laminated over the base material film.SOLUTION: A laminate film manufacturing method is characterized in that: a coating liquid containing a resin, a vaporizable medium A and a high-boiling point medium B having a higher boiling point than that of said vaporizable medium A is applied to one face or two faces of a base material film; and the applied film obtained is dried within a temperature range lower than the boiling point of said vaporizable medium A.SELECTED DRAWING: None |
