Abstract
A method to produce a coated film comprising the steps of: (a) ejecting a coating liquid continuously from an ejecting portion of an extrusion head; (b) applying the coating liquid ejected from the ejecting portion of the extrusion head onto a continuously conveyed film; and (c) stopping the ejection of the coating liquid, wherein an organic solvent is supplied to a vicinity of the ejecting portion of the extrusion head from before starting the ejection of the coating liquid to after starting the ejection of the coating liquid in step (a).

- (a) ejecting a coating liquid continuously from an ejecting portion of an extrusion head;
- (b) applying the coating liquid ejected from the ejecting portion of the extrusion head onto a continuously conveyed film;
- and
- (c) stopping the ejection of the coating liquid, wherein
- an organic solvent is supplied to a vicinity of the ejecting portion of the extrusion head from before stopping the ejection of the coating liquid to after stopping the ejection of the coating liquid in step (c).
A method to produce a coated film comprising the sequential steps of:
- (a) ejecting a coating liquid continuously from an ejecting portion of an extrusion head;
- (b) applying the coating liquid ejected from the ejecting portion of the extrusion head onto a continuously conveyed film;
- (c) stopping the ejection of the coating liquid;
- and
- (d) moving the extrusion head away from the continuously conveyed film while the coating liquid is continuously ejected from the ejecting portion of the extrusion head,
- wherein
- an organic solvent is supplied to a vicinity of the ejecting portion of the extrusion head from before step (b) to after step (d).
