Method of producing film by inkjet process, and film

摘要

To provide a method of producing a film, comprising: ejecting a liquid B over a liquid surface of an active energy ray-curable liquid as a liquid A by an inkjet process, according to a predetermined periodic signal; and subsequently applying an active energy ray to the liquid A and the liquid B so as to perform curing and obtain a film which comprises a pattern according to any one of (1) to (4) below, (1) a smooth pattern having a periodic amplitude based upon a trigonometric function, (2) a pattern having a periodic depression, (3) a pattern in the form of a periodic flat surface, and (4) a pattern having a periodic semicylindrical shape.

1. A method of producing a film, the method comprising:
(I) ejecting a liquid B over a liquid surface comprising an active energy ray-curable liquid A by an inkjet process, according to a predetermined periodic signal; and subsequently (II) applying an active energy ray to the liquid A and the liquid B, thereby curing and obtaining a film comprising a pattern according to any one of (1) to (4):
(1) a smooth pattern comprising a periodic amplitude based upon a trigonometric function;(2) a pattern comprising a periodic depression;(3) a pattern in the form of a periodic flat surface; and(4) a pattern comprising a periodic semicylindrical shape, wherein the liquid A is greater than the liquid B in static surface tension at 25° C., and the liquid A has a static surface tension of 35 mN/m or greater at 25° C.
