Summary: | To provide a method for manufacturing a film that can apply a coating liquid containing fine particles to a substrate evenly.SOLUTION: A method for manufacturing a film F includes: an application step of applying a coating liquid to a substrate S using a bar 11; and a drying step of drying the coating liquid applied to the substrate S. The coating liquid contains a resin component, fine particles and a dispersion medium of dispersing the resin component and the fine particles. The bar 11 has surface free energy that is higher than surface tension of the coating liquid.SELECTED DRAWING: Figure 3
【課題】微粒子を含有する塗工液を基材に均一に塗布できるフィルムの製造方法を提供する。【解決手段】フィルムFの製造方法は、バー11を用いて基材Sに塗工液を塗布する塗布工程と、基材Sに塗布された塗工液を乾燥させる乾燥工程とを含む。塗工液は、樹脂成分と、微粒子と、樹脂成分および微粒子を分散させる分散媒とを含有する。バー11の表面自由エネルギーは、塗工液の表面張力よりも高い。【選択図】図3 |
