される分野に適用する試みもみられるに至っている。The curtain coating method is a method in which a free-falling curtain made of one or more coating liquids is formed, and the curtain is made to collide with the object to be coated to form a coating film on the object. However, due to the demand for improved coating quality, high-precision coating has gradually been required, and in recent years, the Sho-Ter 2μ/33 and Sho-Ter 3J4L4L7 publications have been used. Attempts have also been made to apply the curtain coating method as disclosed to fields where precision is particularly required, such as the production of photographic light-sensitive materials.
