A method of coating a first resin solution containing a polymerization inducer on a moving web-like support with a coating device, comprising conveying the support to pass near the coating device without coming in contact with the coating device, disposing the first resin solution in a form of a first resin solution layer from the coating device onto the support; the first resin solution layer having a lower surface which faces the support and an upper surface opposite to the lower surface; and the coating device having a first release point at which the upper surface leaves the coating device and a second release point at which the lower surface leaves the coating device; overlaying the first release point with a solvent, thereby superimposing a solvent layer on the upper surface of the first resin solution layer; overlaying the second release point with a second resin solution which does not contain a polymerization inducer, thereby superimposing a second resin solution layer on the lower surface of the first resin solution layer; and applying the superimposed layers onto the support so that the solvent layer forms an uppermost layer on the support.

Method of forming layers on a support

A coating apparatus is disclosed. The apparatus comprises a coating head having a slide face along which a coating liquid flows down and a roll moving a continuous web downwardly. The slide face and the roll define a space for forming a sustained liquid mass therein. The coating head has a bottom face which is provided with a groove in the proximity of and substantially parallelly to the slide face whereby a thin liquid film is formed on the web at high speed.
