Thin film formation method

Abstract

Abstract PURPOSE:To form uniformly a thin film consisting of a high polymer material by transferring the coating liquid developed preliminarily on the surface of a roller to a base plate then rotating the base plate around the shaft roughly perpendicular to said coating surface to smooth and thin the coated film then drying the film. CONSTITUTION:A coating liquid consisting of a high polymer soln. developed preliminarily on the surface of a roller is transferred to a base plate then the base plate is rotated around the shaft roughly perpendicular to the surface coated with the coating liquid to smooth and thin the coated film and is dried, by which a thin film consisting of the high polymer material is formed. Since the roller coating is utilized as a method for supplying the coating liquid for the purpose of spinning coating to form the uniform film, there is no excess supply of the coating liquid and the contamination of the side and rear surfaces of the base plate and further the surrounding equipment, etc., and the labor for washing the same, etc. is not required. The above-mentioned method is used for forming a photosensitive resin film, etc. for consituting a color separating stripe filter for, for example, a single tube type color television camera.
