| titleOfInvention | Manufacturing method of surface-treated polyimide film |
| abstract | PROBLEM TO BE SOLVED: To detect defects such as coating unevenness and coating streaks on a film surface in the middle of production at an early stage, and to identify the cause of coating unevenness and take countermeasures using the result, coating unevenness The purpose of the present invention is to provide a method for producing a polyimide film having no defects by preventing the occurrence of coating stripes. SOLUTION: A method for producing a surface-treated polyimide film obtained by applying a coating liquid containing a surface treatment agent on at least one surface of a self-supporting film obtained from a polyimide precursor (a) solution and heating imidization, It is characterized by observing the thickness unevenness of the coated portion of the surface treatment agent of the coated and dried self-supporting film by a method selected from the schlieren method and the shadow graph method between the drying step of the coating solvent and the heating furnace. A method for producing a surface-treated polyimide film. [Selection figure] None |
