| titleOfInvention | Method for producing polyimide electrodeposition paint |
| abstract | [Problem] To provide a method for producing a suspension type polyimide electrodeposition coating which is difficult to change even after long-term storage and can form an electrodeposition film having high uniformity of film properties at a high electrodeposition rate even after long-term storage. A block copolymer polyimide having a siloxane bond in a molecular skeleton and an anionic group in a molecule is dissolved in a water-soluble polar solvent, and the concentration of the block copolymer polyimide is 15 to 25% by weight. A step of blending a polyimide solvent with a poor solvent and a basic compound for the block copolymerized polyimide, and allowing the solution to stand at room temperature until the amount of change in electrical conductivity per day becomes 0.1 mS / m or less, A first dilution step in which an amount of water smaller than the amount of the block copolymerized polyimide that can be deposited in the polyimide solution after being left standing is added under stirring, and water is further added under stirring after the first dilution step. And a second dilution step for depositing the block copolymerized polyimide. [Selection figure] None |
