Abstract: A polyimide precursor solution contains a polyimide precursor, particles, and a water-based solvent that contains an amine compound (A), an organic solvent (B) other than the amine compound (A) and amide compounds, and water, in which a boiling point of the organic solvent (B) is higher than a boiling point of the amine compound (A), and is 200° C. or higher and 300° C. or lower.

Abstract: A polyimide precursor solution includes a polyimide precursor that is a polymer of an aromatic tetracarboxylic dianhydride and an aromatic diamine compound, resin particles, an aqueous solvent containing water, and an amine compound having a boiling point of equal to or higher than 250° C. and equal to or lower than 300° C., in which a ratio of a volume of the resin particles to a volume of the amine compound (volume of resin particles/volume of amine compound) is equal to or more than 0.22 and equal to or less than 0.61.

Abstract: A powder coating material for fluidized-bed coating has a volume average particle diameter D50v of 5 μm or more and 20 μm or less. The powder coating material shows an aerated flowability energy AE of 5 mJ or higher and lower than 100 mJ as measured with a powder rheometer using a vessel having a cross-sectional area with Ø50 mm under conditions of a rotary blade tip speed of 100 mm/sec, a rotary blade helix angle of −5°, and an air flow rate of 20 ml/min.

Abstract: A fluidized-bed coating method includes: immersing at least part of a workpiece in a powder coating material contained in a fluidized-bed vessel while air is introduced from a bottom of the fluidized-bed vessel at an average air flow rate of 5 mm/min or higher and 20 mm/min or lower per unit area of the bottom so that a floating ratio of the powder coating material is 5% or higher and 20% or lower, the workpiece having a temperature higher than or equal to a softening temperature of the powder coating material and lower than or equal to a melting temperature of the powder coating material; taking the workpiece out of the powder coating material; and heating the powder coating material attached to the workpiece.
