摘要

PROBLEM TO BE SOLVED: To provide a method for producing a resin particle-dispersed polyimide precursor solution in which the dispersibility of resin particles is improved. SOLUTION: Polyester resin particles, urethane resin particles, vinyl resin particles, (meth)acrylic resin particles, (meth)acrylic acid ester resin particles, styrene/(meth)acrylic resin particles, polystyrene resin particles, and polyethylene in an aqueous solvent. In a resin particle dispersion liquid in which at least one resin particle selected from the group consisting of resin particles is dispersed, in the presence of an organic amine compound, a tetracarboxylic dianhydride and a diamine compound are polymerized to form a polyimide precursor. A method for producing a resin particle-dispersed polyimide precursor solution for forming a body. [Selection diagram] None
