Kind Code:
A1
Abstract:
[Problem] To provide a resin composition having excellent dispersibility and low impurity content. [Solution] This resin composition has, as a main component, an aromatic polyamide and/or aromatic polyamic acid, wherein when rA (nm) represents an average hydrodynamic radius as measured through dynamic light scattering using an aqueous dispersion containing the powder in an amount of 100 mass ppm, and rB (nm) represents an average hydrodynamic radius after ultrasonic treatment of the dispersion, rA/rB is greater than 1 and rB is 100 nm to 10,000 nm.
