POLYAMIDE RESIN FINE PARTICLE DISPERSION LIQUID AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a polyamide resin (PAI) fine particle dispersion liquid which can be obtained by an industrially practicable and simple operation and a method for producing the same.SOLUTION: There are provided: a polyamide resin fine particle dispersion liquid which is obtained by mechanically dispersing polyamide resin fine particles having an average primary particle diameter of 100 nm to 300 nm with a dispersion medium with an ultrasonic wave device or the like in the presence of an anionic surfactant, a cationic surfactant, a nonionic surfactant or a high molecular weight surfactant; and a method for producing a polyamide resin fine particle dispersion liquid.
