    摘要: A process for preparing resinous particles for a coating composition, which comprises the steps of (1) subjecting an aqueous resin composition having an ionic group and no material solubility or dispersibility in water is dissolved or dispersed in an aqueous medium by at least partly neutralizing the ionic group to treatment with a powdering agent while applying thereto an operation for pulverization to deposit the resin in a particulate form and (2) recovering the deposited resinous particles from the aqueous medium.
