Abstract
A process for producing a seamless capsule wherein a two-layer droplet is ejected from a double orifice type nozzle in an aqueous hardening liquid, and an outer layer of the droplet is hardened under cooling, the viscosity of the aqueous hardening liquid being made within the range of 20 to 100 mPa.multidot.s, and any difference in specific gravity between any two of the liquids of the layers ejected from the nozzle and the aqueous hardening liquid is made within 0.05.
