Abstract
Polymer particles excellent in uniform dispersibility and the use thereof are provided. The polymer particles contain a surfactant, and have a coefficient of variation in the volume-based particle diameter distribution in the range from not less than 13.0% to not more than 25.0%. When 15.0 g of water is added to 5.0 g of the polymer particles so as to disperse the polymer particles in the water by performing a dispersion treatment for 60 minutes using an ultrasonic cleaner, and furthermore when an obtained dispersion liquid is put into a centrifuge tube with an inside diameter of 24 mm so as to be centrifuged, by a centrifugal separator, under conditions that K factor is 6943 and a rotating time is 30 minutes to recover a supernatant, a concentration of non-volatile components in the obtained supernatant is less than 3.5 wt. %.
