Abstract:
1. An electrostatic spray device comprising: a storage reservoir for storing a composition; a spray electrode to which the composition is supplied from the storage reservoir; and a discharge electrode provided in the vicinity of the spray electrode, the composition being electrostatically sprayed from the spray electrode by application of a voltage across the spray electrode and the discharge electrode, the composition comprising at least one of ester compounds represented by the following formulas (1) through (5), respectively: wherein the composition has (i) an electric resistance of not less than 1×10 the composition further containing a dispersion medium for dispersing the at least one of ester compounds, and having a vapor pressure of less than 14 Pa at a temperature of 20° C.; the dispersion medium containing (i) a low-vapor pressure component containing dipropylene glycol-n-propyl ether, (ii) a resistivity adjustment component, and (iii) a surface tension adjustment component.
