ABSTRACT:
A method for increasing the efficiency of electrostatic deposition of particulate matter on a surface, which comprises preparing a dispersion of electrostatically charged particles of an active material to be deposited on the surface, wherein the particles of active material have an average radius of r.sub.p1 and a total volume of V.sub.L1, in a space adjacent to the surface which contains a dispersion of particles of an inert material, electrostatically charged with the same polarity as said particles of active material, wherein the particles of inert material have an average radius of r.sub.p2 and a total volume of V.sub.L2, wherein r.sub.p1 >r.sub.p2 and ##STR1##
