Abstract (en)

The method comprises sequentially introducing two particle fractions, each of which has different sizes and/or compositions, on a flat substrate using electrostatic field with different potential differences. The electrostatic field has a potential difference of 30-100 kV. A distance of the electrodes developing the electrostatic field is 15-300 mm. The particles have an average particle size of 20-70 mu m. The substrate has an adhesion promoting layer that is conductive and is a resin layer or a lacquer layer. The average applied quantity of the particles is 20-30 g/m 2>.
