TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Process: The process takes place in a liquid or a liquid mixture containing at least an ionic liquid, optionally one or more organic liquids and/or optionally one or more additives. In the process, the metal ion is dissolved in the liquid or liquid mixture. The two or more metal layers are deposited by: repeated electrochemical metal deposition of one or more metals and/or the simultaneous use of different metal salts. Preferred Components: The surface of the particle substrate contains at least a metal, metal alloy, semi-metal, doped inorganic material, conductive or metalized ceramic, or conductive and/or metalized plastics. The particle substrate is a geometrically anisotropic particle, preferably plate or needle like particle. The particle substrate contains a composite layer. The particle size of the particle substrate is 0.5-800, preferably 1-200 mu m. The electrochemical metal is gold, silver, palladium, platinum, copper, titanium, tantalum, zirconium, zinc, vanadium, tin, iron, germanium, silicon or aluminum.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The ionic liquid exhibits at least a tetraalkylammonium-, tetraalkylphosphonium-cation, where the alkyl group has 1-10C atom, or a heterocyclic cation, preferably imidazolium cation of formula (A), pyrrolidinium cation of formula (B), pyridinium cation of formula (C) or morpholinium cation of formula (D). The cation is at least a tetraalkylammonium-, tetraalkylphosphonium-, 1,1-dialkylpyrrolidinium-, 1-hydroxyalkyl-1-alkyl-pyrrolidinium-, 1-hydroxyalkyl-3-alkyl-imidazolium or 1,3-bis(hydroxyalkyl)imidazolium cation, where the alkyl or alkylene chain of the hydroxyalkyl group contain 1-10 carbon atoms. The anion is hexafluorophosphate, boron tetrafluoride, alkyl sulfate, perfluoroalkyl sulfonate, perfluoroacetate, bis(fluorosulfonyl)imide, bis(perfluoroalkylsulfonyl)imide, tris(perfluoroalkyl)trifluorophosphate, bis(perfluoroalkyl)tetrafluorophosphate, tri(perfluoroalkylsulfonyl)methide or perfluoroalkylborate.Either R1a-R4a = H, -CN, -OR1a, -NR1a2, -P(O)R1a2, -P(O)(NR1a2)2, -C(O)R1a, 1-20C-alkyl, 2-20C-alkenyl with one or more double bonds, 2-20C-alkynyl with one or more triple bonds, saturated, partially or completely unsaturated 3-7C-cycloalkyl (optionally substituted by 1-6C-alkyl), or saturated, partially or completely unsaturated heteroaryl, heteroaryl-1-6C-alkyl or aryl-1-6C-alkyl, where the substituents R1a-R4a is optionally, partially or completely substituted by halo, preferably F and/or Cl, OR2b, CN, C(O)OH, C(O)NR2b2, SO2NR2b2, C(O)X, SO2OH, SO2X or NO2, the non-adjacent R1a and R4a are optionally, completely substituted by halo, and one or two non-adjacent and non-heteroatom bonded carbon atom of R1a-R4a is optionally substituted by O, S, S(O), SO2, C(O), N+R2b2, C(O)NR2b, SO2NR2b, P(O)(NR2b2)NR2b, PR2b2=N, or P(O)R2b; orR1a+R2a+R3a+R4a = a ring system;R2b = H, no, partially or perfulorinated 1-6C-alkyl, 3-7C-cylcoalkyl, optionally substituted phenyl; andX = halo. EXAMPLE - Silvertrifluoromethylsulfonate (0.4 mol/l) was dissolved in 1-ethyl-3-ethylimidazoliumtrifluoromethylsulfate (80 ml). The obtained mixture was galvanostatically deposited on to be coated plate like Minatec 31 (RTM: Conductive pigment) using silver as anode and platinum as cathode to obtain silver particle, where the amount of the silver is approximately 45%.
