A method of electroless plating atleast one homogeneous metalcoating in a predetermined pattern on a substrate surface havingpendant hydroxy groups comprising reacting the pendant hydroxygroups of the substrate surfacewith a silyl hydride to form a silicon hydride bond directly on thesubstrate surface without any intervening bonds; immersing thesubstrate surface in a metal ionsolution to provide a monatomicmetal layer in a predeterminedpattern on the substrate surface;and immersing the activated substrate surface in a solution containing a chemical reducing agentand metal ions to build up at least
one homogeneous metal coatingdirectly only on the monatomicmetal layer.
