ABSTRACT:
A method of depositing a metal on a dielectric surface is disclosed. The method comprises treating the surface with a stable hydrosol obtained by mixing and heating together in an acidic aqueous medium (1) a salt of a noble metal with (2) an organic compound containing at least two oxygen atoms selected from (a) an organic carbonate having a structural formula of ##STR1## where R = H, an alkyl radical, (b) ethylene glycol and (c) 1,3 dioxane. The treated surface is then exposed to a suitable electroless metal deposition solution to catalytically deposit an electroless metal deposit thereon.
