    Abstract: A metallic nanoparticle dispersion comprising metallic nanoparticles characterized in that the dispersion comprises less than 50 μmol/g metal of an inorganic acid or a compound capable of generating such an acid during curing of a metallic layer or pattern formed from the dispersion. The presence of such small amounts an inorganic acid increases the conductivity of metallic layers or patterns formed from the metallic nanoparticle dispersions at moderate curing conditions.

    Abstract: A method of preparing a conductive metallic layer or pattern comprising the steps of: - applying a metallic nanoparticle dispersion on a support to obtain a metallic layer or pattern, - contacting the metallic layer or pattern with a solution containing an acid or an acid precursor capable of releasing the acid during curing of the metallic layer or pattern. It has been observed that by contacting the metallic layer or pattern with a solution containing an acid or an acid precursor capable of releasing the acid, higher conductivities at moderate curing conditions are obtained.
