The present invention relates to a process which comprises: providing a substrate having a surface; applying a dispersion to the surface, wherein the dispersion comprises at least one liquid dispersant, and electrostatically stabilized silver nanoparticles having a zeta potential of from &#x2212;20 to &#x2212;55 mV in the dispersant at a pH value of from 2 to 10; and heating one or both of the surface and the dispersion applied thereon to a temperature of from 50&#xb0; C. below the boiling point of the dispersant to 150&#xb0; C. above the boiling point of the dispersant, to form a conductive coating on the surface.

Production of conductive surface coatings using a dispersion containing electrostatically stabilised silver nanoparticles

Printable compositions comprising: (a) 5 to 40 parts by weight of silver nanoparticles having a maximum effective diameter of 150 nm, as determined by laser correlation spectroscopy; (b) 50 to 99.5 parts by weight of water; (c) 0.01 to 15 parts by weight of a dispersing agent; (d) 0.5 to 5 parts by weight of a film former; and (g) 30 to 70 parts by weight of metal particles having a maximum effective diameter of 10 &#x3bc;m, as determined by laser correlation spectroscopy; wherein the printable composition has a viscosity of at least 1 Pa&#xb7;s; processes for producing electrically conductive coatings using such compositions and electrically conductive coatings prepared thereby.

Printable compositions containing silver nanoparticles, processes for producing electrically conductive coatings using the same, and coatings prepared thereby

The present invention relates to a substrate with at least one section having a surface decoration and a coating between the surface and the decoration. The coating can be peeled from the surface, and is prepared from an aqueous anionic polyurethane-polyurea dispersion which are free from co-solvents.
