A metallic nanoparticle dispersion includes a dispersion medium characterized in that the dispersion medium includes a solvent according to Formula I, 

Metallic nanoparticle dispersion

A radiation curable fluid includes a vinylether (meth)acrylate monomer, a compound including a sulfonic acid group, and a polymeric dispersant including heterocyclic groups having hetero atoms consisting of one or two nitrogen atoms.

Radiation curable fluids

The present invention relates to a dispersion comprising metallic, metal oxide or metal precursor nanoparticles and a polymeric dispersant, the dispersant comprising an anchor group with affinity for the metallic, metal oxide or metal precursor nanoparticles that is chemically bonded to a polymeric backbone characterized in that the dispersant has a 95 wt. % decomposition at a temperature below 300&#xb0; C. as measured by Thermal Gravimetric Analysis. It further relates to metallic fluids or inks prepared from the dispersion and to the preparation of the dispersion and the metallic fluid or inks.

Dispersion comprising metallic, metal oxide or metal precursor nanoparticles

A dispersion includes metallic, metal oxide, or metal precursor nanoparticles; a thermally cleavable polymeric dispersant; an optional dispersion medium; and a thermally cleavable agent. Pastes, coated layers, and patterns may contain the dispersion. A method for producing the specific thermally cleavable dispersant and for producing the metallic nanoparticle dispersions. The dispersions allow the reduction or avoidance of organic residue in coated layers and patterns on substrates, the use substrates of low thermal resistance, and faster processing times.
