A method of preparing a conductive pattern on a substrate includes the steps of applying a receiving layer on a substrate, applying a metallic nanoparticle dispersion on the white receiving layer thereby forming a metallic pattern, and sintering the metallic pattern, characterized in that the receiving layer has a roughness Rz between 1 and 75.

Method of manufacturing a conductive pattern

A UV curable colourless inkjet liquid includes at least one radical photoinitiator and a polymerizable composition, wherein the polymerizable composition contains a mixture of: a) 25 to 50 wt % of a monofunctional methacrylate; b) 40 to 70 wt % of a polyfunctional acrylate; and c) 0 to 15 wt % of a monofunctional acrylate; with the weight percentage wt % based on the total weight of the polymerizable composition.

An inkjet printing method includes the steps of: a) printing a first print job by jetting a free radical UV curable white inkjet ink from a white ink print head and one or more free radical UV curable color inkjet inks from one or more other print heads in a UV curable inkjet printer; b) filling the white ink print head in the UV curable inkjet printer with a safeguard liquid including one or more free radical polymerizable monomers; c) printing a second print job employing only the one or more other print heads in the UV curable inkjet printer for jetting one or more free radical UV curable color inkjet inks; d) replacing the safeguard liquid of the white ink print head in the UV curable inkjet printer by UV curable white inkjet ink; and e) printing a third print job by jetting free radical UV curable white inkjet ink from the white ink print head and jetting one or more free radical UV curable color inkjet inks from one or more other print heads in the UV curable inkjet printer.

An inkjet printing method for producing images durable for outdoor usage includes the steps of: a) inkjet printing on a substrate a UV curable colorless primer including monofunctional monomers in a range of 40 wt % to 65 wt % based on the total weight of the UV curable colorless primer; b) at least partially UV curing the inkjet printed UV curable colorless primer; and c) inkjet printing on the at least partially cured UV curable colorless primer one or more UV curable color inkjet inks including monofunctional monomers in a range of 30 wt % to 60 wt % based on the total weight of the UV curable color inkjet inks; wherein a ratio of the wt % monofunctional monomers in the UV curable colorless primer over the wt % monofunctional monomers in the one or more UV curable color inkjet inks is between 0.65 and 2.10.
