Abstract: A solvent based ink formulation for inkjet printing, particularly on plastics and non-porous surfaces, including 1-40% by weight of a ketone solvent, 10-90% by weight of a mixture of cosolvents, 0.1-10% by weight of a (co)polymer binder, 0.1-10% by weight of dispersants/wetting agents, and 0.1-10% of plasticizers to give a formulation having flash point higher than 60.degree. C.
Abstract: Compositions for conductive inks are described which are based on conductive (co)polymers and conductive mineral fillers, as well as processes for printing conductive elements. The printed compositions can be then subjected to the action of light beams produced by a coherent light source in order to obtain printed portions having a desired conductivity level.
