A process for printing a metal wire pattern on a substrate, including: printing a first salt solution including a metal ion that will undergo a reduction half-reaction; printing a second salt solution containing a reductant that will undergo an oxidation half-reaction in contact with the first salt solution, resulting in the reduction of the metal ions of the first salt solution; and allowing the first and second salt solutions to react by a galvanic reaction, causing reduced metal ions of the first salt solution to precipitate as a solid, on the substrate.

A low melt or ultra low melt toner includes at least one amorphous polyester of an alkoxylated bisphenol based polyester, a crystalline polyester derived from the reaction of an aliphatic dicarboxylic acid or aromatic dicarboxylic acid with an aliphatic diol, at least one colorant and at least one fluorescence agent. Methods of authentication of the toner, of authentication of documents formed from the toner, of embedding information in documents, and the like are also set forth.

Low melt color toners with fluorescence agents

The present disclosure provides toners and processes for making said toners. In embodiments, the toners are invisible when viewed under natural light, but possess a fluorescent agent that renders them visible when exposed to UV light of a specific wavelength. In other embodiments the toners have a color under natural light, and a different color when exposed to UV light.
