A process for preparing an aqueous dispersion of pigment particles is described. The pigment particle contains a pigment and an aminoplast resin which surrounds or embeds the pigment. The process includes (i) a step of subjecting an aqueous suspension of a pigment in the form of coarse particles to milling so that the coarse particles are comminuted in the presence of a polymeric dispersant to a particle diameter d(v 0.9) of below 1500 nm, as determined by laser diffraction; and (ii) a step of polycondensation of an aminoplast pre-condensate in the aqueous suspension of the comminuted particles of the pigment obtained in step (i) or during the milling of step (i). The polycondensation is performed in the presence of an acid catalyst at pH of below 5.5. The aqueous dispersion obtained by the process and the use of the aqueous dispersion for tinting waterborne liquid coating composition are also described.

The present disclosure discloses a liquid electrophotographic ink. The ink can include (A) a liquid vehicle; (B) at least one colorant; (C) a resin comprising an ethylene acid copolymer; (D) an ethylene/(meth)acrylic acid C1-10 alkyl ester copolymer selected from the group consisting of an ethylene/methyl acrylate copolymer and an ethylene/butyl acrylate copolymer; and (E) a condensation product of urea and aldehyde.

A conductive paste is provided for forming conductive traces on substrates. The conductive paste includes a vehicle and conductive material. The vehicle includes a resin, a plasticizer, and a solvent in which the resin is dissolved. After application to a substrate, the conductive paste is cured at ambient temperature by evaporation of the solvent from the paste, to thereby form a conductive trace on the substrate. The conductive trace does not require a curing agent, and attains low resistivity within minutes of application to the substrate.
