A method for producing an electrically conductive thin film on a substrate is disclosed. Initially, a reducible metal compound and a reducing agent are dispersed in a liquid. The dispersion is then deposited on a substrate as a thin film. The thin film along with the substrate is subsequently exposed to a pulsed electromagnetic emission to chemically react with the reducible metal compound and the reducing agent such that the thin film becomes electrically conductive.

Method for reducing thin films on low temperature substrates

The present invention relates to a method of preparing a polymer modified pigment comprising the steps of, combining, in any order, a modified pigment comprising a pigment having attached at least one reactive group, a polymer comprising at least one functional group, and a non-reactive diluent, to form a reaction mixture, reacting the polymer and the modified pigment in the reaction mixture to form a mixture comprising the polymer modified pigment and the non-reactive diluent; and removing the non-reactive diluent from the mixture to form the polymer modified pigment. Also disclosed are the resulting polymer modified pigments and inkjet ink compositions comprising them.

Method of preparing polymer modified pigments

A method of forming a modified pigment comprising a pigment having attached at least one polymeric group is described. In one embodiment, a polymer, a pigment, a linking agent, and an optional activating agent are combined, and the linking agent is reacted with the polymer and the pigment to form the modified pigment. In another embodiment, a polymer melt is formed comprising a polymer and an optional plasticizer, and the polymer melt, a pigment, and an optional activating agent are combined, in any order, under high-intensity mixing conditions. Also disclosed are modified pigments having specific properties and inkjet ink compositions comprising them.
