摘要： Cold pressure fix toner compositions include at least one crystalline polyester having a melting point in a range from about 30° C. to about 130° C., a rosin acid-based polyester resin and an amorphous polyester having a Tg higher than the rosin acid-based polyester. The crystalline polyester can have a melting point in a range from about 30° C. to about 130° C., the rosin acid-based polyester resin can have a Tg in a range from about 0° C. to about −45° C. and an amorphous polyester having a Tg in a range from about 40° C. to about 70° C. The temperature difference between the rosin acid-based polyester resin and the amorphous polyester resin can be in a range from about 30° C. to about 110° C.

摘要： A method for forming a dispersion includes mixing graphene particles, a fluorosilane coupling agent and a first solvent to produce a first dispersion wherein the graphene particles are from about 0.1 to about 0.8 weight percent of the first dispersion. The method includes concentrating the first dispersion by removing the first solvent to produce a second dispersion wherein the graphene particles are from about 2.0 to about 10.0 weight percent of the concentrated dispersion. The concentrated dispersion is mixed with a fluoropolymer dispersion including a second solvent, a surfactant, and fluoropolymer particles wherein the fluoropolymer dispersion has a solids content of about 30 weight percent to about 50 weight percent to form a second dispersion. A polymer binder in a third solvent is mixed with the second dispersion to form the coating dispersion.

摘要： A silver paste ink composition comprises a plurality of first particles comprising silver; a polymer binder; a carrier solvent; and a plurality of second particles comprising silver. The second particles are nanoparticles that are different than the first silver particles, the amount of second particles in the ink composition being sufficient to impart a first color to the uncured ink composition, the first color being different than the color of the same ink composition without the nanoparticles. The silver nanoparticles have a property of causing a change in the color of the ink composition when the ink composition is cured.
