Abstract:
The present embodiments disclose processes for preparing a polyester latex containing an amount of residual organic solvent which is less than 100 ppm by weight of the total weight of the polyester latex.
Abstract:
Disclosed is a polyester resin containing the polycondensation product of (a) at least one diacid, acid ester, or diester, and (b) at least two diols. The at least two diols include a disproportionated rosin diol and 2,2-bis(4-hydroxyphenyl)propane. Also disclosed is a toner composition having particles which include the disclosed polyester resin. Further disclosed is a method of preparing the disclosed polyester resin, and a method of forming toner particles that includes the disclosed polyester resin.
Abstract:
A method of forming a printed pattern on a substrate includes printing a pattern onto the substrate with a conductive ink including a conductive material, a thermoplastic binder and a solvent, curing the printed pattern, and fusing the printed pattern by feeding the printed pattern through a fusing system operated at a temperature of about 20° C. to about 130° C. above the glass transition temperature of the thermoplastic binder and at least 120° C. at a minimum, a pressure of from about 50 psi to about 1500 psi, and a feed rate through the fusing system of about 1 m/min to about 100 m/min. The method may be done continuously. The method improves the sheet resistivity of the printed ink.
Abstract:
Disclosed herein are formulations and processes for the preparation of pigment and wax dual dispersions by (1) providing a solution comprising a water and at least one surfactant in a dispersion apparatus comprising a container, a rotor-stator homogenizer, and a piston homogenizer coupled via a recirculation device; (2) adding at least one pigment to the solution; (3) forming a pigment dispersion by flowing the at least one pigment and the solution to the rotor-stator homogenizer via the recirculation device; (4) adding at least one wax to the pigment dispersion; and (5) flowing the at least one wax and pigment dispersion to the piston homogenizer via the recirculation device until a pigment and wax dual dispersion is formed. Also disclosed herein are pigment and wax dual dispersions, as well as a dispersion apparatus for preparing pigment and wax dual dispersions. In certain embodiments, a dispersion apparatus for preparing a pigment and wax dual dispersion may comprise a container, a rotor-stator homogenizer, a piston homogenizer, and a recirculation device coupled to the container and the homogenizers that allows a dispersion to flow between the container and the homogenizers.
