摘要:
Environmentally friendly toner particles are provided which may include a bio-based amorphous polyester resin, optionally in combination with another amorphous resin and/or a crystalline resin. Methods for providing these toners are also provided. In embodiments, the bio-based amorphous polyester resin includes a biologically derived diol, such as 2,3-butanediol.
摘要:
A process for making a latex emulsion suitable for use in a toner composition includes contacting at least one crystalline polyester resin with an organic solvent and a stabilizing agent to form a resin mixture, adding a neutralizing agent, and deionized water to the resin mixture, removing the solvent from the formed latex, and continuously recovering latex particles.
摘要:
Embodiments include a toner having a polyester resin derived from diacids and diesters, in combination with at least one diol, in embodiments a cycloaliphatic diol, an optional crystalline resin, an optional colorant, and an optional wax.
摘要:
A process for making silica-containing latex particles involves polymerizing monomer in an emulsion comprising the monomer, water, silica particles, and optionally at least one surfactant, by adding at least one free radical initiator to the emulsion to form the silica-containing latex particles. In a preferred method, semicontinuous polymerization employing a seed latex is used to form the latex resin. The process achieves a silica-containing latex in which the silica is chemically incorporated therein that is ideally suited for use in the manufacture of toner and developer for xerographic use.
摘要:
The present disclosure provides a bio-based, branched polyester resin comprising the condensation product of a hydroxyl donor, including glycerol carbonate, and a cyclic polyhydroxyl acceptor, such as abietic acid, neoabietic acid, palustric acid, levopimaric acid, dihydroabietic acid, pimaric acid, and isopimaric acid, that may be used with a polyacid, including fumaric acid, maleic acid, succinic acid, itaconic acid, dodecylsuccinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, azelaic acid, and dodecane diacid, to form a polyester useful in manufacturing toner for imaging devices.
