摘要:
Copolymer encapsulated wax particles and their use in forming toner compositions having particles with a desired circularity and size are provided.
摘要:
A process for making toner particles is provided. In embodiments, a suitable process includes melt mixing a resin in the absence of an organic solvent, optionally adding a surfactant to the resin, adding to the resin at least one colorant and other optional toner additives, adding to the resin a basic agent and water to form a mixture, and subjecting the mixture to acoustic mixing at a suitable frequency to form to form an emulsion. A phase inversion may then be performed to create a phase inversed emulsion including a disperse phase comprising molten resin and the optional ingredients of the toner composition, at which time toner-sized droplets may be solidified from the disperse phase into toner particles, which can be recovered for use.
摘要:
A process for making a resin emulsion suitable for use in forming toner particles is provided. In embodiments, a suitable process includes melt mixing a resin in the absence of an organic solvent, optionally adding a surfactant to the resin, adding to the resin a basic agent and water, and subjecting the resin, basic agent and water to acoustic mixing at a suitable frequency to form an emulsion of resin particles. In embodiments, the resin emulsion thus produced may be utilized to form a toner.
摘要:
A process comprising heating a latex and a colorant, and optionally a wax, and wherein the latex contains a polymer with a Mz value of from about 60,000 to about 150,000.
摘要:
A process for the preparation of a latex polymer by (i) preparing or providing a water aqueous phase containing an anionic surfactant in an optional amount of less than or equal to about 20 percent by weight of the total amount of anionic surfactant used in forming the latex polymer; (ii) preparing or providing a monomer emulsion in water which emulsion contains an anionic surfactant; (iii) adding about 50 percent or less of said monomer emulsion to said aqueous phase to thereby initiate seed polymerization and to form a seed polymer, said aqueous phase containing a free radical initiator; and (iv) adding the remaining percent of said monomer emulsion to the composition of (iii) and heating to complete an emulsion polymerization thus forming a latex polymer.
摘要:
The present disclosure provides processes for reducing the particle size of latex resins and toners produced with such resins. In embodiments, a gel latex may be formed as a seed particle and then utilized to form latex resins and toner particles. In accordance with the present disclosure, one may be able to utilize materials for the production of latex resins and toners which may otherwise produce particles that are too large in the absence of the gel latex.
