Abstract
Official abstract text for this publication.
A method for preparing a latex or dispersion, the method comprising contacting at least one resin with an organic solvent to form a resin mixture; neutralizing the resin mixture with a neutralizing agent; and subjecting the resin mixture flow to steam flow in a continuous manner to form a dispersion. A method for forming toner, the method comprising: contacting a resin to an organic solvent and a neutralizing agent to form a resin mixture; subjecting the resin mixture flow to a steam flow in a continuous manner to form a dispersion; aggregating particles from a pre-toner mixture, the pre-toner mixture comprising the dispersion, an optional colorant, and an optional wax; and coalescing the aggregated particles to form toner particles. An apparatus that can perform the methods.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for preparing a latex or dispersion, the method comprising: contacting at least one resin with an organic solvent to form a resin mixture; neutralizing the resin mixture with a basic neutralizing agent; subjecting the resin mixture to steam flow in a continuous manner to form a dispersion by continually pumping the resin mixture and the steam flow into a mixing zone thereby forming a latex where the resin mixture and steam flow contact within th…
