The disclosure provides sustainable toner particles of from about 180 nm to about 250 nm in a sustainable toner composition having a hot offset temperature of from about 190&#xb0; C. to about 220&#xb0; C.

Optimized latex particle size for improved hot offset temperature for sustainable toners

The disclosure describes a one reaction process for making a bio-based polyester resin. The resultant polyester resin retains thermal properties as compared to a similar resin but made using previous multi-step processes conducted in separate vessels.

Simplified process for sustainable toner resin

The disclosure describes a process for making a polyester resin of defined acid value using a temperature-sensitive reaction and dipropylene glycol as a reagent.

Sustainable polyester resin of defined acid value

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.

Steam injection process for preparing polyester latex and apparatus thereof

A phase inversion emulsification process includes dissolving a polyester resin in a mixture comprising (1) an organic solvent, (2) a first portion of a total amount of neutralizing agent, and (3) a first portion of water, neutralizing the dissolved polyester resin with a second portion of neutralizing agent, the second portion of neutralizing agent including the remaining amount of the total amount neutralizing agent, forming an emulsion by adding a second portion of water after the neutralizing step, and removing a portion of the organic solvent from the emulsion to provide a latex.

Process for preparing polyester emulsions

A method for preparing toner particles is disclosed. In embodiments, a suitable method includes aggregating a mixture comprising at least one resin, an optional pigment and an optional wax to form aggregated particles, freezing aggregation of particles by adjusting the pH of the aggregated particles to a freezing aggregation pH; coalescing the aggregated particles to form toner particles at a first pH that is higher than the freezing aggregation pH; and recovering the toner particles.

Toner processes

A process and system for making a resin emulsion suitable for use in forming toner particles including a silicone free anti-foam agent to control foam during formation of a polyester dispersion.

Efficient solvent-based phase inversion emulsification process with defoamer
