摘要:
The present disclosure provides processes for producing toners. In embodiments, alkyl or alkyl ether sulfates are used in a solvent-free toner production process as surfactants to provide for higher parent particle charge without adversely affecting particle size, distribution control and circularity of the toner particles. The present disclosure also provides a new formulation and process for the emulsification of polyester resins to form nano-scale particles dispersed in water (latex) without the use of organic solvents by an extrusion process.
