Abstract: La presente descripción proporciona procesos para producir pigmento orgánico. En modalidades, se usan alquil o alquil éter sulfatos en un proceso de producción de pigmento orgánico sin solvente como tensioactivos para proporcionar una carga de partícula original más alta sin afectar de manera adversa el tamaño de partícula, el control de distribución y circularidad de las partículas de pigmento orgánico. La presente descripción también proporciona una formulación de un proceso novedoso para la emulsificación de resinas de poliéster para formar partículas a escala nano dispersas en agua (látex) sin el uso de solventes orgánicos por el proceso de extrusión.

Abstract: 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.

Abstract: PROBLEM TO BE SOLVED: To provide a latex polymer meeting an E/A (emulsification agglomeration/unification) toner capable of customizing a latex of a wide Mw range substantially not changing Mn and Tg to keep the performance of good toner. SOLUTION: In a chain transfer agent division emulsion polymerization to manufacture a latex polymer having a wide range of molecular characteristic, the latex polymer is prepared first by preparing a seed particle latex by aqueous emulsion polymerization of a first part of a monomer emulsion liquid, then the seed particle latex is blended with a second part of the monomer emulsion liquid and at least a chain transfer agent. The blending is carried out in the presence of a radical initiator under heating, and the monomer emulsion liquid contains at least a monomer, at least a chain transfer agent, at least a surfactant, and a mixture of polymerization chemical agents in water.
