| abstract |
An improved manufacturing process for preparing a polymer latex for use in toners without solvent. In some embodiments, alkyl sulfates or alkyl ether sulfates are used as surfactants in solventless toner manufacturing processes without adversely affecting toner particle size, distribution control, and roundness. Give parent particles with high charge. Also provided are new formulations and processes for emulsifying polyester resins and producing nano-sized particles dispersed in water (latex) without the use of organic solvents by an extrusion process.
