Low melt toners and processes thereof

A method for forming a low melt toner, the method comprising:

• forming a pre-toner mixture comprising (i) an emulsion resin comprising a first alkali sulfonated polyester resin and a second alkali sulfonated polyester resin, (ii) a colorant, and (iii) optionally a wax;
• adjusting the pH of the pre-toner mixture to between about 4 to about 5;
• homogenizing the pre-toner mixture;
• forming an aggregate mixture of aggregate toner particle by adding an aggregating agent over a period of about 10 to about 60 minutes;
• adjusting the pH of the aggregate mixture to between about 5 and about 7;
• heating the aggregate mixture to a temperature of from about 50 to about 80° C. thereby forming a mixture coalesced toner particles;
• controlling toner particle size by adjusting the pH of the mixture of coalesced toner particles to between about 5 and about 7;
• and
• cooling the mixture of coalesced toner particles to room temperature.
