A process comprising heating a sulfonated polyester resin latex and a colorant below about the glass transition temperature (Tg) of the sulfonated polyester resin, adding a metal stearate to the resulting slurry, and isolating the product, and wherein said heating generates an alkyl carboxylate metal salt component ionically attached to the surface of said product.
A toner process comprising mixing a sulfonated polyester resin with a colorant;
- heating the resulting mixture below the glass transition temperature (Tg) of the sulfonated polyester resin;
- heating above the Tg of the sulfonated polyester resin;
- and subsequently adding a metal stearate.
A process comprising heating a polyester resin, colorant and a metal stearate, which heating includes a first heating at a temperature below the Tg of said resin, and a second heating above the Tg of the polyester resin;
- and thereafter optionally isolating the product.
