Claim:
A process for the manufacture of a toner which comprises the steps of: a) providing a latex dispersion containing primary resin particles and surfactant; b) providing a colorant dispersion containing primary colorant particles and surfactant; c) optionally providing a wax dispersion containing primary wax particles and surfactant; d) providing at least one carboxy functional compound of Formula (1), which may be in acid, salt and/or complex form: wherein R is a carbocyclic or heterocyclic radical which may be optionally substituted and Z 1 is a bond or linker group and wherein the amount of carboxy functional compound of Formula (1) provided is greater than 3% by weight, the amount of carboxy functional compound being calculated according to the following equation: â¢ amount â¢ â¢ of â¢ â¢ carboxy functional â¢ â¢ compound â¢ â¢ ( % â¢ â¢ weight ) = 100 Ã— weight â¢ â¢ of â¢ â¢ carboxy â¢ â¢ functional â¢ â¢ compound â¢ ( weight â¢ â¢ of â¢ â¢ carboxy â¢ â¢ functional â¢ â¢ compound + weight â¢ â¢ of â¢ â¢ solids â¢ â¢ content â¢ â¢ of â¢ â¢ latex , colorant â¢ â¢ and â¢ â¢ optional â¢ â¢ wax â¢ â¢ dispersions + weight â¢ â¢ of â¢ â¢ any â¢ â¢ additional â¢ â¢ surfacatant â¢ ) â¢ e) mixing the latex dispersion, colorant dispersion, optional wax dispersion and said carboxy functional compound; and f) causing the particles in the mixture to associate by adjusting the pH.
