Patent ID: 7862979

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, on condition that the amount of carboxy functional compound of Formula (1) provided in acid and/or salt form is at least 1.5% by weight, wherein the amount of carboxy functional compound is calculated according to the following equation: amount of carboxy functional compound content (% weight)=100Ã—weight of carboxy functional compound/ (weight of carboxy functional compound+weight of solids of latex, colorant and optional wax dispersions+weight of any additional surfactant) 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.
