The invention provides 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 is a bond or linker group, on condition that the amount of carboxy functional compound of Formula (1) provided in acid and/or salt is at least 1,5% by weight; d) mixing the latex dispersion, colorant dispersion, optional way dispersion and said carboxy functional compound; and e) causing the particles in the mixture to associate. The process advantageously may produce a toner of small size and narrow particle size distribution. |
