Patent ID: 6939656

Claim:
A method for producing a polymerized toner, comprising: a process P1 of producing a dispersion of colored polymer particles, the process comprising a step S1 of polymerizing a polymerizable composition in an aqueous dispersion medium, which polymerizable composition has a colorant and a polymerizable monomer; a process P2 of reducing the remaining polymerizable monomer from the colored polymer particles, the dispersion being treated by stripping in the presence of at least one antifoaming agent selected from a group consisting of fats-and-oils antifoaming agents, mineral oil antifoaming agents, polyether antifoaming agents, polyalkyleneglycol nonionic surfactants, emulsions consisting of fats-and-oils and polyalkyleneglycol nonionic surfactants, and emulsions consisting of mineral oils and polyalkyleneglycol antifoaming agents; and a process P3 of removing the colored polymer particles from the dispersion after treating by stripping.
