The present invention provides a process for producing a fine organic pigment which is capable of efficiently atomizing a raw material organic pigment, and excellent in productivity of the fine organic pigment. The present invention relates to a process for producing a fine organic pigment which includes the step of kneading a mixture prepared by compounding a raw material organic pigment, a water-soluble inorganic salt, a water-soluble organic solvent and a resin, in which the resin is a copolymer produced by copolymerizing an aromatic ring-containing ethylenically unsaturated monomer (A), a carboxy group-containing ethylenically unsaturated monomer (B) and an ethylenically unsaturated monomer (C) containing a polyethyleneoxide chain having an average molar number of addition of ethyleneoxide of not less than 1 and not more than 50.

Methods for forming latexes are provided. In an embodiment, such a method comprises adding a monomer emulsion comprising water, a monomer, an acidic monomer, a hydrophilic monomer, a difunctional monomer, a first reactive surfactant, and a chain transfer agent, to a reactive surfactant solution comprising water, a second reactive surfactant, and an initiator, at a feed rate over a period of time so that monomers of the monomer emulsion undergo polymerization reactions to form resin particles in a latex. The reactive surfactant solution does not comprise monomers other than the second reactive surfactant, the reactive surfactant solution does not comprise a resin seed, and the monomer emulsion does not comprise the resin seed. The latex is characterized by a viscosity in a range of from about 10 cP to about 100 cP as measured at a solid content of about 30% and at room temperature. The latexes are also provided.
