The invention relates to a producing process for microfined organic pigment, a microfined organic pigment and a microfined organic pigmet coloring composition. the problem to be addressed is to provide a producing method for obtaining microfined organic pigment which can be applied on the coloring film of the liquid crystal television with low lantency, excellent view angle dependency, high transparency, a microfined organic pigment produced thereby, and microfined organic pigment coloring composition using the microfined organic pigment. The invention solves the problem by the producing process of the microfined organic pigment, which is characterized in that an organic pigment, a water-soluble inorganic salt, a water-soluble organic solvent and a resin (A) are mechanically compounded toobtain a compounding composition, then the water-soluble inorganic salt and the water-soluble organic solvent are removed by water, wherein the resin (A) has solubility of over a weight part with respect to 100 weight parts o
