PROBLEM TO BE SOLVED: To provide a method for producing a dispersion liquid in which dispersoid, such as solid particles, is finely dispersed in a dispersion solvent.SOLUTION: A method for producing a dispersion liquid (L) has a step in which a mixture (X) with dispersoid (A) dissolved in medium (M) comprising compressible fluid (F) is mixed with a solvent (IS) in which the solubility of the dispersoid (A) in the solvent (IS) is 30 wt.% or less based on the weight of the (IS), to precipitate particles (P) comprising the dispersoid (A).SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】固体粒子等の分散質が分散溶剤中に微細に分散された分散液を製造する方法を提供する。【解決手段】分分散質(A)が圧縮性流体(F)を含む媒体(M)に溶解している状態の混合物(X)と、溶剤(IS)に対する分散質(A)の溶解度が、(IS)の重量に基づいて30重量%以下である(IS)とを混合し、分散質(A)を含有する粒子(P)を析出させる工程を含む分散液(L)の製造方法。【選択図】図1
