Title:
CRYSTALLINE RESIN-FINELY DISPERSED ORGANIC COMPOSITION
Document Type and Number:
Japanese Patent JP3199791
Kind Code:
B2
Abstract:
PURPOSE: To obtain the composition comprising a crystalline resin extremely finely dispersed in a specific organic substance by dissolving the crystalline resin in a solvent at a high temperature or at the ordinary temperature, and subsequently cooling the solution or adding a poor solvent or specific organic substance to the solution.
CONSTITUTION: (A) A crystalline resin is dissolved in (B) a solvent at a high temperature or at the ordinary temperature, and subsequently the produced solution is cooled or (C) a poor solvent is added to the solution to deposit crystalline resin particles having fine particle diameters. Before the component A is dissolved in the solvent or after the deposition of the component A from the solvent is initiated, a liquid having a boiling point higher than that of the component B or a liquid or unevaporative solid organic substance having no boiling point is added to the solution, followed by distilling off only the solvent to obtain the objective crystalline resin-finely dispersed organic composition particles.
