Abstract

To provide a method for producing an acrylic organic fine particle that is excellent in dispersibility in epoxy resin.SOLUTION: Provided is a method for producing an acrylic organic fine particle, which is a method for producing an acrylic organic fine particle having a core part and a shell part, and in which the core part has a glass transition temperature of -100 to -30°C, contains, as a monomer forming the core part, a monomer having 2 or more unsaturated groups, the shell part has a glass transition temperature of 80 to 120°C, and a hydroxyl group-containing saturated compound having 6 to 20 carbon atoms is added before the extraction process.SELECTED DRAWING: None
