Abstract
Provided is a silicone resin coated silicone elastomer particle which can be easily produced on an industrial scale, has superior dispersibility and oil absorptivity in a curable organic resin such as an epoxy resin, and has superior workability due to low secondary aggregation compared to conventional silicone elastomer particles. Also provided are applications containing the particles such as organic resin additives, organic resins, coating compositions or coating agent compositions, and cosmetic compositions. The silicone resin coated silicone elastomer particles have part or all of their surface coated with a silicone resin made up of two types of siloxane units. The siloxane units are selected from D units represented by RSiO, T units represented by RSiO, and Q units represented by SiO. The particles also have a structure in which at least two silicon atoms in the particles are cross-linked by a silalkylene group with 2 to 20 carbon atoms.
