Abstract
Spherical microcapsules including light reflecting solid integral particles reflecting incoming light in a defined direction for determining the position and orientation of the microcapsule are produced by preparing a first liquid phase containing a first polymerization partner; preparing a second liquid phase containing a second polymerization partner, the first liquid phase not being soluble in the second liquid phase, and the second polymerization partner being configured to polymerize with the first polymerization partner under polymerization conditions; dispersing the solid particles in the first liquid phase; forming droplets of the first liquid phase including at least one solid particle; and immersing the droplets in the second liquid phase under the polymerization conditions. The first polymerization partner and the second polymerization partner polymerize at the surfaces of the droplets forming shells of a polymeric material enclosing the individual droplets, and the light reflecting solid integral particles are fixed to the shells.
