Abstract

The organopolysiloxane particles consist of a single molecule, are crosslinked and have an average diameter of 5 to 200 nm. At least 80% of the particles have a diameter which deviates from the average diameter by not more than 30%. The particles are soluble in a solvent to the extent of at least 5% by weight.
