Patent ID: 7763275

Claim:
A method for the non-discontinuous production of microcapsules having a diameter of from 20 nm to 40 μm, comprising the steps of, providing a suspension of template particles in an aqueous medium, adding a first polyelectrolyte coating having a complementary charge with respect to the template particles to the suspension in a first amount equivalent to a titration point at which said first amount essentially binds completely to the surface of the template particles to form a first coating layer and an aggregate-free suspension, and without performing a separating, filtering or washing step, adding to the suspension at least one additional polyelectrolyte coating having a complementary charge with respect to the first polyelectrolyte, in an additional amount equivalent to a titration point at which said additional amount essentially binds completely to the surface of the first coating layer to form an additional coating layer and an aggregate-free suspension.
