摘要

The present invention relates to spherical microparticle compositions composed of a wall material and at least one cavity containing a gas and / or pore-containing liquid on its surface, the spherical microparticles having an average particle diameter of 10 µm. At least 80% of those microparticles whose particle diameters deviate from the average particle diameter of the composition microparticles by no more than 20% each have at least 10 pores whose diameter is in the range 1 / 5,000 to 1/5 of the average particle diameter and furthermore the diameter of these pores is at least 20 nm, the wall material consisting of a composition containing at least one aliphatic-aromatic polyester and The wall has a solubility at 25 ° C of at least 50 g / l in dichloromethane, a process for producing them and using them.
