Abstract

Microcapsules are obtainable by polymerisation of A) 30 to 100% by weight of one or more C1-C24-alkyl acrylates and/or methacrylates (monomers I), B) 0 to 80% by weight of a bifunctional or polyfunctional monomer (monomers II) which is soluble in solvents which are insoluble or sparingly soluble in water, and C) 0 to 40% by weight of other monomers (monomers III), the solvent, if any, being in the form of a stable oil-in-water emulsion together with the monomers and a free-radical initiator as the disperse phase, and the polymerisation being initiated and controlled by the thermal decomposition of the free-radical initiator. The products preferably serve for the manufacture of pressure-sensitive recording materials.
