Abstract:
1. A microcapsule comprising a capsule core and a capsule wall, wherein the capsule wall is formed from at least one polymer comprising: (A) 60% to 90% by weight of one or more C (B) 10% to 40% by weight of a mixture of divinyl and polyvinyl monomers, as monomer II, wherein the divinyl monomer is at least one diester of a diol with acrylic acid and/or methacrylic acid and the polyvinyl monomer is at least one polyester of a polyol with a acrylic acid and/or methacrylic acid, wherein a fraction of the polyvinyl monomers is in the range from 2% to 90% by weight based on the monomers II, and (C) 0% to 30% by weight of one or more additional monomers other than monomers I and II, as monomer III, wherein the weight percent of (A), (B), and (C) is based on the total weight of the monomers, and wherein the capsule core comprises a lipophilic substance having a solid/liquid phase transition in the temperature range from 0 to 60° C. and which is a saturated or unsaturated C
