  • PROCESS FOR PRODUCING A MICROCAPSULE DISPERSION COMPRISING MICROCAPSULES WITH A HYDROPHILIC CAPSULE CORE
    Publication number: 20160145459
    Abstract: The present invention relates to a process for producing a microcapsule dispersion comprising microcapsules comprising a hydrophilic capsule core and a capsule wall polymer, wherein a water-in-oil emulsion comprising a hydrophobic diluent as continuous phase, and the hydrophilic capsule core material, a monomer composition and an amphiphilic polymer is produced and then the monomers are free-radically polymerized, where the monomer composition comprises 30 to 100% by weight of one or more monomers selected from C1-C24-alkyl esters of acrylic acid and/or methacrylic acid (monomers I), 0 to 70% by weight of one or more monomers selected from acrylic acid, methacrylic acid, maleic acid, acrylic acid esters and/or methacrylic acid esters which carry hydroxy and/or carboxy groups (monomers II), 0 to 50% by weight of one or more monomers which has two or more ethylenically unsaturated radicals, (monomers III) and 0 to 30% by weight of one or more other monomers (monomers IV) in each case based on the total weight o
