    Abstract: The invention relates to microcapsules comprising a capsule core, which contains a lipophilic substance and at least one compound that absorbs electromagnetic radiation from the wavelength range of 700 nm to 1 m, and capsule walls that are constituted of 40 to 80% by weight of one or more monomers (monomers I) selected from C
    1 -C
    24 alkyl esters of the acrylic and/or methacrylic acid, acrylic acid, methacrylic acid and maleic acid, 20 to 60% by weight of one or more bifunctional or polyfunctional monomers (monomers II) which is/are water-insoluble or poorly water-soluble, and 0 to 40% by weight of one or more other monomers (monomers III), each based on the overall weight of the monomers. The invention also relates to microcapsules containing at least one epoxide resin adhesive and optionally a compound which absorbs electromagnetic radiation from the wavelength range of 700 nm to 1 m, to a method for producing the same, to the use thereof in contact adhesives and to methods for gluing at least two substrates.

    Abstract: The invention relates to an aqueous dispersion comprising microcapsules, the capsule wall of which is made of radically polymerised monomers and the capsule core of which comprises at least one oil and at least one lipophilic surfactant. The continuous phase of the dispersion comprises at least one agrochemical. The invention also relates to a method for producing an aqueous dispersion with the steps: i) provision of an aqueous dispersion comprising microcapsules, the capsule wall of which is made of radically polymerised monomers and the capsule core of which comprises at least one oil and at least one lipophilic surfactant (microcapsule crude dispersion), and ii) at least one agrochemical is added. The invention also relates to the use of the microcapsule crude dispersion for producing an aqueous dispersion and to a product comprising, as separate components, a microcapsule crude dispersion and at least one agrochemical for combined use in combating undesired plant growth and/or for controlling undesired insect or acaricide infestation of plants and/or for combating phytopathogenic fungi.
