<p>Water-in-oil emulsion comprises (a) an aqueous phase containing droplets, in which the droplets exhibit a D90 value 10 mu m, (b) a continuous water-immiscible phase and (c) at least one amphiphile (A1) having hydrophilic-lipophilic balance (HLB) value of less than 10, where the aqueous phase comprises an inorganic and/or metal compounds in particle form and the continuous phase is composed of at least partially of at least one monomer and/or a mixture of di- or polyfunctional organic compounds, where the respective monomers with each other undergo polymerization reactions.

An independent claim is also included for an aqueous dispersion is obtainable by a process comprising (i) preparing an oil-in-water emulsion by adding a volume (V1) of an aqueous phase comprising at least one amphiphile (A2) with the HLB greater than 8 to a volume (V2) of a water-in-oil containing at least partly ethylenically unsaturated monomers , (ii) homogenizing under the action of shear force, and (iii) polymerization of the monomers present in the oil phase of the oil-in-water emulsion, where the aqueous dispersion containing dispersed solids with the D90 value of 10 Pm, comprise an organic binder and inorganic and/or metallic particles.</p> |
