<p>A microcapsule comprising a core containing a hydrophobic liquid or wax a nd a polymeric shell formed from: i) 1 to 20% by weight of polymerisable sil ane compound, ii) 1 to 94% by weight of hydrophobic mono functional ethyleni cally unsaturated monomer, iii) 5 to 98% by weight of polyfunctional ethylen ically unsaturated monomer, and iv) 0 to 60% by weight of other mono functio nal monomer(s), wherein components (i), (ii), (iii) and (iv) total 100%, and in which the microcapsule also includes a hydrophilic polymer which is cova lently bonded to the microcapsule. The invention includes a process for the manufacture of particles and the use of particles in artic les, such as fabr ics, and coating compositions, especially for textiles.</p> |
