Abstract
The present invention is directed to a process for the preparation of an aqueous dispersion of coacervates having a core-shell structure, the core (a) being an inorganic particle being anionic or cationic and the shell (b) being a copolymer wherein said copolymer comprises at least two parts, A and B, part A being cationic if particle (a) is anionic, and anionic if particle (a) is cationic, and part B being neutral in pH conditions of said dispersion. More particularly, the invention is directed to treating compositions comprising that aqueous dispersion of coacervates delivering antifouling, water sheeting, antisoiling, anti-adhesion, adhesion, anti-deposition, and/or anti-UV properties onto all kinds of surfaces.
