  • Patent number: 4734445
    Abstract: Latex compositions suitable for applications requiring surface hydrophilicity are disclosed. The latexes can be used in liquid film-forming compositions which comprise: (1) a liquid phase such as water, water-miscible solvents and mixtures thereof; and (2) latex particles dispersed in the liquid phase. The particles comprise an elastomeric hydrophobic core with a hydrophilic "shell" which is integral with the core. When the liquid phase is removed, the particles are capable of forming an elastomeric film having a substantially permanent hydrophilic surface.
