ABSTRACT:
Latex compositions suitable for applications requiring surface hydrophilicity are disclosed. The compositions comprise: (1) a liquid phase selected from the group consisting of water, water-miscible solvents and mixtures thereof; and (2) latex particles dispersed in the liquid phase. The particles comprise an elastomeric hydrophobic core and a hydrophilic "shell" which is integral with the core and which colloidally stabilizes the latex particles in the liquid phase. The shell comprises moieties L-Q attached to the core, wherein Q is a nonionic group end-capped with a cationic moiety, and L is a linking unit. When the liquid phase is removed, the particles are capable of forming an elastomeric film having a substantially permanent, cationic, hydrophilic surface. The cationic moiety helps the latex particles become attracted to anionic surfaces such as cellulosic materials.
