Claims23
An antimicrobial material comprising a latex comprising polymer particles and a primary surfactant component, where the primary surfactant is an anionic surfactant, and the polymer particles comprise
- (a) at least one monomer unit;
- and
- (b) at least one surface active agent unit, wherein
- the monomer unit is derived from an ethylenically unsaturated monomer;
- the surface active agent unit is derived from a polymerizable antibacterial quaternary ammonium compound;
- and
- the ethylenically unsaturated monomer and the polymerizable antibacterial quaternary ammonium compound have reacted to form polymer particles.
