Abstract:
A coating composition comprising:(a) a volatile aqueous liquid medium; and (b) binder dissolved or dispersed in the volatile aqueous liquid medium, the binder comprising: (1) water-soluble film-forming organic polymer which is substantially free of ammonium groups, (2) water-soluble first cationic addition polymer consisting essentially of quaternary ammonium-containing mer units and ammonium-free mer units, and (3) water-soluble second cationic addition polymer consisting essentially of secondary, tertiary, or both secondary and tertiary ammonium-containing mer units and ammonium-free mer units, wherein the binder constitutes from 20 to 90 percent by weight of the solids of the coating composition; and (c) finely divided substantially water-insoluble filler particles which have a maximum dimension of less than 500 nanometers and constitute from 10 to 80 percent by weight of the solids of the coating composition.
