Abstract
Improved conductive latex dispersions are disclosed comprising a specific blend of conductive carbon black particles. The carbon black component of the blend comprises acetylene carbon black particles and furnace black particles, with the furnace black particles having a nitrogen surface area (m.sup.2 /gm) of about 250 or greater and a DBP absorption value cc/100 gm of about 180 or above. The dispersions exhibit stable viscosity upon usage and storage and still result in acceptable conductivity.
