Claims
- 1. A conductive composition consisting essentially of a dispersion of 20 to 95 percent by weight of a water-soluble gel forming binder polymer selected from polyvinyl alcohol or polyvinyl alcohol cross-linked to a water-insoluble and water-swellable form by reaction with a coreactive water-soluble polymer and a linear, water-soluble polyelectrolyte of the formula: ##STR16## where Z is chloro, bromo or iodo and n is an integer such that the intrinsic viscosity, n, as determined by light scattering in 0.4 KBr is at least 0.2 dl/g as determined by the formula:
- n= (2.94 .times. 10 .sup..sup.-4) M.sup.0.61
- where M is molecular weight.
- 2. A composition according to claim 1 in which the water soluble binder polymer comprises polyvinyl alcohol.
- 3. A composition according to claim 1 in which the polyelectrolyte is present in an amount from 10-30 weight precent of the composition.
- 4. A composition according to claim 3 further including up to 50 weight percent of an inert filler.
- 5. A composition according to claim 4 in which the filler is a reprographic paper grade of clay.
- 6. A composition according to claim 1 in which Z is chloro.
- 7. A conductive composition according to claim 1 in which the coreactive polymers are polyvinyl alcohol and polyacrylic acid.
