Calcium oxide or hydroxide to improve the charge acceptance of electrographic dielectric resins
The charge accepting capacity of electrographic dielectric coatings is improved by dispersing in an organic solvent-soluble thermoplastic insulating resin having carboxyl functionality providing an acid value of from 5-100, from 0.05-3% by weight of calcium oxide or calcium hydroxide.
