ABSTRACT:
Coating compositions for making films having reduced surface resistivity are described herein. These compositions are clear and produce films that are clear and transparent enough to read newsprint through the films. The compositions include colloidal silica, a choline based antistat, and a film-forming binder which is a (meth)acrylic polymer having a quaternary ammonium salt moiety in the polymeric molecule.
