ABSTRACT:
An aqueous conductivising composition for conductivising paper or other sheet material, for example for producing a conductive base for use in dielectric paper or other electrostatic imaging material, is produced by (a) removing sodium magnesium trifluoride impurity (neighborite) from a synthetic hectorite clay conductivising agent, and (b) adding a binder. These measures reduce dust formation experienced in production or use of electrostatic imaging material incorporating a base which has been conductivised with a synthetic hectorite clay conductivising agent.
