Abstract

The invention relates to a process for preparing a conductive curable moulding compound with reduced electrical surface resistance, comprising mixing together an unsaturated polyester resin, a thermoplastic polymer, a conductive paste and optionally a filler, and is characterized in that the conductive paste is obtained by dispersing conductive pigment particles in a solution of a thermoplastic polymer in a suitable solvent. The invention further relates to the conductive paste itself and to mouldings having reduced surface resistance, obtained therefrom.
