ABSTRACT:
The accumulation of electrostatic charges in an abrasive article having a flexible backing sheet, a layer of adhesive and abrasive grains embedded in the adhesive is prevented by incorporating an electroconductive metal pigment or ionizable salt in an inner layer of the article and sandwiching this layer between two layers of substantially lower electroconductance so as to insulate the inner layer.
