An electrically conductive adhesive composition effective for repairing discontinuities in the electrically conducting metal lines of rear window defoggers is disclosed. The composition comprises (a) an acrylic ester polymer resin (b) a metallic pigment and (c) an organic pigment.The composition is applied as a solid solution to the interrupted section of the metal line to bridge the gap in the line and the solvent is evaporated leaving an electrically conductive bridging layer which restores electrical flow to the line. The T.sub.g of the acrylic ester polymer resin should be such that the composition does not run, sag or otherwise lose its structural integrity when the metal line is heated to an operating temperature.
