Abstract
An article comprising a paint film disposed on at least a portion of a thermoplastic section. The thermoplastic section is made of a thermoplastic composition. The thermoplastic composition has a compatibilized blend of a poly(arylene ether) and a polyamide, an electrically conductive carbon black, and an impact modifier. The electrically conductive carbon black has agglomerates and the agglomerates have an average agglomerate size greater than or equal to 30 square micrometers. The weight ratio of electrically conductive carbon black to polyamide is greater than or equal to 0.043.
