the invention relates to a method for producing a plastic molded part comprising an integrated conductor path , which plastic molded part is used in particular as an intermediate product to be further processed into an electrically heatable mirror . the method steps are : a ) producing a substrate from a carrier body made of an electrically insulating plastic material having a conductor path made of an electrically conductive material on or in a surface of the carrier body , b ) flooding the surface of the substrate equipped with the conductor path or the surface of the substrate opposite said surface with a liquid , electrically insulating coating material . the flooding evens out depressions due to uneven shrinkage in the thick and thin areas of the carrier body and a smooth surface can be produced , which can subsequently be covered with a reflective layer .
