Abstract
In a resistance paste for the production of electric resistors consisting of a polymer binding there are dispersed electrically conductive particles, solvents and additives; in order to produce resistance layers which are electrically stable and resistant to organic substances such as fuels and oils within a temperature range of from -55.degree. C. to +160.degree. C., more than half of the solids contained in the polymer binder consists of a mixture of PA1 a) fully etherified melamine resin, PA1 b) polyester resin containing hydroxyl groups and PA1 c) an acidic catalyst.
