Patent ID: 7736538

Claim:
A mixture comprising: at least one substance A in the form of electrically conductive hard particle having a Mohs hardness of at least 5.5; at least one substance B in the form of very soft or soft, inorganic, electrically conductive or semiconducting particle which are capable of sliding, at least one substance C in the form of a metallic, soft or hard, electrically conductive or semiconducting particle or carbon black; at least one binder; and at least one of a crosslinking agent or a photoinitiator, one additive, one corrosion protection pigment D, one corrosion inhibitor which is not present in particle form; and at least one of an organic solvent or water, wherein A, B and C are water-insoluble or sparingly water-soluble pigments, wherein the sum of the weight contents of the at least one substance B and the at least one substance C makes up 0.25 to 99.5% of the weight content of the water-insoluble or sparingly water-soluble pigmentation Σ(A+B+C), and the particle size substance A, based on the particle size transfer value d 99 measured with a Mastersizer of type S from Malvern Instruments, is less than 10 μm, and wherein said Σ(A+B+C) relative to the sum of the total pigmentation Σ(A+B+C +D) is 30 wt. %.
