Scratch-resistant conductive coatings

摘要

Novel mixts. claimed for use in the prodn. of scratch-resistant, elec. conductive castings comprise (A) a polythiophene contg. a polythiophene<+> An<-> salt, the polymer having positively charged and uncharged repeat units of formula (I); and (B) a casting material hardenable by ionising radiation. R<1> and R<2> = H or 1-4C alkyl or together form an opt. substd. 1-4C alkylene residue such as alkyl-substd. methylene, 1,2-ethylene opt. substd. by 1-12C alkyl or phenyl, 1-3-propylene or 1,2-cyclohexylene; and An<-> = a polyanion.
