Process for troublefree coating of hydrophobic materials with polyurethanes A b s t r a c t The present invention relates to a process for troublefree, i.e. Flaw-free and uniform, coating of a support which can accept a large amount of electrostatic charge, such as, for example, polycarbonate foils, with a solution of fully reacted polyurethane in organic solvents, more precisely after prior coating of the polycarbonate foil with an organic solution of the sodium salt of polystyrenesulphonic acid.
