Polycarbonate resin containing small amounts of carbamate compounds is disclosed. The resin that contains at least one of compounds conforming to ##STR00001## wherein R.sup.1 and R.sup.2 independently of one another denote hydrogen or C.sub.1-C.sub.12-alkyl, or together denote C.sub.4-C.sub.12-alkylidene, R.sup.3 and R.sup.4 independently of one another represent hydrogen, C.sub.1-C.sub.12-alkyl, or phenyl, or together with the carbon atom to which they are bonded form cyclohexyl or trimethylcyclohexyl, and R.sup.5 denotes hydrogen, C.sub.1-C.sub.12-alkyl, C.sub.5-C.sub.12-cycloalkyl, phenyl or cumyl, are characterized by their low electrostatic field and therefore suitable for making optical storage media.
