PRODUCTION OF PHARMACEUTICAL PROTECTIVE OVERALLS WITH GOOD RESISTANCE IN A NEUTRAL ENVIRONMENT

摘要

Coating obtained from a film-forming coating agent comprising copolymers of N,N-diethylaminoethyl methacrylate and methyl methacrylate in a weight ratio of 35:65-55:45, is claimed. The copolymers are partially neutralized with dicarboxylic acids having 3-10 carbon atoms. An independent claim is also included for producing the coating agent for coating dosage forms containing at least one active substance, exhibiting a resistance against premature release of the active substance.
