Disclosed is a process for forming a hydrophilic and bioactive coating on a surface of a polymer substrate, in which a hydrophilic or hydrophilized polymer substrate is treated with a polyalkyleneimine as a primer or with ammonia plasma, and a hydrophilic, bioactive coating polymer that contains (a) a carboxyl or carboxylate group, (b) a sulfonic acid or sulfonate group or (c) a sulfuric acid ester or sulfate group is applied to this pretreated substrate. The coated substrate can be used for technical, medico-technical, hygienic, or biotechnical purposes.
