ABSTRACT:
A magnetic recording carrier which has improved mechanical properties as a result of a highly active cross-linking reaction of the polymeric binder is produced by carrying out the cross-linking reaction by way of oligo- and/or polyurethanes and/or polyureas containing oxadiazine trione rings in the presence of hydroxyl groups and/or aliphatic amino groups. The oligo- and polyurethanes containing the oxadiazine trione ring are reaction products of
