Magnetic recording carrier containing radiation-curable dispersants

摘要

The invention relates to a magnetic recording carrier which, in the magnetic layer and/or backing, contains, in addition to the conventional additives, radiation-curable dispersants based on ethylenically unsaturated phosphoric ester mixtures which are products of the reaction of (A) an acrylic ester (acrylate) and/or oligoacrylate containing one OH group per molecule, (B) an alcohol containing one OH group per molecule and (C) phosphorus pentoxide, and where the reaction products have acid numbers of less than 200.
