reactive materials studies摘要：A material suitable as crosslinking binder component for pigment- containing coatings and having an average molecular weight of from 25,000 to 150,000, obtainable by reacting a polyurethane comprising a diol having a molecular weight between 400 and 4,000, an aliphatic or cycloaliphatic diol of 2-18 carbon atoms, an aromatic diol of 8-36 carbon atoms, a trihydric or polyhydric alcohol of 3-18 carbon atoms, a polyhydric alcohol of 3-40 carbon atoms containing a tertiary amino group, and a diisocyanate of 3-34 carbon atoms with a compound containing one or more hydroxyl groups and one or more amino groups reactive toward isocyanate groups. The materials may be used as crosslinkable binder components for pigment-containing coatings, in particular for the production of magnetic recording materials.
