    Abstract: Binder compositions containing inorganic fillers and thermoplastic polyurethane block copolymers with soft and hard segments, in which at least one hard segment contains a bicyclic structural element formed by the criss-cross polyaddition reaction between a di-isocyanate and an azine compound. A binder composition (BC) containing (at least) (i) an inorganic filler and (ii) thermoplastic polyurethane block copolymer(s) (TPU) with soft segment(s) (A) and hard segment(s) (B), in which at least one of the hard segments contains a structural element of formula (I): R , R = optionally substituted 4-20C aromatic or heteroaromatic groups, with R = R = H, or R -R = essentially completely fluorinated 1-10C alkyl; R , R = linear or branched aliphatic residues, cycloaliphatic residues or aromatic residues (all with 4-20C, all optionally substituted); n = 1-100 . An Independent claim is also included for a method for the production of BC by mixing components (i) and (ii) together.

    Abstract: Thermoplastic polyurethane (TPU) block copolymers with soft segment(s) (A) and hard segment(s) (B), in which at least one hard segment B contains anionic, cationic or non-ionic anchor group(s) (L) or a mixture of two such groups. Independent claims are also included for the following: (a) binders containing TPU as described above; (b) magnetic dispersions containing a binder as in (a) and magnetic or magnetisable material(s); (c) a process for the production of TPU by reacting at least difunctional, NCO-terminated, linear or branched polyurethane prepolymer(s) (as hard segment) with linear or branched soft segment(s) containing functional groups which are reactive towards isocyanate groups; and (d) magnetic recording media containing binders as in (a).
