Abstract: Heat-hardenable coating compsns., present as aq. dispersions, consist, by wt., of (A) 50-80% water and (B) 20-50% polyesterimide present as particles having dia. =5 mu. (B) contains 0.2-10 wt.% of at least one esterification catalyst. Dispersion has pH 5-9. Used for wire lacquering, insulating metal conductors, esp. wires and rails. Dispersions have good processing ability and storage stability. Gloss and smoothness of stoved lacquers cannot be distinguished from lacquer of same binder applied from soln.

Abstract: The invention relates to a blocking film, in particular hot blocking film, consisting of a carrier film and a transfer layer which can be removed therefrom and which has at least one magnetic layer of a dispersion of magnetisable particles based on chromium dioxide and/or iron oxide, and which may carry, on the side facing away from the carrier film, an adhesive layer which serves for fixing the transfer layer to a substrate.

Abstract: Magnetic recording media are produced by dispersing pulverulent magnetic material in a mixture of a solvent, an organic polymer binder, a dispersant and other conventional additives, with the aid of a conventional dispersing apparatus and using a particular ceramic grinding medium, applying the resulting dispersion in the form of a layer on a base and then compacting the layer.
