The present invention is directed to a release coating composition comprising a polymer of butadiene, styrene, acrylonitrile polymer having a T from 0&deg; C. to about 75&deg; C. The present invention is also directed to an article of manufacture having a release coating comprising the polymer for pressure sensitive adhesives.

Release coating for tapes

The present invention relates to the use of compositions comprising at least one aqueous polymer dispersion wherein the polymer has carbonyl or oxirane groups (component a)) and at least one compound with at least two NH,groups per molecule as sealing or coating compositions, especially for substrates with a hydrophobic surface. The present invention further relates to coating compositions containing such binder formulations.

Use of polymer dispersions as binding agents for sealing compounds and coating compounds

The present invention relates to a method of coating substrates, especially those with a hydrophobic surface, in which the substrate to be coated is coated with a coating composition whose binder is a formulation comprising an aqueous polymer dispersion in which the polymer has carbonyl or oxirane groups (component a)), and at least one compound having at least two NH.sub.2 groups per molecule, is applied to the substrate to be coated �sic!. It also relates to coating compositions including such binder formulations, and furthermore to a method of sealing using a sealing composition including such formulations as its binder.
