Aqueous, autocrosslinking polymer dispersion binders comprising polyhydrazides and carbonyl-containing polyurethane-vinyl hybrid polymers and also, if desired, conventional additives, are useful in base coatings, aqueous coatings, adhesives and printing inks.

Aqueous, autocrosslinking polyurethane-vinyl hybrid dispersions

Curing agents for aqueous epoxy resin dispersions obtained by reaction of an adduct (A) of at least one polyepoxide (A.sub.1) and at least one polyalkylene polyether polyol (A.sub.2), it being possible for the adduct (A) to be modified with a secondary amine (A.sub.3) if appropriate, with I. a reaction product of an amine (B) and an epoxide (C) or II. an amine (B) and subsequent reaction with an epoxide (C), the amount of amine (B) being chosen such that the H atoms on the nitrogen are present in a 2- to 10-fold excess, based on the epoxide groups in (A).

Aqueous epoxy resin dispersions

Crosslinked polymer microparticles based on epoxy resin obtained by polymerization of aqueous dispersions (A) of compounds containing epoxide groups in the presence of up to 0.2 mol, preferably 0.02 to 0.15 mol (based on the nitrogen contained in (B)) of a nitrogen-containing organic compound (B) per epoxide equivalent and subsequent isolation which are preferably in the form of aqueous dispersions thereof, and are suitable as organic fillers, pigments, matting agents and/or reinforcing agents for binder systems and individual components thereof, paint formulations, coating and molding compositions, intermediate coatings, adhesives and the like, preferably based on water.
