Abstract: A process for the preparation of stable aqueous aldehyde resin dispersions and for the production of surface coating binders. For this purpose, a melt or highly concentrated solution of a polycondensate of urea and a CH-acidic aldehyde, with or without formaldehyde, is dispersed in water in the presence of an organic protective colloid and, if required, an emulsifier. These aqueous resin dispersions can be used, in combination with other film formers, as surface coating binders.

Abstract: A process for the preparation of a stable aqeuous ketone resin or ketone/aldehyde resin dispersions and a process for the production of surface coating binders. For this purpose, a melt or a highly concentrated solution of the ketone resin or ketone/aldehyde resin is dispersed in water in the presence of an organic protective colloid. These aqueous resin dispersions can be used, in combination with other film formers, as surface coating binders.
