Abstract: Urea-aldehyde polycondensates usable as surface coating binders are obtainable by step-wise reaction of (a) urea and/or urea derivatives with acidic CH aldehydes in a molar ratio of urea:aldehyde of 1:2 in the presence of acids and at from 60 DEG to 120 DEG C. with (b) a mixture of 3 moles of formaldehyde per mole or urea and 3 moles of an acidic CH aldehyde per mole of urea at from 60 DEG to 120 DEG C. with subsequent removal of the water of reaction and treatment of the reaction mixture with an alkali metal alcoholate at from 80 DEG to 100 DEG C.

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.
